Can ping gateway from Catalyst RSM, but can't ping RSM from [7:16775]
Hello all, I'm having some trouble with a Route Switch Module on a Catalyst 5500. I have set up an IP on the vlan1 interface on the RSM. On the same subnet, I am able ping hosts from the RSM, but I cannot ping the RSM interface from the gateway, or any other hosts for that matter. Can any help? My config: Building configuration...

RE: Help! Locked out of my 7513 Router! [7:16769]
i Had this happen to me. My symptoms were you could execute the break sequence but the rest of the keyboard is unresponsive. whether trying to break into the router or normal console as i could see the boot up sequence when reset. This happened with 2 of my routers. So i used another computer and was able to console in with no problems. i put it down to my serial ports or UARTS on the serial ports of the PC had gone on the blink.

Partner Specialization exams - how tough? [7:16773]
Hi all, Can anyone provide feedback on the partner specialization exams? In particular, I'm interested in the Field Engineer and Systems Engineer exam for wireless LANs. On the scale of "regurgitate these marketing factoids to win a free t-shirt" to "CCNP", how tough is this guy? Any idea of how many questions and how much time is allowed?

-If you think the config change made the mess, try to boot with slot 4 removed. -Also, are you using the right break key for your hyperterminal?

Dear Cisco Groupstudy Person: I locked myself out of my Cisco 7513 router somehow.My Keyboard has no effect. I'm not sure if this is the reason, but my most recent configuration change was to fill the No. 4 slot, previously blank, with a Fast Ethernet Card. Everytime I power cycle the router, it comes up again, goes through the boot sequence, and then freezes with a string of messages concerning the status of FE 3/0 and FE 4/0, first stating that they are up and then stating they are down. Even the password recovery technique where one uses the "Break" or "^[" Keys and then resets the Config Register can't be used. For some reason, the keyboard won't even work; it has no effect in this situation suddenly!!. I have carefully checked my Hyperterminal settings of 9600 baud ; Data bits=8 Parity=none stop bits=2 Flowcontrol=none Anybody have any idea why my keyboard is "dead" I am working with Vlan configurations on this Router.

Re: CHALLENGE PROBLEM (was Re: For FR Grus.... [7:16635]) [7:16768]
Sounds like Spanning tree is screwing it up. Since this is a multipoint interface. It think spanning tree will consider it as one port. Any packet that comes in the router and is destined for the same subnet doesn't hit the BVI and is bridged. 1st rule of bridge forwarding : If the destination MAC address is unknown, forward out all ports except the ingress port. Since all the packets come in the same port as far a spanning tree is concerned, unknown or ANY packets for that matter, will not be set out the same port. Packets on different subnets hit the BVI and are routed and so will bypass the bridging rule. A bridge will NEVER forward a frame out the same port in came it. Solution: Set up P to P subinterfaces. These should be treated by bridge as different ports and frames will get forwarded. IGRP and split horizon have nothing to do with it.

RE: A new networking term - thoughts? [7:16668]
You were, you were, but that was not my point. My point was that Split Horizon 'splits' the 'horizon' the routing update came from, from the outgoing 'horizon' the update is forwarded out through. On iBGP, it doesn't propagate it out to any (unless again it's a cluster server) so the term Split Horizon would be incorrect to use here. I would rather call it No Horizon, or something similar but different than S.H.

RE: HELP!! The Cisco Code & Windows XP [7:16604]
the research I did in thinking about this question a bit more deeply led me to the 802.1x port authentication issue. is it correct that Microsoft turns on everything under the sun by default, and leaves it to the befuddled LAN admins and bedeviled help desk and desktop support people to figure out why things all of a sudden are broken?

The Cisco Code & Windows XP [7:16604] I wish that Networking 101 was required in schools. Then even the Management by Business Week types would know about the 7 layers and that the operating system, which generally deals with local file management and I/O, should not matter when considering traffic going through routers and switches. In actuality, there may be issues because the TCP/IP stack and other protocols are part of the operating system and they could be buggy, but if they are standard and not buggy, then there shouldn't be an issue. I don't mean to flame the person that asked. It can't hurt to do some research, and there was that one bug with 802.1x security and Catalyst 5000 switches connecting PCs running Windows XP, but that kind of thing shouldn't happen. On the other hand, both Cisco and Microsoft like to take simple concepts (like bridging, etc.) and make them so complicated that bugs are bound to happen. We run an ISP among other things. I wish that our users would take the basic networking class also. This morning someone called and said she had an error message about running out of server space. So I talked to her about not keeping mail on the server. She said, "you mean I can't keep messages in my In Box?" Sigh. Networking 101 would have a short section on client/server architecture too.

