Upgrading the ROMMON Follow these guidelines to upgrade the ROMMON on your switch: 3 Release Notes for Catalyst 4500 Series Software Release 8.x OL-4502-02 System Requirements Caution To avoid actions that might make your system unbootable, read this entire section before starting the upgrade. You can do this procedure entirely over a Telnet connection, but if something fails, you will need to have access to the console serial port. If done improperly, the system can become unbootable. You will then have to return it to Cisco for repair. This section describes an upgrade to ROMMON version 6.4(1). The same procedure applies to other ROMMON versions, but you will have to substitute appropriate version numbers in the upgrade image names. Step 1 Download the promupgrade program from Cisco.com and place it on a TFTP server in a directory that is accessible from the switch to be upgraded. The promupgrade programs are available at the same location on Cisco.com where you download Catalyst 4500 series system images. To upgrade to ROMMON version 6.1(4), download the cat4000-promupgrade.6-1-4.bin file. Step 2 In privileged mode on your switch, use the show version command to verify the ROMMON version loaded on the switch. The ROMMON version number is listed as the System Bootstrap Version. For example, in the following output, the system is running ROMMON version 6.1(2): Console (enable) show version WS-C4003 Software, Version NmpSW:5.5(8) Copyright (c) 1995-2001 by Cisco Systems, Inc.

RE: router CPU utilization on access lists? [7:75002]
So maybe permit and route to null0 in some cases? Then no unreachables are generated because there is a route? Martijn -Oorspronkelijk bericht- Van: Marty Adkins [mailto:[EMAIL PROTECTED] Verzonden: dinsdag 9 september 2003 20:29 Aan: [EMAIL PROTECTED] Onderwerp: Re: router CPU utilization on access lists? [7:75002] Priscilla Oppenheimer wrote: Yes, that's true indeed that access lists don't cause process switching anymore, so wouldn't show up in IP Input. Two exceptions that I failed to mention are logging and the side effect of a deny. By default, a deny causes the generation of an ICMP admin. prohibited unreachable sent to the source of the blcoked packet. Since packets cannot be created in interrupt mode, process context is required. But these are rate limited to two/second by default as self protection. Plus normal traffic shouldn't result in very many denies. But you can inhibit this entirely by configuring no ip unreachables on an interface. If the matching ACE has the log keyword, then process context is required to create the log message and perform normal logging. This too is rate-limited. Thanks for everyone's advice. It sounds like Marty has the right approach. Although access lists aren't process switched, they are generally fast switched unless the router supports some other feature (like silicon switching) or some fancy configuration like CEF or NetFlow? So, the thing to look for is a high utilization caused by interrupts (the number after the slash). I can't safely turn them off and test, so I think I will try to simulate the network and traffic in a lab to test my theory that they are an issue. It's a 2621 router with lots of entries in the access lists that are applied. I think it's time to offload a lot of the policy represented by the lists to a PIX firewall. You can tune the lists by letting it run for a while and then noting the match counts (show access-list). Within each grouping of permit entries, you can reorder the statements to reduce the number of entries that must be compared to reach a match. If the ACL processing is as efficient as possible but is really impacting CPU utilization, then you could enable the turbo ACL feature (access-list compiled). Unfortunately, that's still only available on higher-end platforms, from 3700s on up. Here's a good URL on troubleshooting high CPU util, by the way: http://www.cisco.com/warp/public/63/highcpu.html Thanks Priscilla - Marty **Please support GroupStudy by purchasing from the GroupStudy Store: http://shop.groupstudy.com FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=75233t=75002 -- **Please support GroupStudy by purchasing from the GroupStudy Store: http://shop.groupstudy.com FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html

Ethernet bogs down help has anyone seen this problem [7:75238]
I have a customer that has a small office with a Cisco 56K Frame router. They are running Nat. Now when I plug in the frame side the ethernet side gets constant request for translation then it gets to the point where you can no longer even ping the ethernet side. If I remove the RG45 cable from the frame side. No problem the request stop and I can ping my ethernet side of the router fine with 10ml sec responses all day. The users office is down because he can not get out to the web. I've checked for viruses and everything seems fine. Does anyone have any ideas? This one is driving me crazy.

