Switch Mgmt. [7:14621]
Hi All, I was trying to monitor the performance of a 2900 series switch. Following was the output for - sh controllers switch. mosswitch#sh controllers switch Switch registers: Device Type : 0x00020173 Congestion Threshold : 0x6E8B Peak Total Allocation: 0x0EAE Total Allocation : 0x Peak Total Bandwidth : 0x09D8 Total Bandwidth : 0x Total Bandwidth Limit: 0x0B55 Lower Bandwidth Limit: 0x0B55 Switch Mode : 0x0020 Cisco site mentions I shld be able to get the performance info by using this comand. I am unable to extrapolate anything out of this output. Please help understanding, how the switch is performing. The response has been fairly slow.

Re: Just how important is route summarization in typical [7:14617]
I thought somebody was going to talk about masking instabilities. But then that begs the question - in a typical enterprise network (therefore a small one of 100 routes or less), if you are suffering from routing instabilities, isn't your time better spent to try to figure out why your routes are so unstable and then remedying it rather than engaging in summarization in order to mask the instability. Like I said previously, I completely agree that summarization is indeed very useful in large networks like NSP/ISP's or large enterprises (1000+ routes), for many reasons (better lookup performance, masking truly becomes useful because you can't be expected to fix all your flaky links in a huge network, etc.). But I would like to understand if summarization can be useful in a typical enterprise network ( wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Performance gains are only a small part of the > picture... what is more important is enforcing a > proper hierarchical addressing scheme that conceals > routing instabilities from the network as a whole, and > lessens the amount of routing update traffic > propagated across the entire network. > > It's gotten to the point > > that Cisco-trained > > personnel treat summarization like the holy grail, > > and they go around trying > > to use summarization techniques wherever they can. > > A network always benefits from the consistent > application of design goals.

URGENT: Routing Issue [7:14618]
Hi Group, I have a Router (RTA) with a Serial port connected to leased line to an ISP . There are two other Routers in my LAN each connected by their serial ports to an ISP. RTA is the defualt gateway for my network. Since RTA is connected to three internet backbones (1 for its serial port, and the other 2 routers), I want to assure network connectivity while providing load balancing, I want to configure RTA so that it will route simultaneously between these three ROUTES to the internet. Can anyone tell me how I should config the RTA router?

I do recommend summarizing as much as possible, without being compulsive about it, even in fairly small networks. But forwarding performance isn't the major motivation when you have, say, 500 routes or less. There are a number of good reasons for doing it. One is to enforce hierarchical design and efficient address space use. This will definitely be important if you ever need to justify assignments of public address space, and it tends to make life generally simpler. Hierarchy tends to localize the effects of mergers and divestitures. It can localize the effects of problems and simplify troubleshooting. It can ease your capacity planning. Summarization also tends to contain the effect of route flapping and similar instabilities, which can have an appreciable load on router processors, especially small ones. As far as your point about suboptimal routing, I find that this tends to be an issue only in the largest networks. The reality is that small networks -- and even large networks -- don't have huge numbers of alternate paths that could be found for optimality. In one 2500 router network I redesigned, only 400 routers routinely had alternate paths (i.e., not dial backup) they used. If anything, the discipline of a hierarchical address plan helps you catch configuration errors early in the process. > >Note, I know full well that ISP's/NSP's and very large enterprises (those >having on the order of thousands of routes) do indeed benefit substantially >from summarization.

Hierarchical addressing vastly reduces the amount of blood that must be spilled, along with other good practices. See RFC 2072.

Re: Just how important is route summarization in typical [7:14612]
Performance gains are only a small part of the picture... what is more important is enforcing a proper hierarchical addressing scheme that conceals routing instabilities from the network as a whole, and lessens the amount of routing update traffic propagated across the entire network. It's gotten to the point > that Cisco-trained > personnel treat summarization like the holy grail, > and they go around trying > to use summarization techniques wherever they can. A network always benefits from the consistent application of design goals. Summarization scales well because of the architecture which flows from a properly addressed network. I can't think of anyone outside of an SP network concerned with global routing table bloat that ever equates the benefits of summarization in terms of increased routing table lookup efficiency. The benefit is that flapping routes and their attendant update traffic are confined to a small manageable area. Not only does this preserve bw but it greatly aids in network management by narrowing the scope of the network that you need to troubleshoot. So, when I weigh > the cons of suboptimal routing as well as the > possibility of > misconfiguration, I find it difficult to see why the > typical enterprise > would ever really want to do summarization, as the > gains are miniscule at > best. If the network architects can't properly summarize, there are bound to be bigger problems than what that particular misconfiguration will bring.

