Frame Relay BECN [7:42879]
Hi all, Does anybody know how I can see if a 3640 configured as a FRSwitch is marking packets with BECN ?? Is there a debug command or a show (except of sh fram pvc xxx) to see on the routers which are connected to the FRSwitch that the machine is sending back packets with BECN. Try to perform Class Based Weighted Fair Queueing and adaptive shaping with DE-Lists on the routers so that I can match specific traffic (port 80,25 etc.) that can be dropped.

Re: why SFM? [7:42877]
The SMF is basically a 256Gbps switching fabric. The 6000 family has a 32Gbps bus communications system built into it. There are 3 types of cards for the 6000 series. Non-fabric enabled, fabric-enabled, and fabric-only. The non-fabric enabled can only use the 32Gbps bus (to talk to the Sup/MSFC and other cards) and the fabric enabled cards can use the 32Gbps bus to talk to non fabric enabled cards and the 256Gbps switch fabric to talk to the Sup/MSFC, other fabric enabled cards, and fabric only cards. Fabric only cards must use the 256Gbps switch fabric to talk to everything, so if it needs to talk to a non-fabric enabled card, it must to through the Sup/MSFC blade over to the 32Gbps bus The SFM must go into 5 or 6 (or both for redundancy) because that's the only place the backplane of the chassis will accept them (just like slots 1 and 2 are the only places to put the Sup/MSFC blades). Basically all fabric-enabled and fabric-only cards are treated like devices with a 16Gbps connection to a 256Gbps backplane switch. But you must be sure you line cards support it or else they'll simply use the 32Gbps bus. We bought a 6509 with the SFM in slot 5, and 48-port FastEthernet blades in the rest (well, slots 12 had Sup2/MSFC2s), but our so-called Value Added Reseller didn't realize when he placed the order that the ethernet blades he got were NOT fabric enabled, so now we have 288 FastEthernet ports on a 6509 w/SFM and NONE OF THEM can use the 256Gbps backplane it's just sitting there dormant. what a waste and what a dumbass VAR for not realizing what he was doing!!! If your're going to be switching alot of Gigabit connections, get the SFM. and be sure your blades are fabric-enabled! After all that, here's an URL that describes in-depth how the 6000/6500s work with and without the SFM.. good info http://www.cisco.com/warp/public/cc/pd/si/casi/ca6000/prodlit/k6kfy_wp.htm Mike W.

Re: ways to seperate IP and IPX traffic? [7:42855]
This is how I used to setup 3com 3500's. They could not do wire speed ip/ipx if they were on the same interface. so for every layer 3 network, you would actualy have two interfaces. Both of which would go back to the same vlan on the core switch. of course, at layer two, all the frames are still traversing the same equipment, so unless you are using older gear (such as the 3500) it's kinda silly to set things up that way. Unless you just want to compare port utilization for ip/ipx...? And sniffer pro does that quite nicely... :) my $.02 -Patrick Chuck 04/29/02 09:06PM in the old days of vlan switching, there was serious discussion of using vlans to separate traffic by protocol. set up ports 1,3 and 5 as IP and ports 2,4, and 6 as IPX.