Re: Difference between Cisco VPN and PIX Firewall [7:75235]
Stnadard answer: it depends. Followed immediately by the standard question: what problem are you trying to solve? The VPN Concentrator does not firewall or filter; it is a specialized tunnel termination device. You may (emphasis on may) need to use it when you are terminating more than about 20 tunnels. That depends on how active the tunnels are and what else your firewall is doing -- how much other work must it do filtering how much other traffic? The Concentrator does offer AES and DH Group 7 (the latter is useful if the other end of the tunnel is a client which can support ECC, but not many can). You need a firewall between you and the Internet. Have a look at the SMR SAFE Blueprint, here: http://www.cisco.com/en/US/netsol/ns110/ns170/ns171/ns128/networking_solutions_white_paper09186a008009c8a0.shtml If you do decide to use a Concentrator, people may differ, but I recommend terminating your tunnels outside the firewall. If you don't, the firewall must either work at the traffic to inspect it properly (which in fact makes it work even harder tore-encrypt, etc. to send it to the Concentrator) or you poke a big hole in the firewall by accepting traffic that looks like it ought to be a part of the tunnel. If your LAN receives public traffic (is there a public-facing server, any kind of mini-DMZ?), then you will want a switch to send tunnel traffic tothe Concentrator and all other traffic to the firewall.

RE: Difference between Cisco VPN and PIX Firewall [7:75235]
Scenario III is probably the most recommended. It is incorrect to say that the VPN Concentrator does not have filtering capabilities. It generally only allows traffic in its public interface necessary for VPN connections, so it is not any more inherently insecure as a PIX. It does not have all of the capabilities of the PIX however, so if you need a true firewall I'd go with a firewall (not necessarily a PIX, I personally think they suck, go with a Check Point).

Communications problem. I don't understand what you are asking. Try using more words. Be verbose. I may be able to understand then...

Beyond that, I don't know what your problem is, so I can't suggest a solution.

Basically you looped two FE ports together. Pick 1 port for your layer 3 routing and the other port to cross connect your layer two tunnels. The vlan ID for the two FE ports must match. The tunnels reference the loopback of the endpoint router. Hope this helps. -Doan Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=75266t=75255
RE: Network Benchmarking/Performance Analysis [7:74808]
For the SAAgents embedded in the IOS, use the IPM (Internetwork Performance Monitor) software. It comes as part of the CiscoWorks package. I don't know if you can buy it as a standalone package. It includes a plug-in to CiscoWorks and a client to install on the pc. It's much easier to configure and view statistics through the GUI.

RE: question on acl [7:75257]
Er, yes you can. Two people have already replied on how. Use a WILDCARD mask of 0.0.0.254. Simple, easy, effective. I'd hate to have to type in 128 permit statements. Probably end up writing a Perl one-liner, but the easier way is to use the proper WILDCARD mask.

RE: NAT and SAP [7:74982]
Different approach: Howmany clients? Static Nat on the router the other way around? Give the server a route pointer to the nat router for the client. You even can choose to give the client a global ip to connect to the server with, like a mail server for example.

RE: Please Help - CIDR - How the bits work [7:75050]
No offense, but this is CCNA material. If you are going for your CCNP, then you should already have your CCNA and know the answer. But anyway...

Steve Reimer, Fred wrote: May be I had advanced access to the new NA material then ;-) In my view, a NA should be able to handle basic RIP, OSPF, EIGRP in a small to medium sized network. That would certainly include CIDR. A NP, IMO, would be for advanced RIP, OSPF, EIGRP, and basic BGP, like for configuring a mid-large sized network for connection to the Internet including minimal BGP. IE, IMO, is for ISP engineers that have to deal with extensive IS-IS, BGP using all options, etc, and large to huge (global) networks.

Use /23 out of your allocation. 200 is less than 256 so use a /24. 50 is greater than 32 and less than 64 so use a /26 for each. The serial links each need a /30.