RE: LMI question [7:14206]
LMI is a switch to router protocol. sub-interfaces just bind to individual DLCI's. Therefore, they don't have their own LMI configuration. Only the serial trunk does.

RE: BGP, TCP, & Firewalls [7:14286]
You need to clarify if you're running BGP on the firewall as well. If you are, quit it. If not, then your BGP peers will need to communicate through the firewall, so yes, you will need to allow them TCP access to each other. As for someone probing your firewall to see if you are doing BGP trough it, that's a moot point since it will only be opened to the other BGP speaking router. Anyone scanning from the outside would see that port as being closed.

RE: IBM Token Ring 8228 MAUs [7:14333]
8228 MAUs are made up of micro-switches that get charged (initially) by a 9 volt battery and later kept working from the power of the ring. If it's real old, you may need to recharge it. Never charge a port that is already in the ring - you'll beacon it. Also, you don't need to change RI/RO. When a station "inserts" into the ring, it sends a voltage which flips open this switch. The current from the card pasing the token keeps it open. When the workstation shuts down or it is unplugged, this switch will close, bypassing the port, and the ring keeps going. To expand your token ring network, you put a cable from the RO port to the RI of another MAU. You should then connect that second MAUs RO to the RI of the original MAU. This keeps the ring from wraping. What's nice though is that you can break the ring to insert an 8228 at any time, as long as the ring isn't already wrapped, and not impact anyone. It's a fairly simple device. One of my favorite.

LMI clarification [7:14608]
LMI has local significance. My provider uses Cisco LMI type by default, however we have reconfigured some of the remote sites to "Annex D" LMI type. I believe the "destination" you refer to must mean the provider's local switch. What is important is that your router and the provider's frame relay switch that it directly connects to have the same LMI type configured. Under certain configurations and with certain versions of the IOS, LMI can use an inverse arp process to find the DLCI.

RE: DHCP SERVERS [7:14444]
Sure, the first one that responds wins. They don't even need to be on the same physical network. Let's say that you have DHCP Server #1(10.10.10.10) in the production site and DHCP Server #2 (192.168.1.1) at your DR site. The router is configured with a helper address for both: ip helper-address 10.10.10.10 ip helper-address 192.168.1.1 The broadcast will go to both of them, and the first to respond wins. WARNING: You better have your DHCP servers setup so that they can talk to each other and keep each other up to date as to what addresses they've allocated. Otherwise, you can have problems. They tend to ping the address to see if it's OK, but access lists can make that not work well at times. Check with your DHCP server vendor for info on that part.

Re: LMI Clarification [7:14490]
Crud - I hate replying to my own messages. But I forgot to add something: If you are using Paradyne FrameServer DSUs, you have another thing to worry about. They tend to do auto-negotiation of LMI out their WAN side and Cisco LMI towards your router. With this setup, you are getting your LMI from the DSU, not the switch. So if a DLCI goes down, you can't necessarily see it. This is because the FrameSaver is "intelligent". You can configure a fake DLCI between just you and the DSU so that you have IP connectivity to the unit for support. So in reality, you can pretty much ignore the stats on the router interface, and will need to get onto the DSU itself to find out what is going on.

Re: LMI Clarification [7:14490]
If your LMI doesn't match, it just plain won't come up. Both the router and the switch must agree on their link management packet details, or they won't be able to communicate. Now, what could cause things to bounce is if there is a physical layer circuit problem and you're droping LMI packets. Take a look at show int on your serial and you will see how many LMI packets were sent and received. If they don't match, you had a problem at some point. clear the counters and take a look at it a bit later. Missing one every now and again won't kill you. You have to miss 3 to drop and get 3 to come back on line (if I remember right). You can also debug the LMI packets if you want to see what is inside of them. Mostly, it's just DLCI information. The other reason why you might drop is because (no office to any telco folks) but the telco tends to jack things up on their frame relay networks. We have thousands of frame relay links and every now and again, they will just drop and come back on line. 99.9% of the time, it is because a DLCI went inactive or deleted. If a DLCI goes inactive, it means that you do not have end to end connectivity for that PVC, however, your router and the switch both agree that the thing really does exist. If a DLCI goes DELETED, it means that you probably have an interface dlci command in there, or a static dlci defined, and the switch doesn't agree that it really exists. Either of these two cases can be caused by a misconfiguration on the switch while they're bringing up someone elses frame circuit and can knock you down.

