Cisco 2621

Hello.
I am attempting to reset a Cisco 2621 to factory defaults as i recieved it from a friend so i could study for my CCNA. I could not get the wr erase and reload to work. Any advice?

Sergey,
Try the info at this link.

But somehow you are gonna need to get a comm program that will provide you the ability to invoke the 'break' function. You are pretty much stuck until you find a program that will provide you that function.

Cisco 2621 with 2821

I have a Cisco 2621 with 2FXS and 2FXO for my landlines, can I setup my 2821 to use my 2621 to make outside calls?
Sent from Cisco Technical Support iPhone App

That should work in my opinion. The 2821 is running CCME? But is that worth the effort? Can't you place the VWICs into the 2821 instead in the 2621?

Cisco 2621 Router - Flash Erased

Hi All,
I did something stupid. yes it was me, nobody else to blame,I erased the flash memory on my spare 2621 router. I then rebooted the router and now I'm hung in "romomn" mode.
I have tried the two different recovery modes in order to upload a new IOS onto the router. From Cisco "How to Download a Software Image to a Cisco 2600 through TFTP using the tftpdnld Rommom Command".
I am using Solar Winds for my TFTP server and the replacement image (c2600-i-mz.122-34a.bin) is in the TFTP root. I configure all the proper parameters, then run "set" to make sure they are correct. When I invoke the "tftpdnld" command I keep getting the message that the "IP_ADDRESS" is illegal. Note: This was a spare router and not in production and had no config file on it that I know about. Iam hooked up through a concole cable using Hyperterminal. The IP address of my tftp server (laptop) is 192.168.10.155. I set 192.168.10.240 (spare IP address on my network) as the IP address of the router in romon mode, didn't know what else to put in since the router doesn't have an IP address set.
Next I have tried using xmodem to upload the image and keep getting a "time oiut". Yes, I have reset the speed up to 115,200.
I really need to get this router up and running as soon as possible. This weekend we're changing from BGP to RIP (going from 2 T-1 lines to just 1) and I don't want to change the config on our 3640 until I make sure the new configuration is working on the 2621 first. That way, if things go "south" I cna put the 3640 back into place and be back up and running in minutes.
Any ideas to help me get out of this mess?
Thanks,
Chuck

Are you just connected to the router via a console cable or do you have a ethernet connection between your laptop and the router e0 interface.
The reason I ask is I didn't see it in your post. I might have overlooked it.
Procedures for Recovering Boot and System Images
If your router experiences difficulties and no longer contains a valid Cisco IOS software image in flash memory, you can recover the Cisco IOS image using one of the following ROM monitor commands:
xmodemUse this if the computer attached to your console has a terminal emulator that has xmodem capability.
tftpdnldUse this if you have a TFTP server directly connected to the Ethernet 0 port.

Routing Cisco Cat 2912 VLAN and Cisco 2621

I have a wireless network using 5054 (Proxim). Routing on the units is not very good. I want to route everything using a the Cisco router.
How can I start routing using a Cisco Catalist 2912-XL-E and a Cisco 1750 or 2621?
The attachment has my existing network and a what I want the new network to be.

1750 does not support trunking and hence you can use the 2621 instead. Refer to the following tech tip

Trunking with Cisco 2621 Router

I am unable to configure encapsulation on the sub-interfaces that I have created on this router.I have switches with vlans in them and cannot route.Any ideas?

Hello,
in addition to what Ankur said, do a ´show version´ and check if the name of the .bin file of your image has ´is´ in it. Here is an example of an IOS IP Plus image name:
c2600-is-mz.122-31.bin
If you are not sure which version you are running, can you post the output of ´show version´?

Help Setting Up A Cisco Lab For IOS Upgrade?