RE: Please Help - CIDR - How the bits work What I figured out [7:75173]
From what you say, I think you have it, but I'm not sure. Starting from the bottom of a /24 subnet (Class C), you could have a /26 subnet, then two /27 subnets, then four /28 subnets, and finally another /26 subnet. Or you could have two /28 subnets, one /27 subnet, one /26 subnet, followed by a /25 subnet. The combination, and order, does not really matter, as long as no IP addresses within the subnets overlap. For instance, you couldn't have a /26 (64 addresses) followed by a /25 (128 addresses), followed by a /26 (64 addresses). Why? Because there can't be any overlaps. The 64 would start at .0 and go to .63. The 128 would start... Where? It can't start at .64, because that's in the middle of say 192.168.24.0/25 (which is 192.168.24.0-192.168.24.127). It would need to start at .0 or .128. If it started at .128 then it would extend to .255, in which case there wouldn't be room for the last /26 subnet. So, you re-order them and use either a /26, /26, and /25, or /25, /26, and /26. Remember, the whole classful/classless thing is routing protocol specific. It has nothing to do with how hosts view IP addresses, or make routing decisions (meaning whether to send it to a router or if the address is local). The source code for a TCP/IP stack may look something like this: # Assuming addresses/masks are 32-bit numbers, not dotted decimal # string representations of addresses/masks. # $ip_src is the IP address of the outgoing interface on the host # $ip_dst is the IP address of the destination # $ip_mask is the subnet mask on the outgoing interface # $ip_gateway is the IP address of the default gateway # check to see if destination address is in same subnet as our interface if (($ip_src $ip_mask) == ($ip_dst $ip_mask)) { # send directly to destination, possibly arping out first } else { # send to default gateway, $ip_gateway, # possibly arping out first } There would obviously be more logic in there as you may have more than one route and not a single default gateway, but the important point is that it does not matter about the classfulness or classlessness of the subnet mask. The host doesn't give a hoot. As long as the source and the destination both agree whether they are in the same subnet or not everything works fine. If they don't, you may need some ancient hack like proxy ARP, but I don't know anyone in their right mind that would recommend purposefully MIS-configuring a network so that it is required.

Re: Please Help - CIDR - How the bits work [7:75050]
I get the same results as Marko, but this may lay it out so you (and others) can see the development: IP address = 32 bits Network portion = 22 bits Host portion = 10 bits Total addresses for host portion = 2^10 = 1024 Start with 192.168.24.0/22 Focus on the 3rd octet (network_host): 000110_00 400 hosts requires 9 bits (2^8 = 256, 2^9 = 512) and you will have some left in this block divide the /22 into two blocks of 512 addresses each: 0001100_0 (.24/23) and 000_0 (.26/23) use .24/23 for the 400-host network 200 hosts requires 8 bits (2^7 = 128, 2^8 = 256) and there will be some left in this block, too divide the .26/25 into 2 blocks of 256 addresses each: 0000 (.26/24) and 0001 (.27/24) use .26/24 for the 200-host network 50 hosts requires 6 bits (2^5 = 32, 2^6 = 64) and you will again have some leftovers divide the .27/24 into 4 blocks of 64 addresses each now looking at the 4th octet: 00_00 (.0/26), 01_00 (.64/26), 10_00 (.128/26), and 11_00 (.192/26) use the first two for the 50-host networks and the rest is easy My personal rule is to always start with the biggest blocks and work down from there.

Re: Frame Relay Switch [7:75019]
Hi, guys: Why not consider 2523 i/o 2522 ? In the hardware spec, Cisco 2523 is the same as 2522, all the difference is 2523 is Token-Ring based, In eBay, you could find out that R2523 is cheaper than R2522, For the cost issues, I would suggest the 2523. If the cost/price is not the issues, maybe you could consider 4500/4700M+ with NP-4Ts, 4500/4700 has more horsepower than 2522/2523...

RE: Please Help - CIDR - How the bits work [7:75050]
No reason to be sorry! I'm all for vigorous discussion ;-) No BGP in the NA because we are talking about SMALL to medium business. Yes, they should know about how to connect up to the Internet, using a default route, etc. But you are not going to find that many ISPs, if any, that are willing to setup a BGP peer with a store-front business with a 16 address space public network (or even granted they are given a /24 public subnet). If you find any, let me know! That's why I say EGP for NP. A medium to large business certainly may need EGP expertise. And I suppose that's a slight difference in the way people think about the different certification levels. When I say RIP, IGRP, EIGRP, OSPF should be requirements for a NA I mean the candidates should be }experts{ in those protocols. Not just having a passing understanding, have read about it in a book once, or used some study guide to rote-memorize answers to common questions. So, on the one hand I think the standards should be tougher, requiring expert level knowledge for the IGP's, and on the other I don't think a NA needs to know anything about EGP's.