RE: OT: Frame Relay Q [7:14495]
I think that your explanation is pointing more at point to multipoint. It's somewhat confusing. Let's say for instance we have this: Hub (10.1.1.1/24) -> Frame Circuit -> DLCI 20 Site1 (10.1.1.2/24) -> Frame Circuit -> DLCI 30 Site2 -(10.1.1.3/24) > Frame Circuit -> DLCI 40 Notice that each of these guys only has a single DLCI, however, they all sit on the same IP segment. You would use this setup in cases where the remote sites don't necessarily need to talk to each other. If they do, then you have a split horizon problem, and you either need to sub-interface on the hub site, or put in frame-relay maps everywhere. What's confusing about it is that in a normal frame world, you build PVCs to each other directly. So each side of the PVC has a DLCI identifier.

RE: HELP!! EIGRP and Multiple Connections (VLANS) [7:14579]
If I understand what you're saying properly, you probably have a max-paths problem. EIGRP only handles a max of 6 paths very well. Anything over that and it starts getting pissy with you. If you list out the EIGRP topology database, you will see that for every route, you will have an entry for each one of your 12 VLAN interfaces. Since all of these interfaces go to the same routers, they all pretty much are saying the same thing about the routing table. So your router is going to show 12 equal cost paths to your destination. When a route flaps, you're going to have a serious recalculation loop going on since each route for each interface is going to need to get recalculated. Either way though, this should not be causing everything to hang until you clear the eigrp neighbors. Especially since once the neighbors re-peer, it's going to have to do it all over again anyway. Are you also seeing a lot of routes stuck in active? Just curious... I wouldn't be surprised if you are. When the router loops up like that, it can miss updates and responses and will bitch to high heaven. There are a couple of ways to fix this. Honestly, I think for one you should check CCO for any eigrp bugs in your version of code, and update to the latest version. I know that sounds like a TAC answer, but quite often, it's true. Secondly, you can set the value of max paths to something lower - like 2 or 3. That will make him toss out any of those other routes and not calc them all the time. No flames about VLAN1. VLAN1 is highly mis-construed as being a "bad thing (tm)" but that's just because Cisco trains everyone to say that. The only issue with it is that since VLAN1 exists out of the box, you can "accidently" put traffic in the wrong place if you don't know what you're doing. Good luck. Let me know if I guessed this one right.

Honestly, I think for one you should check CCO for any eigrp bugs in your version of code, and update to the latest version. I know that sounds like a TAC answer, but quite often, it's true. Secondly, you can set the value of max paths to something lower - like 2 or 3. That will make him toss out any of those other routes and not calc them all the time. No flames about VLAN1. VLAN1 is highly mis-construed as being a "bad thing (tm)" but that's just because Cisco trains everyone to say that. The only issue with it is that since VLAN1 exists out of the box, you can "accidently" put traffic in the wrong place if you don't know what you're doing. Good luck. Let me know if I guessed this one right.

RE: default routing [7:14593]
There are a couple ways to do this, but first let me make sure I understand what you want to do. Lets say for instance that "Server A" is really a firewall or external gateway to the Internet. You want any traffic that you do not claim in your routing tables to flow to this device. On the router closest to that device, you would put: ip route 0.0.0.0 0.0.0.0 10.1.1.2 ...when a default route goes into a table, it becomes a 'default candidate'. Some routing protocols will only propogate default candidates if they fall on a classful boundary. So for instance, since you are using 10.x.x.x in your example, you cannot make that your default candidate or things just won't make sense in a larger network. So to get around this problem, you need to distribute something else out that can be used as a default candidate - for instance, 192.168.1.0/24, and is unique enough that everyone can agree on the specific route. Example: (Default Traffic EIGRP Router) ip route 192.168.1.0 255.255.255.0 Null0 ip default-network 192.168.1.0 router eigrp 1 redistribute static metric 64 2 255 1 1500 network 10.0.0.0 (Other EIGRP Routers in the Network) Nothing. They should pick up the default candidate. If you do a 'show ip route' on router B, you should now see your 192.168.1.0 route and it should be tagged as a default candidate. As long as you don't have a better default candidate in the table (take out your ip route 0.0.0.0 0.0.0.0 x.x.x.x), all traffic will flow downhill to the router holding that route along the path to 192.168.1.0. So let's extend this beyond just two routers. Let's say you have a corporate core network and you want all traffic to head down there from anywhere in the network that there is no specific route for. Why would you do this? Again, if you either default route to the Internet, or your core knows about routes in other AS's that you don't propogate out into the routing table. You can suck all the traffic down, and then the core will know how to get it the rest of the way, without having to send the route to the rest of the locations. You can now "stub" off all of the other countries and only send them your default network. They can each do their thing, and yet everything will flow back to you if they don't know how to get to it in their table (for instance, to get to another country).