Re: ways to seperate IP and IPX traffic? [7:42855]
Sounds like your novell admins just use compaq smart start and leave things at defaults. (novell WILL destroy a network if not configured properly) The tree is constantly updated. (putting your novell network on it's own l3 net also helps out a lot! And across WAN links? Forget it! If you have servers at remote sites, updates to the tree should be done at off peak times. (but don't think MS and active directory is going to fix any problems. It's worse across WAN links than novell! constantly pushing and pulling garbage! And let's not even go there with SMS... Ever take a trace of a poorly configured sms install? woowee... I see an average of a 2% traffic increase when migrating to active directory over a standard nt domain. (and 2% of 100mb is nothing and on a lan is not bad at allbut take that same percentage and bounce it across your wan links and you start to bog down!) (and I don't push novell or microsoft...if I push anything, it's linux/unix :) ) I just don't believe there is one best answer... all the nos's have their flaws and their strong points. -Patrick long live netbeui Michael L. Williams 04/29/02 11:17PM Priscilla Oppenheimer wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... AppleTalk traffic doesn't bother other people. AppleTalk devices don't broadcast; they multicast, and they don't do that very often. AppleTalk routers and servers don't ever broadcast (or multicast) service announcements like they do in an IPX environment. And the Chooser doesn't broadcast either. A Mac sends a unicast packet to a router when the user pulls up the Chooser. The router figures out which networks are in the zone and forwards the unicast. The recipient routers then multicast. And, no, this doesn't repeat forever at short intervals. Since Mac OX 7.0 (1989) the Mac has backed off on the unicasts it sends to start the process. Okay...at the risk of facing the wrath of Priscilla, here goes. =) Just off the top of my head, why would multicasting be any better than broadcasting in fact, wouldn't that be worst as broadcasts (L2 or L3) are stopped at the router whereas multicast could traverse your entire network, even through routers...? You gotta give me this tho: AppleTalk picks a layer three address at random, then checks to see if it's in use and repeats until it finds one it can use. How lame is that? I was digging thru my CCNA notes from 2+ years ago and read a comment I wrote saying (about it choosing an L3 addr at random) imagine if that were used on the internet... it could take days/weeks to get an IP address.. =) You knew you would push one of my buttons, didn't you? ;-) As far as IPX traffic, it's not really that bad either, but the SAP broadcasts can get excessive. There are many ways to keep them contained, if that's what the poster had in mind. I think he better give us more info on what he's trying to accomplish. I have to disagree here... IPX traffic is horrible (admittedly due to Novell, not as a protocol itself per se. also as you pointed out, in all fairness, a large %-age is SAP broadcasts and admittedly, the people whom I inherited the network from didn't do squat to limit any kind of SAP traffic). If you pick a random switchport out of the 28000+ switchports on our network and do a sniffer capture, you'll find probably 75% of it is IPX related... and we use IP for probably 90% of our apps (and web/internet access). that's not acceptable. we cannot wait to get rid of IPX altogether (which will happen when our migration from Netware to 2000 is complete). I'm not a Microsoft zombie, by any means, and I won't even claim that Win2K and Active Directory is any better than Novell NDS, but getting rid of IPX is a godsend no matter if it means running Microslop Win2K that's how much we hate dealing with IPX =) Hopefully he didn't just buy into the BS that IPX is chatty (the same BS that you hear about AppleTalk. ;-) You want chatty, watch a Windows machine running NetBIOS and SMB boot! Sounds like sour grapes. LOL (just kidding =) Hey I've seen your website with you @ your I-SCHMAC laptop so it doesn't surprise me to see you defending AppleSquawk... =) Mike W.

frame-relay interface-dlci issues. [7:42902]
Just a quick heads up to a couple of problems I had over the weekend on the Solie scenarios. Anyway one the routers needed to be set up a having two sub interfaces, one point-to-point, one multipoint. On the PTP I mapped the wrong DLCI to it and even though I removed the statement and rebooted, it would not remove it. I needed to remove the subinterface and reboot then recreate the subinterface with the correct DLCI. Also I had a problem with another DLCI not being seen by the spoke router. This router's serial interface line protocol was also going up down. I suspected missing LMI and that was the case. It turns out that in recabling for the new lab, I bent one of the pins on the serial over. Anyway these two things cost some time so if I can save anyone grief with similar problems great. Otherwise I learned a few things which is the whole point of this.

It depends. What interface does the CSU/DSU have on the Telco (they say network side)? Most CSU/DSUs have an RJ-45/48 jack. Some like Larscom have a DB-15 connector. Yes - you can buy adapters to make it an RJ-45. Not fun to learn on a Sat AM. How long will the cable be between the CSU/DSU and the SmartJack? If a short distance, then Cat5 will do. Pins 12 and 45 straight. Some cable vendors sell a shielded cable (T-shield?)(Think that it is two pair.) to protect the cable from electrical fields. Ground the shield at one end. There are other larger shielded cables used to run multiple T-1s in one bundle. These are preferred for longer runs. -Original Message- From: sam sneed [mailto:[EMAIL PROTECTED]] Sent: Tuesday, April 30, 2002 10:59 AM To: [EMAIL PROTECTED] Subject: CSU/DSU cabling [7:42897] I'm installing a 2600 series router a remote location and wanted to double check on the wiring.

