setting a vlan on a port [7:45210]
Morning all, I have been trying to set a VLAN on a port on a 2948 but it will not work for me. I have been using set port membership 2/48 100 (with 2/48 being the port and module and 100 being the vlan. It will not accept it for some reason. It will not accept any VLAN actually. TheVLAN in question is on the switch. Am I just being really stupid here? thanks stuart Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=45210&t=45210 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Terminal server required for CCNP/CCIE lab? [7:42600]
Hello, I used to swap the console cable too and was wondering about the same thing, and then I have bought a CS-516 with the "latest" IOS, which is the cheap equivalent of the 2511. If you devide the how many times you plug in and out the console cable till you become a CCIE, you will get something like 0.1c/plug. It is not worth... ;-) But seriously, the good thing which has not yet been mentioned here is that you can have connection to each router in a different window thus seeing in real time what happens on other routers when you change something here... This is extremely useful when you learn... The multiple connections are set up via multiple telnet sessions from your pc to the terminal server and connecting each session to a different router. I also include here the sh ver of my CS516. If you come accross one of these, make sure your OS version is not older than 10.3, which is the latest. This will make sure you will have the same experience then having a 2511.

RE: PIX 515E Question [7:45206]
Actually, now they are included in the 515E-UR for free! You still need to purchase it in the 515E-R models, I believe. This card increases throughput for DES and 3DES to over 63Mbps.

Discontiguous networks ? [7:45220]
Hi group, I set up a Lab to highlight the problem that discontiguous networks brings to distance vector protocols. I seperated three Class B networks (172.16.1.0/24, 172.16.2.0/24, 172.16.3.0/24) with the class C networks (192.168.1.4/30 & 192.168.1.8/30). As expected with RIP 1, I can clearly see network 172.16.0.0/16 being advertised over the serial interfaces, with 'debug ip rip'. I then configured the Lab for RIP 2 thinking that this would be a solution to the problem, since RIP 2 advertises the subnet mask with the network address, but ran up against the same problem as RIP 1. I can solve the problem using secondary addresses, however, I feel that RIP 2 should also solve the problem. Am I missing something here ? Just thinking out loud, should I have put 'no auto-summary' under the rip routing ? maybe it defaults to classful behaviour anyway !!! Appreciate any responses. Phil. __ Do You Yahoo!?

Guys, I am confused out Playing with Different kind of timers in ROuting and switching. Moslty, if we change timers in routing protocols like RIP /OSPF update or hello interval , we must have to change it on both sides of link DOes it mean that when ever we have to change "ANY" timer on one side of interface, we must have to chnage on other side of that link aswell?? like in case of changing timers on IPX rip or nlsp?? 2nd Q is that, To configure IP mobile ARP, do i have to put Bridge group on interface as well??

Re: Discontiguous networks ? [7:45220]
Phil, Without seeing your config, the first thing that comes to mind with your RIP experiment is do you have "no ip classless" on all your RIP routers? Before using "no auto-summary" with RIP, check the notes on your IOS version on CCO. Ver.12.2 specially has features that are new, you'd be amazed what the above command does.

Just as it takes a certain change of mindset to understand what problem BGP is solving, it takes a change of mindset to understand MPLS and the next generation, GMPLS. Many people have problems with the ideas that MPLS does not do away with the needs for routing protocols, and indeed adds new protocols. Also, there tends to be an assumption that MPLS is faster than conventional IP routing, which no longer is the case. There are real values to MPLS, which are more carrier than enterprise oriented. These include traffic engineering/QoS, and extremely flexible failure override techniques that can make link recovery times comparable to SONET. You won't find any Cisco (or other) configuration examples in my new book, but you will see an extensive discussion of functionality--why would you want to use MPLS, and how it changes design approaches (e.g., perhaps no IGP in a large network core). It's a sufficiently rapidly developing field that books will have trouble keeping up with it. The RFCs _and_ Internet-Drafts (see http://www.ietf.org/html.charters/mpls-charter.html ) are still the best references. Don't worry too much about CR-LDP, but pay attention to the traffic engineering and link restoral documents.