Just how important is route summarization in typical enterprise [7:14601]
Hey all. I'm going to risk starting a flame war by asking the following: I've been struck by just how much importance Cisco courseware places on route summarization. For example, every student who goes through CCNP-level courseware learns about all the various kinds of summarization - OSPF area summarization, OSPF stubs, EIGRP summarization, etc. etc., and how it reduces the size of the route table, thereby improving router performance by speeding route lookup. It's gotten to the point that Cisco-trained personnel treat summarization like the holy grail, and they go around trying to use summarization techniques wherever they can. Yet, I seem to recall somebody wrote a book (I believe it was Berkowitz) that basically stated that the performance gains associated with reducing the route table via summarization is virtually nil in typical corporate networks, because the real delays were caused simply by the serialization time of sending packets over slow WAN links (T-1 and slower). Plus, with fast-switching and its cousins (optimum switching, MLS, etc.), route lookup isn't done all that often , so there is little lookup delay anyway.And besides, most corporate networks aren't very big - typically less than 100 route entries, so how much lookup delay could there be? So, when I weigh the cons of suboptimal routing as well as the possibility of misconfiguration, I find it difficult to see why the typical enterprise would ever really want to do summarization, as the gains are miniscule at best. Note, I know full well that ISP's/NSP's and very large enterprises (those having on the order of thousands of routes) do indeed benefit substantially from summarization. Of this I have no doubt. What I cannot see is why the typical enterprise would really want to use summarization techniques. Anybody have any thoughts on this?

Dennins, Thanks for your input. I'll try to answer your questions inline: "Dennis Bailey" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > How many remote sites off each 7500? Anywhere from 15 to 30 remote sites off of each 7500 (via ATM subinterfaces) > Are the remote sites all 'stub' sites? As far as I can verify, each remote site is totally stubby (i.e. 1 router in/out). However, we're not using OSPF so I can't make it an "official" totally stubby area =) (BTW, that was a joke. I realize your usage of 'stub' simply meant it had no other 'backdoor' connections to our network) > Do the remotes have connections to both 7500's (ie. primary and backup pvc)? I do not believe that any of the remote sites connect to both 7500s. I will check on that, but for now let's assume they do not. > The passive-interface idea you have is probably a good one. Since both 7500s connect to their respective 5500 via a switchport in VLAN 1, I assume I can implement passive interface on all other VLANs that the 5500's RSMs see. This gets to the heart of my issue tho. Does having more than one connection (whether physical cables or logical VLANs) between two routers (RSMs) screw up EIGRP? Shouldn't it still only see 1 neighbor (that it has multiple links to)? > If your remote sites have a connection to both 7500's, make sure that you > have outbound distribution lists on the remote routers so that the remotes > don't advertise anything but what is behind them. Good call.

This way if a remote link bounces, the 7500 will see > the change and deal with it but the RSM's will not be affected. Luckily the addressing is setup in such a way that I can summarize. I was going to even try to one better that by summarizing at the remote router (i.e. so that any changes on that LAN wouldn't send EIGRP updates over the WAN to the 7500). However (get this), the routers on the remote side of the WAN links are "controlled" by each individual location. I only have control over the "centralized" 7500s and 5500s in the core (love those politics). So in an effort to minimize EIGRP updates in the core, I have introduced a summary route for the site that if the primary cause of these EIGRP updates that start the storms. I configured the EIGRP summary route on the FastEthernet interface that connects the 7500 to the 5500. (i.e. the remote site EIGRP updates still come to the 7500, but then the 7500 summarizes on it's outgoing interface to the 5500 as you mention above). So, at least for this one remote site, when changes happen, the 7500 gets the update, but everything else in the network (except the other WAN links hanging off of that same 7500) are shielded from the updates because of the summary. I didn't get a chance to capture a sniff of the recent storm (today), but even since I introduced this summary address (actually, I introduced 2 of them, one for each of the 2 main offending WAN sites) we've had these "EIGRP storms" and shoot CPU usage up. luckily for us it's not enough to make them go to 80-90% or lock up the box, but it's enough to concern me. I'm going to capture all day tomorrow so if there's another storm, I can see which route is being stormed between the 5500s and try to "shut it down" (i.e. introduce a summary in the appropriate place) we'll see Any further comments or input is MORE than welcome =) Mike W. > Dennis > > ""Michael L.