RE: HELP!! The Cisco Code & Windows XP [7:16604]
I did a little more checking on this. there is a known issue with XP clients and Catalyst 5000 switches with EARL 1 and certain software revisions. I may be misunderstanding this completely, but it is an issue with the interaction of the Cat 5K and XP when 802.1x port authentication is enabled. that got me to reading on 802.1x authentication. interesting.

I do know that I've heard the term "split horizon" in this context before. I agree that we should probably use it more often. A slight modification might be that a BGP speaker will ignore updates that include its own ASN in the path. I don't know if that still qualifies as split horizon since it's the receiver of the route that is disallowing the update, not the sender (as in the case of split horizon in other protocols.)Still, the end result is the same and I think it applies.

I thought I was fairly careful in stating that with iBGP split-horizon, an iBGP router will not advertise a route to the same AS from which it receives the route. This covers the interface issue.

[7:16668] Chuck, I think there's a difference here. Split Horizon as you say, does not advertise a route back out the interface that it received it on, but the iBGP does not only not propagate a route learned from other iBGP out the receiving interface, but it does not propagate it out any interfaces unless it has been setup as a cluster server.

Re: DHCP on Ethernet interface [7:16746]
24.65.134.40/23 of course should fall in a range of: 24.65.134.1 to 24.65.135.254 which puts your gateway out in left field someplace.. :-) If you connect a "supported" device for testing - just a Win95/98 PC, do you get the same IP parameters? If you get the same stuff then "perhaps" Shaw will continue talking to you. Did you ever have a PC on this before or is it a new circuit? In any event, it doesn't justify the behaviour - that's the problem if there isn't enough competition. Maybe Sympatico HSE is available in your area?

Re: Promiscous interface and remote users [7:16734]
If there's a risk that John Doe could gain access to the NT and Unix systems where the sniffer software is running, then this does seem very unsafe. It would be better to run sniffer software on a machine that is not capable of supporting multiple users and doesn't support remote access. Sniffer users that know what they are doing can learn a huge amount of information, including passwords, confidential data, etc. Both FTP and Telnet use unencrypted passwords. This may not seem like a big deal except that many people use that same password for access to confidential database files. In addition to passwords, the sniffer user is going to see realms of other data that could be confidential. (Once while teaching an onsite Sniffer class, I noticed that an executive for the company was printing a contract to sell the company.) Running sniffer software on a shared machine is asking for trouble unless you are really sure a hacker isn't going to get into that machine.

If you do, then you're one up on Shaw Cable's technical support. They won't look at the problem because it's a Cisco router at the other end--an unsupported device. But the device isn't the problem--their scope configuration is. No, I can't get any information on who it is that I'm speaking with other than his name is Darren. No, I can't speak to a supervisor. And no, I can't continue talking either because I've just been hung up on. What excellent customer service. Just what exactly is technical support for?

Re: Load balancing [7:16738]
You could run load balancing by pointing two default routes on router A, onde to it's ISP and another to router B. Make sure both have the same administrative distance. To make router B take over when router A fails, use HSRP (Hot Standby Routing Protocol) so router B will become your default gateway when A fails.

RE: CAR, is it a decent solution? [7:16737]
The way I understand it and when I used it in our lab environment CAR works good. You can rate-limit per IP, IP block, or all traffic as an aggregate. DCAR is where the processing is distributed to the VIP. So I don't see how a 2600 could use that. Of course on an interface that use a VIP card, if you go into the interface itself, you can tell it to use only cef and not dcef by typing ip cef only. Car can rate-limit using access-list which the rate-limit can references. You can also create a "access-list rate-limit". CAR uses the token bucket scheme. There is one bucket for each list, unless you use the continue option, then your flow may match several limits. You can set the TOS bit or IP precendence with CAR as well. You can make it so that the flow compared to one rate-limit then continues on to as many other rate-limits as you would like. The key I think to CAR is to remember that the rate-limit looks at the flows, but acts as an aggregate.

