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.

CISCO 2600 Router Flash Image

Hi guys and gals. Not pay attentiong while performing an update, I mistakingly confirmed an erasure of the flash system on my 2600 series router. The dreaded rommon> is returned on reboot. I tried to download the image files from Cisco.com but the password security issues they do not have is preventing me from doing it. If anyone has a copy please help.
Thanks
Wade

No image to send but I can tell you that if you send a blank e-mail to [email protected] from the e-mail address you registered your CCO profile to Cisco will automatically reset your password and e-mail it to you in a few minutes (usually).
Hope this helps.

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´?

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.

Is it possible to purchase replacement Flash Card that came with the Cisco 1811 Router?

I am in desperate need of a replacement Flash card that came included with the Cisco 1811 Router. I purchased the router used and it was working perfectly. I worked my way through all the information provided at cisco.com and had it pretty much configured the way I wanted it. Until the flash card got destroyed. A little embarassed to go into details how it was destroyed, let's just say my Grandson gave it a bath.
It would be great if I could just purchase a replacement somehow with the IOS and SDM on it without purchasing a Cisco Service Agreement, etc. I purchased the router just to further my "Self Education". I have pretty much conquered all the aspects of the Cisco routers, etc. more or less developed for the Home Office user and moved on to bigger and better things. Since I was able to find a Cisco 1811 in good working condition very inexpensively I decided to go for it.
Help from anyone would sure be appreciated.

I am loosing configuration when I power off my Cisco 857 router

I bought new Cisco 857 router from the shop. Router must have been used before as I couln't go in with default username/password cisco/cisco.
Well I followed instruciton and reset password to username and password. Now I finally connected to the Cisco CP express over my IE browser.
I found out that somebody was using a router from the shop so this is why I coun't log to it in the first place. Anyway problem is that when I changed configuration and applied settings it remembers it until I power it off. When I power it on again it remembers all settings from that shop.
It reverts everything back: IP address, previous level 15 account and password - everything like after password reset.
I tried it again and it again lost settings. So I found following instruction:
http://www.cisco.com/en/US/products/hw/routers/ps233/products_tech_note09186a00800a65a5.shtml
I followed it and changed again all settings on the router. My settings are again lost after power off/on. I noticed that when I do first bit it does show
0x2102 not 0x2142 like they think that is password reset mode.
Here is my output from Hyper Terminal:

Please help me as I am stuck and can't go any further....

Hi David White,
Alternatively, after password recovery you can modify the configuration to be what you want, and then issue:
   write memory
to save the configuration. You can then verify that your changes have been saved to the startup config by issuing:
   show startup-config"
The only good thing is that when I switch off a router it erase configuration except my new password which I created after password reset. Everything else is getting vanished (ADSL settings, DHCP, routing ) everything. Even new admin accounts I created.
Well have a question to your above comments. I am new in Cisco so please put as much detail as you can for me to understand. When you say modify configuration do you mean to go to Cisco CP Express graphical interface and then connect router to hyper terminal and execute above commands?
Why router doesn't remember this anyway. There must be some option to change in configuration to make thing permanent when I hit apply changes in Cisco CO Express otherwise it is pointless to heve it.
Phillip
write memory
is
copy running-config startup-config"
Can't this be done via Cisco CP Express or set up router to copy this every time I change this in graphical interface rather going to command line to achnoledge it?
I understand your concern about this router and somebodie's configuration details as you want things to be un-used when you buy them - true. ADSL details belongs to the shop which sold me the router so that is why I don't make a big problem about this. We take most of hardware from this shop and have discount and many good deals with them so I think they have been just testing it and forgot to erease their config. It might be that someone has returned router to the shop and they have repaired it and tested it.
I hope this is a normal behaviour of this router as I have option to replace it in case this is a fault.
Could you please write me step by step guide how can I make changed options stay permanently on router?
thank you
Dragan

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..?

Clearing config on a 2621 router

I would like to completely reset the config on a 2621 router back to factory defaults and re-program from scratch. Is there any easy way to do this? Thanks in advance!