Re: HSRP for a switch [7:14164]
That's the config I use as well. However, (and I'm not flaming you) that is not what I was speaking of, nor what what I believe this gentleperson was asking about. The original poster said "I want to have a second switch with a copy of the primary's configuration and take over automatically once the primary fails". I was speculating on a way to have two completely separate chassis (switches/MSFCs) create a "mirror" and have one that sits in standby while the other is active. What you have there is 2 MSFCs using HSRP with VLANs load balanced across them. As I said in my eariler post, "Unless you have the end devices connected to both switches, you're screwed". You have end devices (your servers) connected to both switches, which is the *only* way this HSRP setup will provide complete redundancy (actually, it's not the HSRP that provides it, but the fact that your end devices are connected to both switches that provides that real redundancy).

RE: Terminal server and Cat6509 [7:14535]
No one has mentioned it yet but make sure that the little pin beside the 6509 console port is in the "in" position. This position allows the rollover cable to work. This position will also allow the 2620 cable to connect directly to the 6509. If this doesn't work it is likely a config issue on the 2620. Another issue issue to ensure that all lines are clear before trying a reverse telnet. Use a "where" command to ensure that you do not have an open connection to the port you are trying to reverse telnet to. If you have an open connection you can clear the line with "clear line x" or resume the connection by typing the line number. --Rich -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of cisco skin Sent: Wednesday, August 01, 2001 1:57 PM To: [EMAIL PROTECTED] Subject: Terminal server and Cat6509 [7:14535] I'm having a piss os a time with a 2620 with a 16port Asych module/octal cables attached plugged into my console port on a 6509.

Re: HELP!! EIGRP and Multiple Connections (VLANS) [7:14579]
How many remote sites off each 7500? Are the remote sites all 'stub' sites? Do the remotes have connections to both 7500's (ie. primary and backup pvc)? The passive-interface idea you have is probably a good one. If your remote sites have a connection to both 7500's, make sure that you have outbound distribution lists on the remote routers so that the remotes don't advertise anything but what is behind them. If your addressing is organized in such a way that you can summarize everything behind each of the 7500's back into the core RSM's that would probably also help. This way if a remote link bounces, the 7500 will see the change and deal with it but the RSM's will not be affected. Dennis ""Michael L.

RE: Way off subject [7:9997]
not true at all or by any means. there are any number of CCIEs whom I know either directly from work or indirectly through the various news lists whose experience was limited to some hands on in small networks plus home lab, various study labs, or rack rental. I know a couple of guys from work whose only real hands on experience was through implementation work ( installing routers ) and the associated troubleshooting that inevitably occurs. most of this work was in 5-10 router networks, and generally frame relay and not very complex routing. It's just a test. Chuck -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Bradley Lowry Sent: Wednesday, August 01, 2001 5:49 AM To: [EMAIL PROTECTED] Subject: Re: Way off subject [7:9997] I don't think you could get your CCIE without experience on a production network. Virtually all CCIEs have 5 years full time hands on experience on a big network. Finish school. It is a far better investment of your time right now. Trying to get a CCIE right now would be a waste of time. Your chances of getting the CCIE are slim to none without several years of big network experience and a 5 router lab. If your school is a Cisco shop, worm your way into the network infrastucture group, or what ever they call it there. I think a CCIE is a great goal and that goal needs to be set realistically. Think of a CCIE like the bar exam or medical boards. Unless you are the kind of person who can read a 500 page physics text book in one sitting and pass the final exam the next day, I would set the CCIE as a 3 to 5 year goal after you got your first Cisco job.

RE: Frame Relay Q [7:14495]
I'm racking my brain trying to think of how one could accomplish this. on the frame ( layer 2 ) level, a DLCI is an end point identifier of a PVC. you need a unique DLCI for each PVC at the hub. one DLCI at the hub for each PVC to a specific hub.

You can "Cisco-ize" a CiscoPro with a small utility program available in the Software Center area of CCO. Think that you need a logon account to access it.

1) Pinouts for the 9 pin "D" serial port adapter to RJ-45 jack and for the rollover cable will be in the CCO documentation for the 2500 series router. Consider buying a console cable kit on eBay. 2) On CCO go to the TAC page. Look under Top Issues to find Password Recovery. 3) Todd Lammle's book is a great place to start. There are tons of sample configs on CCO for free. You can also buy books. 4) See if you can acquire some additional routers.

lab scenarios [7:14524]
Hi, Cisco office located in my country provides a lab consisting of 4 2500 and a cat5000. I don' t think this equipment is enough to prepare for the CCIE lab. Do I have any chance to implement various lab scenarios with these equipments? I cannot afford to buy a home lab( believe it or not I make 1$) so since one-day lab is coming up with no cabling issues, how helpful is it to rent a lab on the internet (e.g. is it enough to do all the scenarios on ccbootcamp)?