Re: How do I approach the company about my CCIE [7:40261]
The JNCIE is a difficult exam, however it is quite realistic. Hence, if you use Junipers in service provider networks and are familiar typical SP configurations, you should have a decent shot at it. The written test itself was designed to be fairly challenging and to compliment the lab and I do recall it being more technically deep than the CCIE written. However, it is also much more focused on a few topics so the increased technical depth makes sense.

The fact that those routers have Read-Only Flash type, doesn't mean that you can't erase and upload a new IOS image. Read-Only FLASH memory requires a different method of "erasing" its contents. The delete and squeeze commands do not apply to them. Cisco's upgrade method for those routers that use Read-Only Flash, includes a couple of steps that will apply a high enough Voltage level to the Flash that will blank its entire content, and then copy the new IOS image in it. Of course, there is a chance that you could have a router with "defective" Flash, meaning that it would not accept new images because its "delete" function no longer works.

Re: Discontiguous networks ? [7:45220]
This looks like a summary issue to me. You should see a RIP advertisement for 172.16.1.0, not 0.0. Of note, the classless and classful behavior are not entirely related to whether or not an update includes the prefix length. Make sure you have ip classless enabled and I would try turning off auto-summary to see if you end up with more appropriate announcements. Of note, with the same prefix length used in your RIP network you shouldn't see any issues with V1 routing. With ip classless off however, you should bump into some issue.

Re: How do I approach the company about my CCIE [7:40261]
Peter I have been following and trading Juniper stock for years. In the beginning everyone loved it because it was so focused - just high end routers. Two things came together in 2000 to help them grow sales 6x over 1999 one was the massive build out of the telcos and the other was the fact that they had a year lead on cisco for delivering 192 interfaces. In 2001 the telco's started cutting back and juniper sales growth went to up 32 %, but all of it came in the first half. Since mid year last year sales have been dropping qtr over qtr. The biggest reason is the same reason the analysts used to love it - focused only on the high end telco market. Well the telco's are in a world of trouble. They are so deep in dept that most will never climb out. Global xing bit the dust and it looks like wcom may follow. Quest is in deep trouble too. Believe it or not the only hope for a recovery in the next year is that these big guys go chapter 11 and then reorg. All the investors get screwed but their debt goes away and they may have some money to invest again. All of the major telcos cut capex for the rest of this year and next in their first quarter report. Juniper's also has to deal with cisco now as they are going after that same market and have taken share away in the last year. This will be especially a problem in markets outside the us where cisco already has a presence and juniper does not. The last two purchases by Juniper say the reconize the problem as they are trying to broaden their product line. But they paid too much for Unishere and it will be dilutive this year. The bottom line is that the big telcos are in real trouble and there is still a lot of competition and excess capacity out there. Their capex spending is going to be the last thing to recover and along with it Juniper. Another good indication is in the job market. Go to dice.com or hotjobs and do a search on jncie and ccie and see what you get for both. >From: "Peter van Oene" >Reply-To: "Peter van Oene" >To: [EMAIL PROTECTED] >Subject: Re: How do I approach the company about my CCIE [7:40261] >Date: Tue, 28 May 2002 08:43:09 -0400 > >What leads you to believe that they "will be at the tail end of the >recovery?" > >At 09:04 PM 5/27/2002 -0400, Wes Stevens wrote: > >Jenny I assume you are talking about Juniper.

RE: how to set duplex and speed on 2500 router int ??? [7:45243]
The 2500 routers don't support full duplex operation. As far as your Sun box, box A appears to be following classful IP rules, automatically assuming that since your first octet is a 61 that your address space is a class A, and therefore your netmask should be 255.0.0.0. I don't know enough about Solaris to tell you how to fix it unfortunately.