Hi.
I've collected quite a few routers and switches over the past few months that have what seems to be corrupted or no IOS. I have a small lab set up to test parts, and I was wondering how I can network them in such a way where I have an active functional network (for testing purposes, not for actual internet use), that I can connect routers or switches to and upgrade or change the IOS version.
I have all the hardware and cabling needed, and I have the Cisco IOS software for the routers I need, I've just never upgraded or changed an IOS on a router or switch before.
I have:
a Cisco 7505 with an RSP4+, 256MB RAM, 16MB Flash, and it's full of the modules that hold the PA cards (I forget what it's called, but I just use it to throw PA cards in to test 8 at a time).
A Cisco 3450 (I believe, 3400 series anyhow) that I believe is 64/16, that again I use for testing.
Two Cisco 2621 64/16, for testing WIC's, VWIC's and NM's.
Two Cisco 2950 series switches, one I'd like to use to actually connect to my LAN already implimented seperatly, and one to connect to this mini lab LAN.
So again, I'm wondering how I can set these up on a small LAN just for testing purposes and so I can just connect a device and upgrade it's IOS. I also need information about the TFTP server and all of that as I haven't been able to find out much info on it.
Thanks in advance for any help :).

Hi
First of all make sure that the flash is enough for IOS you are loading.Here is guide for loading IOS.
(1)Download and install tftp server from www.solarwinds.net
(2)Give IP on ethernet port of router
(3)Give IP on computer which should be in same subnet that of router
(4)Follow the following steps:
Router#copy tftp: flash:
Address or name of remote host []? 192.168.1.67
Source filename []? c1700-k9o3sy7-mz.122-15.T9.bin
Destination filename [c1700-k9o3sy7-mz.122-15.T9.bin]?
Accessing tftp://192.168.1.67/c1700-k9o3sy7-mz.122-15.T9.bin...
Erase flash: before copying? [confirm]
Erasing the flash filesystem will remove all files! Continue? [confirm]
Erasing device... eeeeeeeeeeeeeeeeeeeeeeeeeeeeeee ...erased
Erase of flash: complete
Loading c1700-k9o3sy7-mz.122-15.T9.bin from 192.168.1.67 (via FastEthernet0): !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

RSA SecurID and Cisco ACS integration for user(s) with enable mode

I thought I had this problem figured out but I guess not.
I have a Cisco 2621 router with IOS 12.2(15)T17. Behind the
router is a Gentoo linux, RSA SecurID 6.1 and Cisco ACS 3.2.
I use tacacs+ authentication for logging into the Cisco router
such as telnet and ssh. In the ACS I use "external user databases"
for authentication which proxy the request from the ACS over
to the RSA SecurID Server. I installed RSA Agents with
sdconf.rec file on the Cisco ACS server. I renamed "user group 1"
to be "RSA_SecurID" group. In the "External user databases" and
"database configurations" I assign SecurID to this "RSA_SecurID"
group.
Everything is working fine. In the "User Setup" I can see dynamic
user test1, test2,...testn listed in there as "dynamic users". In
other words, I can telnet into the router with my two-factor
SecurID.
The problem is that if test1 wants to go into "enable" mode with
SecurID login, I have to go into "test1" user setting and select
"TACACS+Enable Password" and choose "Use external database password".
After that, test1 can go into enable mode with his/her SecurID
credential.
Well, this works fine if I have a few users. The problem is that
I have about 100 users that I need to do this. The solution is
clearly not scalable. Is there a setting from group level that
I can do this?
Any ACS "experts" want to help me out here? Thanks.

That is not what I want. I want user "test1" to be able to do this:
C
Username: test1
Enter PASSCODE:
C2960>en
Enter PASSCODE:
C2960#
In other words, test1 user has to type in his/her RSA token password to get
into exec mode. After that, he/she has to use the RSA token password to
get into enable mode. Each user can get into "enable" mode with his/her
RSA token mode.
The way you descripbed, it seemed like anyone in this group can go directly
into enable mode without password. This is not what I have in mind.
Any other ideas? Thanks.

Gatekeeper / Zone Local command in Cisco

This works correctly, but if I add .

Did it give you a syntax error, or did it tell you the zone already existed?
To change the port for that local zone, you'll need to first remove it:
no zone local cnibhco111 .*****.*e 192.168.230.129 1719
then re-add it with the new port:
zone local cnibhco111 .****.*e 192.168.230.129 1723
Take care that you have a copy of all zone prefixes or aliases using this zone. When you remove the zone for the port change, you'll lose any additional gatekeeper configuration that relies on that zone.
Let me know if this helps by rating the post.