Re: Intermittent connectivity loss - Resolved ?!?! [7:14562]
Honestly, we haven't quite figured out what happened. We're running both IP and IPX on the cluster, and we saw a lot of dropped packets on the server. We migrated over to the other node and have not had any dropped packets or loss of connectivity. I'm not convinced that our cluster is setup correctly (I didn't do it). What I found curious is that Compaq Insight Manager emailed me an alert stating there was a loss of communication with the volume and I had time to open the email before I lost connectivity with the server. I know there's a ton of cache memory in the controllers, but I realized then that our problem was not necessarily with the switch but with NetWare. As soon as my machine lost connectivity with the cluster my machine locked up without a Client32 message. This is what has happened to a lot of our users, though some do get a Client32 message. Our "A-Team" will work on this. Of course in half of the offices they put a NetWare cluster they have had problems, and now these same people are building crappy Exchange clusters, but they know what they're doing! Right? NOT! Again, thanks to all who responded. If anyone has any insight into NetWare clusters please contact me.

HELP!! EIGRP and Multiple Connections (VLANS) [7:14579]
Hey all.. kind of a silly question, but how does EIGRP handle updates when there are multiple links between two routers..? Here is the scenario I've got: I have two 5500s connected via etherchannel trunks and a 7500 hanging off each one for WAN connections like so WAN -- 7500 --FastEther--5500 --Etherchannel Trunk -- 5500 -- FastEther -- 7500 -- WAN (careful of wrap) FYI: The 7500s connect to their respective 5500 via FastEther that is in VLAN 1 (no flames!) Every once in a while an EIGRP update comes in from the WAN, and all of a sudden the two 5500's get "hung" in an EIGRP storm... I did a sniffer capture (only in the VLAN I was connected to) and there were over 4,000 EIGRP updates from the two 5500's in 6 seconds. (all for the same route that was passed to them from the WAN by one of the 7500's). CPU goes from ~5% to 30% when this happens and the only way to stop it is to "clear ip eigrp neighbors". Once this command is issued, it's all over. things go back to normal (until it happens again).. My question is this. Since both RSMs on the 5500s see the same VLAN interfaces (since all of the VLANS are trunked between the two switches), they effectivly have 12 (# of VLANs) connections to each other. Could this be causing this "storm" of EIGRP updates? I was under the impression that the RSMs would see each other as a single EIGRP neighbor. I've considered taking all VLAN interfaces (in both RSMs) except VLAN 1 (which connect to the 7500s) and making them passive interfaces. Any input here? I don't have a *clue* what could be causing this EIGRP storm.. I can't say 100%, but I don't think the two 7500s are affected by this storm. TIA, Mike W.

Consider that the space in the restaurant used to seat all customers not being served is like the queue while the kitchen is like the CPU. Using that, my point in the first paragraph was that assuming that customers enter the restaurant (and leave after finishing) at a rate the kitchen can handle, the "queue" wouldn't need to be utilized =) > As an example, it takes 5 ms to transmit a 1024-byte packet on a 1.544-Mbps > T1 link.

That really hits the nail on the head. There is *always* serialization delay (on non-parallel links), so that's where packets can queue. Mike W.

Re: MTU on the Internet [7:14380]
To my knowledge, there are no proponents of sub 1518 byte IP MTU's to be used as defaults on internet routers. I would tend to think that at least 4470 would make sense. Per my previous post in this thread, I am of the opinion that a consensus hasn't been reached at this point on this issue. For information, I would target the IET F since changes in this matter will likely be driven from the vendor space who currently pay some attention to the IETF.. *** REPLY SEPARATOR *** On 8/1/2001 at 5:40 PM Priscilla Oppenheimer wrote: >Have you done a search in Google?

Have you done a search in Google? I would think you could find some info on this with some work. Let us know what you find out. ;-) My thought was that it would not be a good idea to use 572 bytes since so many Internet devices send 1500-byte Ethernet frames. The 572 bytes size would mean routers in the core of the Internet would have to do fragmentation and reassembly which would really slow things down and be a bad idea. So my guess is that the MTU is 1500 or greater wherever possible. Priscilla At 01:19 PM 7/31/01, Nabil Fares wrote: >Greetings, > >What's the common/standard mtu on the internet backbone?