debug output [7:42909]
I've been trying to set up RIP load balancing, and although I have two equal-cost paths, show ip route only shows one of the paths. When I debug ip packets, I notice the the len parameter's value is different for the two serial links to the target network. The output looks like this: IP: s=192.168.3.2 (Ethernet0), d=10.0.0.1 (Serial1), g=192.168.2.1, len 72 ... IP: s=192.168.3.2 (Ethernet0), d=10.0.0.1 (Serial1), g=192.168.1.1, len 52 ... As you can see, the len vlaue is different for the two paths. I should note that the target Ethernet network runs between a 2621 and a 2514. My questions are what is the len parameter? Is the difference in the values responsible for my inablility to load-balance? And can the len be modified? Thanks in advance for any light you can shed on this. I've searched the archives and the Cisco site, but I've been unable to find anything directly on point.

in defence of IPX, AppleTalk, and IPv6 stateless autoconfig [7:42913]
It doesn't surprise me that 75% of the traffic you see when you put a Sniffer on a switch port is IPX. It's probably SAPs and RIPs. Remember that you only see broadcasts unless you mirror other ports. So you may be getting a skewed view. Regarding your comment about multicasts: A good driver will register with the NIC to receive only those Layer 2 multicasts it cares about. So a good NIC and driver on a PC that doesn't understand AppleTalk just drops AppleTalk multicasts. Routers don't forward these multicasts. Even routers configured for AppleTalk don't forward them. They are Layer 2 multicasts. Regarding AppleTalk's dynamic addressing, sorry that you think it's lame. The IPv6 developers don't. Their stateless autoconfiguration if very similar. comments below). Regarding your CCNA comment about obtaining a unique address with AppleTalk, it doesn't take many packets to get a unique address is most cases. For one thing, a device uses the one that it used last time it booted. It's unlikely some other device would have taken the address in the meantime on a well-designed network. Now, I would like to turn this into a teaching moment. ;-) Here's how IPv6 stateless autoconfiguration works. If you know AppleTalk, you will see the similarities. This is from my upcoming book. Stateless autoconfiguration requires no manual configuration of hosts, minimal (or no) configuration of routers, and no servers. For a network engineer who is not concerned about which addresses are used, as long as they are unique and routable, stateless autoconfiguration offers many benefits. Stateless autoconfiguration is discussed in RFC 2462. With stateless autoconfiguration, a host generates its own address using locally available information plus information advertised by routers. The process begins with the generation of a link-local address for an interface, which is generated by combining the well-known link-local address prefix ( 1110 10) with a 64-bit interface identifier. The interface identifier is usually derived from the hardware address in ROM on the NIC. The next step determines the uniqueness of the tentative address that has been derived by combining the link-local address prefix with the interface identifier. The host transmits a Neighbor Solicitation message with the tentative address as the target address. If another host is using this address, a Neighbor Advertisement is returned. In this event, autoconfiguration stops and some manual intervention is required. (Because the address is partially based on a NIC address, duplicates are very unlikely.) If no responses are returned, the tentative address is considered unique, and IP connectivity with local hosts is now possible. Before sending a Neighbor Solicitation message, an interface must join two groups: the all-nodes multicast group and the solicited-node multicast group for the tentative address. The former ensures that the node receives Neighbor Advertisements from other nodes, the latter that two nodes attempting to use the same address simultaneously detect each other's presence. To check an address, a node sends Neighbor Solicitations with the IP destination set to the solicited-node multicast address of the target address. The final phase of the autoconfiguration process involves listening for Router Advertisement messages that routers periodically transmit. A host can also force an immediate Router Advertisement by transmitting a Router Solicitation message to the all-routers multicast address. Router Advertisements contain zero or more prefix information options that contain information used by the host to generate a site-local address that has a scope that is limited to the local site. The router advertisements also include a global address with unlimited scope. The advertisement may also tell a host to use a stateful method to complete its autoconfiguration.