Re: VPN Design [7:44953]
Well, have you thought this setup through? I mean... if you are placing the vpn device's external nic in the dmz, and it's internal nic on your lan, you are defeating your firewall. You still have to allow access into the vpn device.(which is the same as having it on the outside) If you really want to have the double protection, you should think about placing the vpn's external nic on the outside and creating a tunnel though the dmz. (of course this also defeats your firewall, but at least you can set the pix to only tunnel from the vpn device) But at this point, it's a trust game. You trust your firewall to protect your corporate lan right? Why would you not trust your vpn device? There's nothing wrong with running parallel firewalls or vpn scenarios. I'm pretty sure I can come up with a list of pros and cons for both. In the end you'll probably find them to be 50/50. Of course, running in parallel may actualy cause issues for your clients on the outside. If the concentrator is not the default route, then you may run into asymetric routing problems. You might try just using one nic in the concentrator too. Unless you are in a scenario that requires high speed routing, chances are, that t1 to the internet is not going to bog down your vpn device. just somoe tidbits to think about. -Patrick >>> "neil K." 05/24/02 11:10AM >>> Hi All, 1. Could anyone please tell me what needs to be done on the PIX firewall if the Cisco VPN concentrator is placed in such a way as the public interface is in the DMZ and private interface on the inside network. 2. This design of placing the Concentraor in the DMZ is a little complex as compared to keeping the Concentrator Parallel to Firewall, which has security risks.Also in the case of Parallel design concentrator public address has to be in the IP subnet as the Firewall and the External Router( If I am not wrong) can this be overcome by placing the Concentrator in the DMZ. 3. Does the firewall need some routing capability so that it can route Encrypted packets to go thru concentrator or can it be done by adding routes to the servers pointing to concentrator. 4.

RE: CCNA level IPX question, proper phrasing [7:45138]
In my opinion that question is fair game. the optional MAC address that can be specified is used for interface that have no bia, such as serial and loopback interfaces. By default they "borrow" the MAC from a LAN interface, but you may want to specify your own in order to keep documentation and troubleshooting simple. For example, if I enable ipx on router #1 using the command 'ipx routing 1.1.1' then all I need to do to ping a serial interface on router 1 that's on network 1a is ping ipx 1a.1.1.1, which is a lot easier than having to look up and type out a mac address. I think that's a great question, and it's certainly a CCNA-level question.

Re: Private Addressing over Distances [7:44946]
You know...I just revamped a class b network (150.150.0.0) that a company had implemented years ago and they didn't own the space. Even though everything seemed to be working properly, the entire 150.150 network was not accessible on the internet.Heaven forbid micrsoft move their hotmail servers to 150.150.x.x. There should be no reason to not do things the right way... :) >>> "Craig Columbus" 05/25/02 01:25PM >>> IMO, it's never a good idea to use public addresses in a private network. The standard response I get when I tell people this is "Well, it's never going to be put on the Internet or connected to another network, so it doesn't matter." But, you should look at it this way: For a given network, there are two outcomes: 1) It will never be connected to another network or 2) It will someday be connected to another network. For small test networks, training networks, home networks, etc., the first option may truly be the case. If so, it is just as easy to assign one of the 10.x, 172.x, or 192.x networks as it is to assign some other IP block that another company may own. At the least, it gets you accustomed to working with the RFC spec private ranges. For business networks, experience tells me that you should always assume that the network will be connected to another network at some point in the future...even if you can't imagine it now. To mitigate problems down the road, a RFC spec private range should be used. This doesn't eliminate the possibility of overlapping private addresses if, for example, you merge with another company that uses the same private block. It does, however, assure that if you hook to the Internet, you won't hit a local server when trying to get to a registered IP address on the Internet. Here's a true story to illustrate the point: I was called in to examine a network that had chronic connectivity problems to points both inside and outside the corporate network. When I looked at the routers, I was astonished to find that each WAN remote site and each subnet had a different public block assigned. Further, there was a spattering of routing protocols installed, including RIP, OSPF, and iBGP, with no apparent purpose or reason. The company had a single Internet gateway that was performing NAT. I pointed out all of the flaws with the installation and design to the company owners who insisted on calling a meeting with the company that had been maintaining the network. We sat down at the table and I presented my findings. The network admin's only defense to his workmanship was "Show me where it says that I can't set things up this way". Needless to say, the meeting was over in less than an hour and I walked away with a substantial contract to fix and maintain the network. I readdressed the network and put static routes in place of the routing protocols. Problem was solved and connectivity was never again an issue. The moral of the story is that just because you CAN do something, it doesn't mean that you SHOULD do something. Craig At 12:52 AM 5/25/2002 -0400, you wrote: >Thanks Craig.