Re: Terminal server and Cat6509 [7:14535]
Just to get all the assumptions out on the table: - The 6509 Supervisor console port takes a standard black or blue Cisco rollover cable to connect to your terminal or terminal emulator. You connect the "CAB-OCTAL-ASYNC=" cable from your 2620 directly to the console port and it should work, providing the router/terminal server is set up correctly. - If you are using redundant Supervisors in the 6509 only the active one will respond. - 1. Am I assuming correctly that you have directly connected your laptop (or other terminal emulator) to the 6509 Supervisor console port with success? 2. Can you connect from your 2620 to other console ports successfully (for example, to the console port on another Cisco router or a Catalyst 2429XL)? Here's a basic terminal server guide in a nutshell. The basic config for the router: ! ip host cat6509 2033 10.0.15.254 ip host voice 2034 10.0.15.254 ! line 33 64 transport input all ! >From the 2620 privileged mode prompt you can type "cat6509", hit Enter, and you will shortly be at the console prompt. This is equivalent to "telnet 10.0.15.254 2033". If you can't connect, try "clear line n", where "n" is the line number from the output of the command "show line." To disconnect from the session hold down the keys "ctrl+shift+6" all together, let go, and type an "x". You should be back at the terminal server's privileged prompt. You can see which sessions are open on the 2620 terminal server by typing "show sessions." You can disconnect session 1 by typing "disconnect 1" or "disc 1."

RE: 2501 router... [7:14553]
The best way to console into to your new router is to connect the console interface to a SONET ring of a major city.

Re: Lab report Juniper's latency problems [7:14543]
>Raveendra Hegde cited the report at http: //www.mier.com/reports/cisco/Cisco12400JuniperM160.pdf. Let's say this report, which was commissioned by Cisco, is the most accurate thing in the world. And your point is? Routers, especially routers in the class of the GSR and M160, are complex systems. There is no one number that makes one better than another in all applications -- there are a series of factors to be considered. Let's put it this way -- I'm actively cooperating in IETF documents http://www.ietf.org/internet-drafts/draft-ietf-bmwg-conterm-00.txt and http://www.ietf.org/internet-drafts/draft-ietf-bmwg-bgpbas-00.txt , which are coauthored by Nortel, Cisco, Juniper, and Nexthop -- and getting feedback from other vendors and users -- just to BEGIN to pin down how to measure the convergence behavior of a BGP router. I assure you that the result of this effort won't be a single number. Nor will forwarding performance (e.g., RFC 2544) produce a single number, much less considering QoS enforcement, filtering, etc. Just throwing out comments about "latency" as if it is the be-all end-all doesn't clarify much. The Mier and Lightreading reports dealt with convergence only with respect to a full table -- what you typically see at cold start. With a router of carrier-class reliability, how relatively important is the time to initialize the whole table, compared to the performance of the constant adding and dropping of routes that goes on constantly?