AppleTalk devices don't broadcast; they multicast, and they don't do that very often. AppleTalk routers and servers don't ever broadcast (or multicast) service announcements like they do in an IPX environment. And the Chooser doesn't broadcast either. A Mac sends a unicast packet to a router when the user pulls up the Chooser. The router figures out which networks are in the zone and forwards the unicast. The recipient routers then multicast. And, no, this doesn't repeat forever at short intervals. Since Mac OX 7.0 (1989) the Mac has backed off on the unicasts it sends to start the process. Okay...at the risk of facing the wrath of Priscilla, here goes. =) Just off the top of my head, why would multicasting be any better than broadcasting in fact, wouldn't that be worst as broadcasts (L2 or L3) are stopped at the router whereas

Trying dropping some DE bits (different than Bacon Bits, which incidentally aren't terribly good for your skin anyway) in the tub, then configure your soap to forward FECN and BECN bubbles in the appropriate directions.

If you have an SLA (Sludge Limit Agreement) with your ISP and they are in fact in violoation of the SLA, you can demand remuneration for time lost waiting for queue flush.

How is that different than IPX? It seems if you are going to increase the size of the address enough to include the MAC address, assigning a unique (whether locally or globally) become trivial. After all, MAC addresses are, in thoery, globally unique. Then the only question is routability, which means network information picked up from the line (as in IPX) or from a server (in IPv6 as you seem to indicate in your post). My greatest concern about IPv6 (and this is probably due to my ignorance on the subject) is the apperent reliance on name resolution. I just think how oftern in my line of work it is easiest and most expedicious to use the IP address rather than the name. That isn't going to be feasible when the address is 60 odd characters long.

Re: ways to seperate IP and IPX traffic? [7:42855]
to add to Priscilla's comment; locking down frame types is absolutely a must! And remember if you have two frame types bound to any interface, in order to route, you must have both frame types on the router interface. Otherwise only the original frame type will get out. (which in some scenarios is done on purpose) And if you do have a reason to use multiple frame types, remember you double the saps and double the load on your router. Even if two devices are on the same layer 2 segment, they will not be able to communicate with one another without sending every packet to the router. (only to have it sent right back down the same pipe to the dest. device) -Patrick Priscilla Oppenheimer 04/30/02 02:57PM At 01:50 PM 4/30/02, Patrick Ramsey wrote: what?

That is exactly the way I would do it. In fact, it's probably the only way to accomplish your goal. One additional thing to consider is assisting your client with a migration to 100% IP.

He is going to add some servers to the network, but dosen't want IPX on that new network at all. And he only wants selective IP machines talking to the servers. What I think I'll do is just create 2 Vlans, 1 for the dual IP/IPX machines and 1 for the IP servers. If a dual IP/IPX machine wishes to speak to an IP server, they'll have to use IP and be routed over via a L3 device. I just want to make sure that the IPX traffic/babble dosen't leak onto the IP only network somehow just because they're on same switch.

Re: Since you are in a teaching mode... [7:42913]
Also.. (I need to re-read your post to get a better understanding of the mechanism in IPv6)... how will self-allocating addresses affect summarization.. part of what's killing BGP/internet routers is that addresses are scattered around and makes the table much larger than what it should be. If the lower order bits were based on MAC addr, it seems that there would be a huge waste of address space.. i.e. if the MAC addr of a NIC is used as the last (least significant to everyone but IBM) 48 bits, wouldn't that mean the smallest scope would contain 2^48 addresses (i.e. the first 80 bits are assigned and the last 48 are MAC based) which is 65536 times more than all IPv4 IP space combined. So when Joe Blow opens a couple of furniture store and puts 5 PCs in, he'll have 2^48 addresses assigned because that's the smallest scope? I'm way off in speculation land at this point. so feel free to publicly humiliate me to set the record straight =) I'm sure I'm missing something and I need to read and learn more about IPv6 (when's your book coming out? =)... however, it seems in an attempt to make addressing a convenience (where it doesn't take skill to understand and do it), there will be wasted space.. The only people that want auto-addressing, IMHO, want it out of laziness... I mean, technologies like DHCP can handle dynamic assignment of addrs from a given scope, so why concentrate on fixing something that's not broken. Why bother wasting time with convenience of auto-addressing and just fix what's wrong with our system now (i.e. it's 32-bit which the 128-bit will fix, and the fact that IPs weren't handed out in a way that was condusive to summarization, which can be fixed when they start handing out IPv6 addrs) Mike W.