It can have all the VLANs it wants as long as it does not have dual links to the Cisco gear, creating a loop which will not be blocked with Spanning Tree, because it doesn't support PVST+. BTW - what are Hwa Wei switches?

RE: Please Help - CIDR - How the bits work [7:75050]
I've always liked hex myself. A hex mask of FF.FF.F8.00 can be written as F800 and still mean the same thing. You obviously can't do that with 255.255.128.0 (255.255.128.0 != 2,552,551,280). While binary works the same way as hex in this manner, it is much to long for my tastes. Plus, hex is used a lot in programming languages when using values in bitmasks, so I'm more familiar with it. Also, there are only 5 hex numbers that you need to memorize for masks, F 0 8 C and E.

RE: Please Help - CIDR - How the bits work [7:75050]
Oh, it's just getting fun. It's not like we are flaming anyone. We are just expressing our opinions! ;-) I'd agree with you. No BGP for NA's. And as far as who I'd want touching my Internet facing router, it would depend on what type of business it was. If it was a small business, where all they need is a default router that is propagated, I sure as heck would think that an NA would be able to handle that. If it was a large business with say a semi-extensive private WAN with multiple entries into the Internet, I'd definitely prefer at least a NP. If it was a company with dual ISP routing that incorporated BGP, then a NP might be able to handle it, but I would definitely prefer an IE. For ISP's, anyone that would even think of touching the backbone routers I would hope would be IE level, if not certified. It's the experience that counts to me, not necessarily the cert level. Heck, I only have my CCNA so far, but I'd hazard to guess that I have more practical experience than a certain double CCIE that I know.

RE: Basic IP CEF question (again) [7:75161]
Well, the accurate answer is that those are the packets that the router wants to receive (as opposed to switch), but I didn't think that this would be a lot of help. :) You do recognize the common theme across own IP address and broadcast of local net, don't you? Thanks, Zsombor My comments: Hello Zsombor, I can see IP addresses that doesn't belong to the router, for example: Router#sh ip cef | include 10.224.0.51 10.224.0.51/32 receive But the IP address of the router in the subnet is: 10.224.0.49 The subnet is: 10.224.0.48/30 So the IP address 10.224.0.51 is the broadcast address of the router in the network, but not the IP owned by the router. What do you think?? Thx a lot.

It should be assumed that by the time you get to the CCIE level you have much experience in default routing. First, ISP level engineers are going to configure default routes for customers, and, indeed, there often are default routes in POPs, or in smaller ISPs. Second, the combination of static default routes with multiple administrative distances can get quite complex. Third, I am more bothered by the lack of static routes than defaults. Complex static routes, with alternatives, are common for traffic engineering. Blackhole static routes are extensively used.

DLSW+ filter [7:75192]
Hi, I need a little information for a DSLW+ configuration. I have configured two DLSW+ peers (router A and Router B), to connect two LANs (LAN A conneted to router A and LAN B connected to router B). The transport is TCP/IP. I need to configure a filter in router A which will permit pass to WAN only the packets with a particular destination NetBIOS name (a particular host in LAN B) from hosts in LAN A. I understand that I can use a netbios access-list but just to filter particular local hosts by Netbios name, but not by destination name. I tried to use access-expression but I think that it does not work with ethernet interfaces. Could you give me an advice? Thanks in advance Andris Cordoba - Yahoo!

That didn't turn out as well as I thought it would. I couldn't just work up the same level of interest. I have been analyzing the reasons and have come up with the following: 1. I've never worked with switches much, so I don't know too much about them, as opposed to routers. 2. Study materials. I've been wondering, has anyone else faced similar problems in their quest for CCNP. Also, could someone recommend some good materials/resources for switching other than the official Cisco book?

I'm curious if anyone here uses or has used the Orion network monitoring software from Solarwinds. We currently use Network Node Manager but since we use it primarily for fault reporting and statistics gathering I'm toying with the idea of using a product more tailored to our needs. If you've used it before I'm curious about how it performed, how easy was it to understand and configure, was it reliable, etc. It looks like a pretty nifty product from what I can tell from their online demo, but looks can be deceiving.

I agree with Howard that it confuses people and should be taught after the binary representation of addresses (and maybe hex?) Not only does dotted decimal notation confuse people with addresses, but it gets them thinking 8 bits at a time, when programming languages, protocol analyzers, debuggers, etc. think 4 bits at a time.