not cisco but interesting... [7:14547]
This is not cisco, but alot of things aren't. I received this from my brother-n-law. Any vietnam vets out there in cisco land? It is entitled: "Who is doing the honoring?" = Who is doing the honoring? Whether or not you believed in the war, this is the story of an American's reprehensible actions towards other Americans who were ordered to serve and did serve. McCain has "forgiven" her, more in the spirit of making peace with another human being. He would probably not support this award. Pass it on if you agree. Has THAT much time past? Have Americans forgotten? Read this (its signed at the bottom): REMEMBER, SHE WAS KNOWN TO US ALL AS - "HANOI JANE. Jane Fonda is being honored as one of the ''100 Great Women of the Century.'' Unfortunately many have forgotten, and still countless others have never known, how Ms. Fonda betrayed not only idea of our country, but specific men who served and sacrificed during Vietnam. Part of my conviction comes from personal exposure to those who suffered her attentions. The first part of this is from a McDonnell Douglas F-4E Phantom pilot. The pilot's name is Jerry Driscoll, a River Rat. In 1978, the former Commandant of the USAF Survival School was a POW in Ho Lo Prison (the ''Hanoi Hilton.''). Dragged from a stinking cesspit of a cell, cleaned, fed, and dressed in clean PJs, he was ordered to describe for a visiting American ''Peace Activist'' the ''lenient and humane treatment'' he'd received. He spat at Ms. Fonda, was clubbed, and dragged away. During the subsequent beating, he fell forward upon the camp commandant's feet, which sent that officer berserk. In '78, the AF Col. still suffered from double vision (which permanently ended his flying days) from the Vietnamese Col.'s frenzied application of a wooden baton. From 1983-85, Col. Larry Carrigan was in the 47FW/DO (F-4Es). He spent 6 years in the ''Hilton'' -- the first three of which he was ''missing in action.'' His wife lived on faith that he was still alive. His group, too, got the cleaned / fed / clothed routine in preparation for a ''peace delegation'' visit. They, however, had time and devised a plan to get word to the world that they still survived. Each man secreted a tiny piece of paper, with his SSN on it, in the palm of his hand. When paraded before Ms. Fonda and a cameraman, she walked the line, shaking each man's hand and asking little encouraging snippets like: ''Aren't you sorry you bombed babies?'' and ''Are you grateful for the humane treatment from your benevolent captors?'' Believing this HAD to be an act, they each palmed her their sliver of paper. She took them all without missing a beat. At the end of the line and once the camera stopped rolling, to the shocked disbelief of the POWs, she turned to the officer in charge, and handed him the little pile of papers. Three men died from the subsequent beatings. Col. Carrigan was almost number four but he survived, which is the only reason we know about her actions that day. I was a civilian economic development advisor in Vietnam, and was captured by the North Vietnamese communists in South Vietnam in 1968, and held for over 5 years. I spent 27 months in solitary confinement, one year in a cage in Cambodia, and one year in a black box in Hanoi. My North Vietnamese captors deliberately poisoned and murdered a female missionary, a nurse in a leprosarium in Ban me Thuot, South Vietnam, whom I buried in the jungle near the Cambodian border. At one time, I was weighing approximately 90 lbs. (My normal weight 170 lbs.) We were Jane Fonda's ''war criminals.'' When Jane Fonda was in Hanoi, I was asked by the camp communist political officer if I would be willing to meet with Jane Fonda. I said yes, for I would like to tell her about the real treatment we POWs were receiving, which was far different from the treatment purported by the North Vietnamese, and parroted by Jane Fonda, as ''humane and lenient.''

This does not exemplify someone who should be honored as part of ''100 Years of Great Women.'' Lest we forget . . . ''100 years of great women'' should never include a traitor whose hands are covered with the blood of so many patriots. There are few things I have strong visceral reactions to, but Hanoi Jane's participation in blatant treason, is one of them. Please take the time to forward this on to as many people as you possibly can. It will eventually end up on her computer and she needs to know that we will never forget.

I emailed someone at Cisco and asked him if you have your CCNP can you schedule a CCIE lab without a written pass. He responded and said no and he has not heard that rumor.

Re: Is CCIE written still necessary for CCNPs? [7:14518]
I think he's asking if you need to take the CCIE written to schedule the lab if you're already a CCNP. The answer, unless Cisco says otherwise, is that you absolutely have to pass the written before you can schedule an exam. The written exam covers several topics not on the CCNP tests.

Re: Xyplex 1600 as Terminal server For my Routers [7:14526]
Yeah flash card in the models I've seen. They alway have a OS but we buy tons (we have hundreds) direct from Xyplex so they roll out the red carpet.

If you really understand the concepts and theory of how unix systems are designed, you can easily adopt other unices. The problem with the "universal flavor" is that all unices for the most part have their roots within two types of unix systems. BSD and SysV. Most commercial unices will be very SysVish. This means their init scripts are usually different, and the layout is going to be different than a BSD like machine. The freeware OSes tend to be very BSDish. Unfortunately, this puts you in a bind. There really is no "one unix to rule them all". :( Even if you do pick a BSDish like userland like FreeBSD, some binaries are different than say Redhad Linux. Things like "route print" would not work in FreeBSD, but "netstat -rn" would work in FreeBSD and in Solaris x86! In BSDish (and open source) terms, Linux distributions are probably the most used. However, they seem to do a lot of nasty non-standard things like Microsoft. Namely, their GNU route and GNU netstat are drastically different. Plus, their /bin/sh is NOT shell script but rather BASH! ARGH! I feel FreeBSD is far cleaner. In SysV (and commercial) terms, Solaris has definitely become a king. If you want to get good with SPARC hardware, buy a Sun Blade. (not suggested unless you REALLY want to be a Sun head) If you just want to learn Solaris, you are in luck as Solaris x86 is available for free I believe. (I bought my copy for ~$80bucks?). Solaris x86 will most definitely be less forgiving on the hardware support. I feel any BSD, Linux, or Solaris are great starters. Just pick one, and get really good with it. The others will be easily acquired if you run into them. Learn any of them well enough, and you can easily do the two things you mentioned. -integrate UNIX system to the internetwork -use UNIX for device management using scripts Good luck! -Carroll Kong Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=14525&t=14525 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