application-oriented network design [7:42933]
I'm reading Priscilla's Top-Down Network Design. I recommend it as a complement to the Semester 7 BCMSN books. Is there a design strategy or methodology that I can use to diagram application layers into the logical topology? The application I have in mind is AVVID. Suppose the implementation was to take place in two phases: integration of data and IP telephony in phase I, adding video conferencing in phase II. Suppose also that the design included several VG200's and the MCS 7800 (either 7825-800 or 7835-1000), also a switching backbone consisting of 6509 switch with supervisor engine in module 1 and 48-port IP phone blades in modules 2, 3, etc. Phase I would use external 2600 routers; in phase II routing would be moved to the 6509, keeping one or more of the 2600's as backup. Is there a standard technique for incorporating AVVID applications such as this in the logical and/or physical network diagram? I'd especially like to find a template of the logical components and how they interact with each other. That might help explain how to select the hardware and software, and where to locate them in the logical and physical topologies. -- TIA, TT Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=42933t=42933 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: application-oriented network design [7:42933]
I've done some of the larger designs and installations of AVVID in the world, and especially North America, so let me know exactly what you need. I'm not badmouthing Cisco, but they config a lot of the AVVID stuff wrong, and they invented it! Cisco is good at data implementations, but it's hard to find a good guy in the field who can give good advice on the configs and HW involved. Basically, the AVVID server components go where any other server goes. VG200's go where ever as well, but keep in mind there are two types, the Vg200 gateway and the Vg200 DSP farm. As for implementing the voice first and video second, keep in mind, once you have a good, solid data infrastructure in place that can handle QoS, the video phase is quite easy. Bandwidth over the WAN may be your biggest issue at that point. Tom Scott wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I'm reading Priscilla's Top-Down Network Design.

I realize 128 bits is alot of bits now. but I also remember when 640K was alot of memory (no one will ever need more than 640K) I remember when 32-bits of address space (IPv4) was considered endless, so why bother conserving address space, etc. and now look at where we are Now we have to use NAT at every turn to reuse 10.x.x.x and 192,168.x.x on private and corporate LANs because real IPs are so scarce. Now ISPs give you the 3rd degree, mounds of paperwork, and many times request usage details for you to justfy that /26 they allocated to you These problems could have been avoided with IPv4 with better address management and allocation ( I mean, MIT and IBM both have their own /8s... neither organization could dream of using all 16.7 million of those addresses that equals major waste)... but again, that was back when 32-bits was alot of bits. so we shouldn't view 128-bits as a lot of bits for that matter, IMHO, we should treat every new address as a precious commodity as we do IPv4 addresses now..

Great... but ability to be aggregated means nothing if the addresses are discontiguously allocated (i.e. are allocated in a manner that isn't condusive to aggregation), as is the case with IPv4 currently. If IPv4 addresses were allocated properly, BGP routing tables would be 4MB, not 128MB. I know you understand allocating addresses in a manner that makes summarization possible, and you know there are ways to assign addresses (poorly) that keeps an adminstrator from being able to summarize. So even tho IPv4 (and IPv6) support aggregation, if allocated improperly, the aggregation feature vanishes..that's all I was saying The only people that want auto-addressing, IMHO, want it out of laziness...

(perhaps they could just be embedded like MACs are)... You made fun of AppleTalk, but there is an IETF movement afoot to standardize user-friendliness, autoconfiguration, and many other AppleTalk themes. See the work of the Zero Configuration Networking working group here: Hey! I wasn't making fun of AppleTalk. just pointing out things I thought were lame =) I can't really explain it... it's just a nagging feeling. oh... that's just my dog pulling on my pants leg =) But, it seems to me that, even on Macs, if AppleTalk were that easy to setup/use and administer, then why has TCP/IP pretty much crushed it (along with IPX, etc)? I guess my point is, ease of configuration and user friendliness, although niceties, will always take a back seat to core functionality and compatibility. And any sort of autoconfiguration isn't worth the price if it autoconfigures at the expense of proper address allocation. Also keep in mind that the Zero Configuration Networking, no matter how well thought out or planned, will be just like any other Zero anything (i.e. Zero Effort Networking (Z.E.N.