Can't set encapsulation on Sub-Interaces - 2621 Router

I am studying for my CCNA, playing around with a few of the dirfferent concepts with my hardware. I am trying to setup a router on a stick configuration using a 2600 router and a 2900 catalyst switch.
I have the FastEthernet 0/1 port plugged into Fa0/1 on the switch. The switch has three vlans setup with a client on each vlan
I have set the port on the switch as follows:
Switch(config-if)#switchport mode Trunk
Switch(config-if)#switchport trunk native vlan 1
Switch(config-if)#switchport trunk encapsulation isl
When I try to set the router, I get this:
rt01(config)#int fa0/1
rt01(config-if)#no ip add
rt01(config-if)#exit
rt01(config)#int fa0/1.1
rt01(config-subif)#encapsulation isl
^
% Invalid input detected at '^' marker.
I cannot set the encapsulation on the sub interface, ISL or dot1q - it doesn't recognize the "encapsulation command" command at all.
My show version is below. I can't confirm one way or another if this image supports IP Plus (which I've been told may be the problem), but based on the message I get when trying to set the IP address on the subif I would think it does..?

Hi
c2600-i-mz.123-6.bin is the IP (not IP Plus) version of software. This doesn't support dot1q or ISL trunks.
The IP Plus would be required for this feature (image name for the plus equivalent of your image would be c2600-is-mz.12.3-6.bin)

Transmit error in 2621 router

Dear All,
I got the following errors from my cisco 2621 router - the network connection between our ISP and our router suddenly unstable and have packet lost. But after router reload, the problem will be resolved.
This error message does not show up from time to time but today it happen again. Last time this problem happened, i had checked with ISP engineer to make sure "Duplex & Speed" are the same between our router and their network switch.
From Cisco website, the problem explanation is "Possible causes are usually incorrect cabling or a non-compliant number of hubs in the network. Bad network interface cards (NICs) can also cause late collisions". I personally don't think this is the problem, so any other reason ? E.g. IOS version not stable ?

Hello Alex,
just to make sure: when you say that you have checked speed and duplex settings on both sides, does that mean that both sides are set to fixed full duplex and speed settings (no autonegotiate) ?
As for the UNDERFLO error message, this is what CCO says:
Error Message
%AMDP2_FE-3-UNDERFLO: AMDP2/FE([dec]/[dec]), Transmit underflow
Explanation While transmitting a frame, the controller chip's local buffer received insufficient data because data could not be transferred to the chip fast enough to keep pace with its output rate. Normally, such a problem is temporary, depending on transient peak loads within the system.
Recommended Action The system should recover. No action is required.

If so which version do I need? And where can I get it?

Dan,
There is nothing wrong in the version of code that you are running but the feature set "IP" does not support 802.1Q Trunking.
You need a minimum of "IP Plus" for 802.1Q Support.
Before you load the 12.2(37) "IP Plus" Feature set on the 2621 make sure that you have enough Flash and Memory.
The minimum Flash required for 12.2(37) "IP Plus" feature set is 16 MB and 48 MB for Memory.
Based on your show version output, you have only 8 MB of Flash and 32 MB of Memory. So, you need to upgrade the Flash and Memory before you do the upgrade.
Hope it helps.

Arul

Raplacing 1 2621 with a 3825 but having routing issues

Hi,
I have two main orivate subnets currently running off one FastEther Iteface on a Cisco 2621 router, with 10.1.1.251 and 10.1.4.251 being primary and secondary gateway respectively.
Now, I have got a Cisco router 3825 with two GigiEther0/0 and 0/1 Interfaces and want to have these two subnets to be off these two interfaces. I don't know if my two subnets willbe able to talk to each other?

ip route 63.66.134.106 255.255.255.255 10.222.222.2
Above was the ACL I use between these subnets. pls ignore the Ip route statement for 10.1.2.0 which is meant to be isolated.
Pls advise,
Masood

access-list 102 permit ip any any

When you migrate from single interface w/ two IP to two interface w/ two IP, this is fine to have this change. But you have to know how the new interface connect to the network ?
Could you please advise how the router connects to the network and where will the 10.1.4.0 connect to ?
The main issue is you have to define the return path of those traffic. Could you please provide a network diagram w/ IP address then we can advise the configuration.
For the ACL, I suggest to separate it to two sets, one for 10.1.1.0 interface and one for 10.1.4.0 interface. It is easier for modification in future. I don't find any problem when you setup those ACL. But you can remove all permit statement and keep the last one "permit ip any any" is enough. The reason is you only need to block those unwanted traffic and you do not require to apply the permit list if you have the "permit ip any any" at last. The "permit ip any any" already permit all traffic.
If you want the 10.1.1.0 & 10.1.4.0 won't talk to each other. You can remove any related static route in remote router. e.g. at 10.1.4.0 connected remote router, remove the static route for 10.1.1.0, but keep 10.1.5.0 if there is a need. So if the traffic go to 10.1.1.0, it will be dropped due to no route for these specific subnet.
Hope this helps.