Re: how to set duplex and speed on 2500 router int ??? [7:45251]
What version of Solaris are your running? Do uname -a to find out. bash-2.05# uname -a SunOS ACSNY 5.7 Generic_106541-18 sun4m sparc SUNW,SPARCstation-5 This shows I'm running 5.7 or Solaris 7. Older versions of Solaris only support classful routing and there is no way of changing it beyond upgrading that I know of. Sun calls it variable length sunbet masks or VLSM.

how to set duplex and speed on 2500 router int ??? [7:45238]
Hi Kenny, First, the Cisco 2500 is an old router and doesn't support 10/100, the interfaces are 10BaseT running at 10mbps. The only way round this is to upgrade the router to either a 1700 or 2600 with a fast Ethernet module. Second, try this url for the solaris http://www.enteract.com/~lspitz/interfaces.html There are two sections explaining the configuration of the if on Solaris boxes. There's two things I think you're missing, one you may need a patch on the server to allow vlsm on the hme0 port and secondly I think you're configuring the port under ifconfig which is a temporary measure, in that it will lose the config once you commit a reboot. Load the config using ifconfig, and then edit your file/etc/hostname file so the information will be read on the next startup. I hope this answer the questions you had. Best Regards Andy.

Re: Mail Relay [7:45144]
I think mail relays are to use any mail server to direct your mail on it's final destination. Just like you can use any DNS server on the internet to answer a query, you could send your smtp message to a open relay server to send your mail, especially if you didn't have a server on your network.

RE: Mail Relay [7:45144]
Richard, I assume no one responded since it's not really on topic for the group. A mail relay isn't a Microsoft thing. It's basically any server (MS, UNIX, etc.) that sends mail to another server. Open relays, or mail servers that don't restrict who can send mail through them, are a huge problem on the Internet since they're widely used for spam purposes.

a mail relay is simply any mail server. Your pc is a mail relay when you send smtp traffic to your upstream mail server.

RE: Emergency: HOw to extend the telnet timeout for a router? [7:45268]
Be extremely careful if you configure an exec-timout of 0 0 on a vty port. It will never release! So when you drop the connection and again telnet into the box you now have one less open port. After five times (or number of vty ports) you are locked out of the box.

Re: How do I approach the company about my CCIE [7:40261]
Interesting points. I was of the opinion that you meant the Juniper would be the last of the core players to pull out of the downturn, vs the last of the networking vendors in general. The enterprise hasn't taken as much of a hit as has the SP business which is helpful for those companies that do business there. I tend not to have much faith in market share numbers, particularly when the division between SP and enterprise becomes blurry. For what its worth, I'm not aware of any new initiative on Cisco's behalf to go after the core market. I believe they have had tremendous success in this market in the past wish to continue that success. On the hiring side, I would suggest that I've seen very few service providers use vendor certifications as a guideline in the hiring process. Furthermore, there are less than 70ish JNCIE's and many work for Juniper and thus it would likely be easier to call them individually than mass market advertise for them. I further doubt that many if any mainstream recruiters know about the certification. However, this really is rather OT for this list :) My bad for asking the question I suppose.