Re: Since you are in a teaching mode... [7:42913]
Let me make some general comments. I think people are missing some of the fundamental architectural concepts of IPv6. Indeed, I was one of the people in the final vote (well, consensus) at the Toronto IETF where we decided on 128 versus 64 bits. It is NOT the intention of IPv6 to expand the address space so that everyone can have their own static address. Addresses have two distinct functions that coexist in IPv4, but that IPv6, not completely cleanly, tries to separate. These functions are location and identification. Location is routing-oriented and tells you how to get somewhere. Identification identifies a specific host or interface. In very general terms, the high-order 64 bits of a v6 address are used mostly for location, to reach a particular scope called a site. The next 64 bits identify (potentially with levels of aggregation), hosts within that site. Again simplifying greatly, renumbering to a new carrier requires you to change the locator but not the identifier. Moving a host within a scope may require you to change the identifier but not the locator. There are some forms of multihoming that aren't completely solved, and the multi6 Working Group is trying to come up with strateies. The high-order locator part has at least three levels of aggregation for public addressing: Top-Level Aggregator, Second-Level Aggregator, and Next-Level Aggregator.

Absolutely, positively, the architects intended to waste some space to avoid some of the convolutions we go through with V4. So? 128 bits is a lot of bits. In fact, there's more waste than you may realize. In a number of the formats, Interface IDs are required to be 64 bits long and to be constructed in IEEE EUI-64 format. EUI-64 based Interface identifiers may have global scope when a global token is available (e.g., IEEE 48-bit MAC) or may have local scope where a global token is not available (e.g., serial links, tunnel end-points, etc.) So? Isn't it dangerous to approach a new technology (128-bit addressing scheme) with such a ah, who cares if we waste there's so much attitude? I realize 128 bits is alot of bits now. but I also remember when 640K was alot of memory (no one will ever need more than 640K) There was some fairly extensive analysis done to suggest that we have to get considerably off the planet before 128 bits turns out not to be enough. I can't cite the specific RFCs, but they are among the V6 documents. Also look for a couple of RFCs that talk about the H ratio for address space. I remember when 32-bits of address space (IPv4) was considered endless, so why bother conserving address space, etc. and now look at where we are Now we have to use NAT at every turn to reuse 10.x.x.x and 192,168.x.x on private and corporate LANs because real IPs are so scarce. Now ISPs give you the 3rd degree, mounds of paperwork, and many times request usage details for you to justfy that /26 they allocated to you These problems could have been avoided with IPv4 with better address management and allocation ( I mean, MIT and IBM both have their own /8s... neither organization could dream of using all 16.7 million of those addresses that equals major waste)... but again, that was back when 32-bits was alot of bits. so we shouldn't view 128-bits as a lot of bits for that matter, IMHO, we should treat every new address as a precious commodity as we do IPv4 addresses now.. Regarding IPv6 autoconfiguration addresses, I'm no expert. You'll want to read the RFCs to answer those questions. But I think your fears about summarization are unfounded. RFC 2723 says this: IPv6 unicast addresses are aggregatable with contiguous bit-wise masks similar to IPv4 addresses under Class-less Interdomain Routing [CIDR]. So that RFC2723 is saying is that IPv6 has the ability to be aggregatable like IPv4 under CIDR. Great... but ability to be aggregated means nothing if the addresses are discontiguously allocated (i.e. are allocated in a manner that isn't condusive to aggregation), as is the case with IPv4 currently. You may be missing that the high-order (itself subdivided) and low-order parts are assigned separately. One can change without affecting the other, in most cases. If IPv4 addresses were allocated properly, BGP routing tables would be 4MB, not 128MB. No, probably not, because we see the trend that users want to multihome in a manner that simply is not conducive to aggregation. Other schemes are being discussed, such as scoping the propagation of announcements up to, but not beyond, a point where providers peer and the individual