Promiscous interface and remote users [7:16734]
Hi, We have 2 sniffer systems on NT and on Unix. The sniffer puts the ethernet interfaces on both the systems in promiscuous mode. Currently we are not worried about any local users on the system. Are there any threats from remote users on the promiscuous interface, on either system? When I say "remote users", I am talking about John Doe on our network who has no business with either of these system. John Doe could be on Internet as well but has no user accounts on these systems. Would he get any vulnerable information from the sniffer interfaces on either system?

CAR, is it a decent solution? [7:16732]
I was wondering if anyone on the list has had experience working with CAR in a large environment. How well does a 2600 handle 20 seperate rate limited IP blocks? How well does distributed CAR work? How does it perform, and does it cause a problem with any other things running on a router? Thank you in advance.

Why would you do this? Well, in early DSL rollouts, things on Cisco routers like IDB's, BVI's, etc were limited resources..some routers could only do 300 even. So you would lump many DSL customers in on one multipoint interface. > I think in the given senerio, it should be configured > as point to point network. Yes, ideally, but its sort of like a typical Cisco or CCIE type problem, where the configuration is valid, but doesn't necessarly make sense or would be the best way to do it.

August 25th Washington DC Router Roast [7:16723]
Dear Friends, We will be holding the Cisco Professional Association - DC August meeting and picnic on Saturday August 25, 2001. Because the ceiling in my living room is finally getting fixed, this being 7 years after the tornado damaged our roof, we are NOT holding this meeting at my house. Bob Lowery ([EMAIL PROTECTED]) has graciously offered to host the August meeting at his house: 6661 Mohawk Ct, Columbia, MD 21046 Directions and Map are available from www.mapquest.com The meeting will start at 10 am. Lunch will be around noon. Meeting ends at 4 pm. Our guest speaker this time will be LT. Benedict Eu, PhD, who will be discussing the recent Networkers conference, including such topics as the CCIE Power Session. As part of the day's festivities we are doing a Cisco Swapmeet. Bring stuff you want to sell and a list of things you'd like to buy. Bob also says that he has a bunch of Cisco gear that just came in which he is offering for sale. Should be great for those of you trying to build your Cisco home labs. As per usual, please bring yourselves, laptops, etc. We will be doing hands-on labs in the afternoon. Please bring Sodas, Snacks, and Dessert foods to share! You are all hereby invited, see you at the Router Roast! Yours Truly - Bruce Evry, CPA-DC PS - we are going to offer Basic Cisco (ccna level) courses to help get more equipment for our Lab here, if interested please send E-mail to [EMAIL PROTECTED] (after we get more equipment we'll go on and do higher-level stuff!)

books on PIX? [7:16720]
Anyone know of any good introductory books on PIX firewalls? Something nice and simple that has a beginning, middle, and an ending.(Most authors of tech books miss this concept). I'd rather not have to jump around in CCO land getting snippets of different functionalities that I probably would never have to implement. Just the basics. Thanks.

If the clients are on different layer 3 network, then that should be configured as point to point network. If they are on same network then they can use point to multipoint. I think in the given senerio, it should be configured as point to point network. Arun --- Brian wrote: > No one has gotten this problem yet.

YES! You got it correct! One must remember that when bridging on a router, its just like a real bridge/switch. Interfaces are like ports on a bridge, and a packet entering a port will never go back out that same port. Using sub interfaces fixes it. Now why does it work when you put them on 2 different layer3 networks? Because this forces packets to tag the BVI, and thus get routed (BVI must be setup with secondary addressing). And routing can go out the port, tag the BVI, and go back down the port, but bridging will not work! > (This limitation is intended to avoid bridging loops, I think, because > STP will treat physical interface as a single bridge port.) > > The common solution is the use of p2p subinterfaces.