Fast Etherchannel is just that: Fast Ethernet (100mbs). There is EtherChannel, Fast EtherChannel and Gigabit EtherChannel. What do you mean by support?

That depends on how you drop the connection. If you type "exit" or "quit" the vty is again available. If you never disconnect, are abruptly disconected or do a ctrl^x then the connection will remain indeffinately.

Ahem. http://www.nanog.org/mtg-0110/lixia.html I know of many instances where this has been used to hijack traffic. It's not just a rumor, this is real. AS3847 used to participate in such overbearing rediculous practices (for fun and profit). Announcing inconsistent routes can also have many operational benefits.

Good point. We have this setup on some of our routers that we commonly just sit in all day, and if I kill the telnet process (without allowing it a graceful exit) my session doesn't hang. it frees up the VTY line I was using.

Re: problem at HSRP [7:45277]
Turn off spanning tree on the switch ports the router lan interfaces are connected to. Also make sure both ports are in the same vlan. Anyways, long and short of it, HSRP is timing out when trying to discover a neighbor due to STP startup time. Also instead of turning off HSRP you could trry portfast.

It really depends on the router, memory and processor do factor into it significantly. We have a 7206 with an NPE-300 and 256M of memory, it has well over 1000 subinterfaces on an ATM OC3, an additional OC3 and a clear channel DS3, no excessive memory or processor usage. -Original Message- From: Steven A.

Re: max number of Sub interfaces [7:45288]
Steven, Every interfaces includes subinterface(sw), physical interface(hw), virtual/logical interface(sw) is divided into s/w & h/w category. Each Software IDBs takes ~2600bytes v/s Hardware IDBs takes ~4700bytes. No.of IDBs you want to use it depends upon your system resources have it currently, going with higher number of subinterfaces may slow down boot process since it has to nvgen configuration, slow-down other processes like "sh run" & saving configuration to nvram may not fit with or without compression, etc... thanks, rahul.

I found the exam to follow the cisco exam outling very closely. For Preparation I used the Sybex book and residual knowledge from CCNP certification. I've almost got the whole set now.

Steven, I supposed it would really depend what else you're doing on the device. I've worked with a pair of 3640s that each had 300 or so sub-interfaces on them, running just EIGRP on the routers and they didn't miss a beat. If each of those sub-interfaces also had crypto running on them, I'm sure that would be another story!!! :) thanks, -Brad Ellis CCIE#5796 (R&S / Security) Network Learning Inc [EMAIL PROTECTED] www.optsys.net (Cisco hardware) ""Steven A.

Re: Fast Ether Channel [7:45271]
Do you have any documents or URLs that talk more about the etherchannel (that allows you to use 10Mbps ethernet in a bundle). I'm not saying I don't believe you, but twice today I've searched Cisco's website to find info on it, and I can't find anything but references to Fast- and Gig-Etherchannel I even did a Google search on 'etherchannel' and of the non-Cisco websites that came up, they still indicated it would only work on 100/1000Mbps ethernet Thanks!

RE: Mail Relay [7:45144]
Hmmm- mail relay is a basic function of most ISP and Web hosting services. Big picture- your DNS name space and map too IP (range) for your SMTP gateway must be listed in or accessible (resolvable) via Global DNS. This allows for the relay downstream toward your exchange server (assuming Microsoft). It all pretty much starts with where your MX (Mail Exchanger) transmit and receive records are pointed and what if any weights are applied in your DNS entries. I have studied this process and actually in the past have had to do a little design work here, but shy of breaking-out the books this is all I can seem to recall @ the moment. Topics for research would be DNS & BIND (specifically MX records), Send Mail, and Exchange (specifically where traffic is received).