Bug in ip routing in WRT54GL?

Hi everyone! During Christmas I had some problems with my WRT54GL. I'm connecting to the Internet with a Speedtouch 510 with PPPoE and dynamic ip. The Speedtouch takes care of the PPPoE login and it's set to "PPPoE in bridged mode" which means that the public ip address is passed to my computer/router or whatever is put on the "LAN" side of the modem. When I was away for Christmas I noticed that I couldn't reach my home computer anymore. When I got back the ip for my connection had changed. I usually get a 83.177.x.y address with the gateway 83.177.8.1, but this time I got the ip 90.130.6.30. Neither my computer or the WRT54GL could ping or reach anything outside my WAN ip. Until then I had been using the tomato firmware, I tried installing the original Linksys firmware, but I got the same result. Connecting the Speedtouch directly to my computer worked fine, which to me kind of proves that something is wrong with the WRT54GL. Any ideas on how to troubleshoot this? My solution was this; I think the problem occurs because of a bug in the WRT54GL firmware. The following configuration (recieved through dhcp) works fine: IP Address 83.177.13.213 Subnet Mask 255.0.0.0 Gateway 83.177.8.1 the following works when connected directly to the computer, but not when using WRT54GL: IP Address 90.130.6.30 Subnet Mask 255.0.0.0 Gateway 83.177.8.1 The solution was to power off the modem long enough for the dhcp lease to expire, power it on and hope to get a 83.x.y.z ip address (which I got and then everything worked as usual). I'm guessing the WRT54GL cannot handle either the subnetmask of 255.0.0.0 on the WAN interface and/or maybe in combination with the gateway on a address which differs from the wan ip. Thankful for any comments on this. Cheers, Tobias

Thank you Rich! Yes, that link between NetFlow and routing-not-bridging is beginning to sink in for me.
My reason for bridging is that I do not need VPN or NAT, I just need the subnet (ip) traffic to flow from gi0/1 to gi0/0 and back. I have been reading and re-reading this article, http://www.netcraftsmen.net/resources/archived-articles/428-integrated-routing-and-bridging.html, and it seems that "concurrent" or "integrated" routing and bridging may be the way to go.
I am concerned that, to the extent that the ip traffic is bridged (not routed), it will be invisible to NetFlow, for exactly the reason that you describe. So even if I set up a CRB or IRB, I might not get useful NetFlow data.
Or maybe there is a way to configure ip routing so that there are hardly any decisions made, rather the subnet goes straight through in both directions. I fear that is such a simple case that no one makes examples for it. I have been assigned half of a class C subnet, e.g. 209.201.225.1 through .127. I am not terribly short on ipv4 numbers so I can use up a number for the gi0/1 and/or gi0/0 and/or BVI interface(s).
For ~14 years a Cisco 2621 router has been used "here" purely for the purpose of traffic shaping. I recently upgraded to the Cisco 1941 and am keen to take advantage of traffic peak shaping and NetFlow v5 or v9. I took the config from the 2621 and used it as the basis for my config for the 1941.
I am (obviously) very new to all this and self-taught. My expert is currently ridiculously overbooked so I am trying to figure it out. In other words, I will not feel offended if you need to state the "obvious" to steer me in a useful direction.

Hi Dhaval
Is it a VPN connectivity given by your ISP or a internet connectivity ?
If its a internet connectivity the best tool would be doing simultaneous downloads by directly connecting only one PC or laptop on the ethernet port of the router.
you can try downloading different files of different file sizes from different sites which may help you out to the check out the the throughput capacity of you connection.
Also you can verify the loading conditions on the interface which can tell you the input and output loads coming in and out of the line.