RE: What Router for Routing Between VLANS [7:16609]
Ole forwarded this link to me. It appears that Cisco has indeed released a FastEthernet Network Module for the 2600 series. It must have come out fairly recently. http://www.cisco.com/univercd/cc/td/doc/product/access/acs_mod/cis2600/hw_inst/nm_inst/nm-doc/connteth.htm#34411 Now that these are available, I may use a couple in the near future. Regards, John >>> "Leigh Anne Chisholm" 8/21/01 10:41:33 AM >>> I just checked the 2600 product catalog. It doesn't list a FE for the 2600... but it does list an NM-4E (4 10 Mbps Ethernet interfaces) which would enable you to route between four... er... um... oh heck. Between 4 VLANs. Sorry Peter, I couldn't think of another way to explain it on short notice! (-: -- Leigh Anne -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of John Neiberger Sent: Tuesday, August 21, 2001 9:40 AM To: [EMAIL PROTECTED] Subject: RE: What Router for Routing Between VLANS [7:16609] This really confuses me because according to the Cisco products reference guide, there is no FastEthernet module available for the 2600 series.

RE: CHALLENGE PROBLEM (was Re: For FR Grus.... [7:16635]) [7:16714]
I can think of two reason why it wouldn't work. 1. Because you're using bridging on the frame relay links, it must adhere to the spanning tree rules. This means that you cannot send traffic out the same interface you receive it on. In this configuration it would mean that information received on a DLCI it would not be able to be forwarded out any of the other DLCIs because they are on the same physical interface 2. You're using "frame map bridge" statements which disables inverse arp. You have to add static "frame map ip" statements for all the layer 3 addresses. This wouldn't explain why it works when the DLCIs are on different layer 3 networks though. Rob Brian @groupstudy.com on 08/21/2001 02:10:42 PM Please respond to Brian Sent by: [EMAIL PROTECTED] To: [EMAIL PROTECTED] cc: Subject: RE: CHALLENGE PROBLEM (was Re: For FR Grus [7:16635]) [7:16711] No one has gotten this problem yet. Remeber, making it so the clients are on differnt layer 3 networks works, but when they are on the same it doesn't. What mechanics are involved in how the packet will be treated different if on the same network vs. different networks. I'll still leave the answer open, someone will get this.

I just checked the 2600 product catalog.

pix & radius auth [7:16705]
I have the following config for auth on the pix 500 series aaa-server RADIUS protocol radius aaa-server RADIUS (inside) host 192.168.1.1 cisco timeout 15 aaa authentication http console RADIUS aaa authentication http outbound 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 RADIUS This should be all I need to put to have it authenticated against the RADIUS server right. When I start my http session via IE it will prompt me but when I put in the username and password, it will not take and will ask again. Sounds like it may be a radius thing but wanted to just make sure. Any input is appreciated. Thanks.

RE: Rapid spanning-tree 802.1w [7:16524]
Unfortunately, none of the suggestions to find 802.1W at Cisco's site worked. Perhaps they just don't support it yet, although a normal Google search did discover that they are working on it. It would make sense since they have been so concerned with improving the spanning tree algorithm for many years, adding things like uplink fast, backbone fast, portfast, and gazillions of other bells and whistles.

No one has gotten this problem yet. Remeber, making it so the clients are on differnt layer 3 networks works, but when they are on the same it doesn't. What mechanics are involved in how the packet will be treated different if on the same network vs. different networks. I'll still leave the answer open, someone will get this.

Putting static routes on the remote routers pointing back to the hub router would work. Assuming the hub router has routes in it's routing table to all the remote routers.

Able to Traceroute but Unable to ping [7:16706]
Hai, I am tryig to analyse a problem that is existing in my network. I have a link with PPP on WAN, Till four days back everything working fine. The problem started four days back, the problem is I am able to traceroute the IPs, but unable to ping to that network. I didn't restricted ICMP on end user. What could be the problem, Does any one had this kind of problem?