Re: Emergency: HOw to extend the telnet timeout fo [7:45268]
If your connection is clean, and the telnet program properly written, it will terminate the TCP session correctly when the program is closed. It's badly written clients, or when your network connection gets cut, or your system crashes that it becomes a problem. In these instances, the TCP session isn't properly shut down. A router with default configuration will never take action to disconnect the hung session. What I typically do is configure a 240 minute (4 hour) timeout. It's long enough to give you time to think about what you're doing, and short enough that if my session is killed by a network problem or an overzealous firewall, I know I'll eventually get back in. There is also another way to deal with the problem - TCP keepalives. http://www.cisco.com/warp/public/471/tcpkeepalive.html Thanks, Shawn Michael Williams wrote: > > Daniel Cotts wrote: > > > > Be extremely careful if you configure an exec-timout of 0 0 on > > a vty port. > > It will never release!

RE: Fast Ether Channel [7:45271]
Mike, Here is a whitepaper on Fast EtherChannel (please continue reading). It talks about Kalpana switches, where Cisco acquired the technology from, and their use of EtherChannel in the early 90s. (look under the title Fast EtherChannel Components, it's in the first paragraph) http://www.cisco.com/warp/public/cc/techno/media/lan/ether/channel/tech/ fetec_wp.htm I don't think there were many Cisco switches that supported EtherChannel. Kalpana switches did (EPS-2015 is one I can think of) and the Catalyst 3000, which was just a Kalpana switch anyway. I bet you could hard set the port speed and duplex on a couple of ports of a 2900-XL or 3500-XL to 10Mbps and setup an EtherChannel group if you really needed to test it. I hope this helps.

Re: Odd thought on HSRP [7:45302]
Chuck, You have a knack for finding simple solutions that nobody else has thought of! ;-) I think it would work to have routers 3 and 4 in your example have a default route to the HSRP address. I can't think of any reason it wouldn't work. The only doc I found that mentioned it was an explanation of why PIM sparse mode doesn't work when doing this, but notice that the doc doesn't say other things won't work: http://www.cisco.com/warp/public/619/hsrpmcast.html Priscilla At 06:35 PM 5/28/02, Chuck wrote: >got to thinking about this for one reason or another. > >fundamentally, we look at HSRP as a means of providing failover from LAN >stations to redundant WAN links, as illustrated: > >wan_link_1 wan_link_2 >| | >router_1 (HSRP MAC/IP) router_2 > |--| > workstations > > > >suppose, however, I have a topology wherein I want downstream routers to >have HSRP protection: > > >wan_link_1 wan_link_2 >| | >router_1 (HSRP MAC/IP) router_2 > |--| > | workstations| > | | > router_3 router_4 > | | >downstream_group_1 downstream_group_2 > >If I were to set the quad zero route to the HSRP address configured for >routers 1 and 2, think this would work? > > >I'm wondering what the implications might be. any thoughts? > >Chuck Priscilla Oppenheimer http://www.priscilla.com Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=45308&t=45302 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Odd thought on HSRP [7:45302]
I worked at an ISP that had many customers with dual Ethernet connections. Some of these customers wanted to do what you described, and it worked fine, as long as the customer configured HSRP so that we could put up static routes to the customer's networks behind their routers using the HSRP gateway as the next hop address. The only issue, and it was minor, was making sure the customer's subnets were advertised to the Internet.

Re: Fast Ether Channel [7:45271]
I appreciate your information, Joseph. I guess my question was more toward the types of interfaces that will run etherchannel. i.e. if you're knocking the speed down on a FastEthernet interface to 10Mbps, it's still a FastEthernet interface, not Ethernet interface. One of the requirements for an etherchannel bundle is that all of the ports (interfaces) in the bundle all be matching speed/duplex. So it would make sense that you could knock 100Mbps interfaces down to 10Mbps (as long as they all match) and it still work. But are they any Ethernet interfaces (not Fast- or Gig-Ethernet) on any Cisco devices that support Etherchannel. I'm thinking there's not, but that's not to say there's not some switch/router out there that may violate this Cisco "rule of thumb" (being you can only do EtherChannel on Fast- or Gig-Ethernet) Mike W.