Re: Associate and Professional Email Lists [7:16217]
Last week while searching for an answer to a question I had, I ran across this study group. I was very pleased to run across a group that I felt had the same love for network engineering as I. From the sound of some of the emails, Real world " work related " network questions are inappropriate for this email list. I am sorry to hear this since in the last 8 years I have installed countless frame routers, VPN, Voice over iP. In the short time I have been on the list I enjoyed viewing the questions and replying to the ones that I had experience to share. I would like to thank the people who replied to questions. I have been working in the business for about 10 years and realize that I do not have all the answers. Our industry changes too fast. If one asks Cisco for all the answers, all you get is a Cisco solution. My experience with 9 out of 10 consultants is they are great at retaining the information, yet poor at implementation. If anyone can direct me to an email list other than the ones provided by Cisco, who are interested in discussing networking issues I would greatly appreciate it Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=16704&t=16217 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

To me this looks very similar to bridging with DSL. Since you cannot receive the ARP the router must proxy this.

RE: HELP!! The Cisco Code & Windows XP [7:16604]
I wish that Networking 101 was required in schools. Then even the Management by Business Week types would know about the 7 layers and that the operating system, which generally deals with local file management and I/O, should not matter when considering traffic going through routers and switches. In actuality, there may be issues because the TCP/IP stack and other protocols are part of the operating system and they could be buggy, but if they are standard and not buggy, then there shouldn't be an issue. I don't mean to flame the person that asked. It can't hurt to do some research, and there was that one bug with 802.1x security and Catalyst 5000 switches connecting PCs running Windows XP, but that kind of thing shouldn't happen. On the other hand, both Cisco and Microsoft like to take simple concepts (like bridging, etc.) and make them so complicated that bugs are bound to happen. We run an ISP among other things. I wish that our users would take the basic networking class also. This morning someone called and said she had an error message about running out of server space. So I talked to her about not keeping mail on the server. She said, "you mean I can't keep messages in my In Box?" Sigh. Networking 101 would have a short section on client/server architecture too. Sorry for the babbling. Haven't had my latte yet. Priscilla At 12:05 AM 8/21/01, Chuck Larrieu wrote: >I'm sure you've had your fair share of smart remarks by now. So I won't add >my own.

you can correct me here if I am wrong but split horizon is only used in distance vector protocols NO???

Re: A new networking term - thoughts? [7:16668]
I've actually heard that term used before, and I think it *may* have been in one of Howard's books or CertificationZone papers. Maybe not, I'm sure he'll correct me. I do know that I've heard the term "split horizon" in this context before. I agree that we should probably use it more often. A slight modification might be that a BGP speaker will ignore updates that include its own ASN in the path. I don't know if that still qualifies as split horizon since it's the receiver of the route that is disallowing the update, not the sender (as in the case of split horizon in other protocols.)Still, the end result is the same and I think it applies. John >>> "Chuck Larrieu" 8/21/01 9:29:20 AM >>> As a result of an off-list conversation, I came across the following networking term: iBGP split horizon my first reaction was a sarcastic remark about never having come across the term in the RFC's. but then I got to thinking about it, and I now see this as a descriptive and quite useful term. recall that distance vector protocols are subject to the rule of split horizon. they do not advertise a route back out the interface that they received that particular route. one of the gotchas of iBGP is the fact that iBGP routers do not propagate routes learned from one iBGP neighbor to other iBGP neighbors. hence the requirement for iBGP full mesh. so why not call this iBGP split horizon? and define it as follows: an iBGP router will not advertise a route back out the same AS from which it learned the route? does this make sense? worth letting this one join the lexicon of networking terminology?

Re: A new networking term - thoughts? [7:16668]
Interesting, But traditional split-horizon seems to be concerned with the "interface" the routes came in and went out on, whereas with iBGP the routes are not passed even if they come in one interface, but are being sent out another, Its more of a peer level than an interface level.

RE: A new networking term - thoughts? [7:16668]
Chuck, I think there's a difference here. Split Horizon as you say, does not advertise a route back out the interface that it received it on, but the iBGP does not only not propagate a route learned from other iBGP out the receiving interface, but it does not propagate it out any interfaces unless it has been setup as a cluster server. If you would name this, it would probably be something like "iBGP horizon" :-) Just my 0010 cents. Ole ~~~ Ole Drews Jensen Systems Network Manager CCNA, MCSE, MCP+I RWR Enterprises, Inc.

Re: For FR Grus.... [7:16635]

If you dont want to do that use point - to - point subinterfaces and define the DLCI you want to use on the subinterface.