HI, [PLS RATE if HELPS]
Instructions to Reset a Cisco Router Back to Factory Defaults:
Method 1:
This method uses the config-register 0x2102 command in global configuration mode.
Check the configuration register on the router by issuing the show version command. The configuration register setting is displayed in the last line of the show version command output, and should be set to 0x2102. If this is not the case, enter the config-register 0x2102 command once in global configuration mode.
router# configure terminal
router(config)# config-register 0x2102
router(config)# end
If the show version command is issued again, the same line in the command output will have '(will be 0x2102 at next reload)' appended to the current register setting.
Erase the current start-up configuration on the router with the write erase command.
Reload the router with the reload command. When prompted to save the configuration, DO NOT save.
router#reload
System configuration has been modified. Save? [yes/no]: n
Proceed with reload? [confirm]
Once the router reloads, the user will be presented with a 'System Configuration Dialog' as shown below. The router is now reset back to the original factory defaults.
--- System Configuration Dialog ---
Would you like to enter the initial configuration dialog? [yes/no]:
Method 2 :
This method uses the config-register 0x2142 command in global configuration mode.
Enter the config-register 0x2142 command in global configuration mode.
router(config)# config-register 0x2142
This causes the router to ignore the start-up configuration on the next reload. If a show version is issued, the last line in the command output will have '(will be 0x2142 at next reload)' appended to the current configuration register setting.
Reload the router using the reload command in enable mode. It is not necessary to save when prompted to save the system configuration.
router#reload
System configuration has been modified. Save? [yes/no]: n
Proceed with reload? [confirm]
After the router has reloaded, the user will be presented with the 'System Configuration Dialog'. Enter no to the question 'Would you like to enter initial configuration dialog?'
Change the configuration register setting to 0x2102 by entering the config-register 0x2102 command once in global configuration mode.
Issue the write memory command in enable mode to overwrite the existing start-up configuration with the current running configuration.
Reload the router with the reload command in enable mode.
Once the router reloads, the user will be presented again with a 'System configuration Dialog' as shown below. The router is now reset back to the original factory defaults.

Would you like to enter the initial configuration dialog? [yes/no]:

CCO recommends to send in this box to Cisco ! but the new box from my reseller has the same problem / behavior !!!
any idea ?

I did the same thing, TAC support said they've had like 20 people complain about this. He said "there is no reason to update the boot code on a 3005 model. It is only needed on the 3015 and higher models to support RAM chips larger than 256MB." TAC support said DO NOT UPDATE the boot code on the 3005.
I suggested that they make note of this SOMEWHERE in their documentation. He provided me with some hidden low-level commands to erase the boot code, but as he said the 3005 doesn't need v4 of the boot code, and the boot code hasn't been tested for it, it's possible it would just break the concentrator. He then added the only way to 'fix' a damaged boot code is to replace the entire unit. He suggested we not touch it anymore, and leave the boot code running as-shipped.

Cisco 1760 router stays in rommon modus

I am having problems with a cisco 1760 router. When I turn the router on I am getting stuck in rommon mode. When I enter the command: "boot flash:c1700-sv8y7-mz.123-11.T3.bin" , the router will boot the ios image. But when i turn the router off and on, it will return to rommon mode. I have tried the following commands in rommon mode:
rommon 1 > confreg 0x2102
rommon 2 > reset
or
rommon 1 > confreg 0x142
rommon 2 > reset
without results. I get the following errors:

Thanks,

I would recommend posting in the netpro forums about this.
http://www.cisco.com/go/netpro
This site is for the Cisco Small Business Pro routers.
For your problem though, you might try looking at your boot system command in your running config to make sure that it is accurate.

Can I format the CF in a cisco 1800 router and then use it on the ASA 5520?

Can I format Compact Flash in a cisco 1800 router and then use it on the ASA 5520?

You don't have to format the card in the router. You can do that on your PC. Just format the CF-card as FAT32 and plug it into the ASA.
BUT: If you just want to "upgrade" the old card with a different one, then first attach the original card from the ASA to your PC and copy all files (including the hidden ones) to your PC and then copy them back to the new card. That way you also move your licenses to the new card which are stored in hidden files and your private data like keys.

Cisco 3825 router boot ios from usb

HI All
I got a Cisco 3825 Router CF card failure, can I boot IOS from USB?
Physically I found 2 usb ports but nothing I can see in ROMMON mode, may I know how to boot from USB?

Hugo

Hi Hugo,
The only time you can get an ISR G1 (except 870) to boot from USB is when you have upgraded the bootstrap to 12.4(13r)T15.
The command to boot from USB is a hidden command. From ROMmon the command is "boot usbflash0:IOS_filename.bin".

IPV6 on Cisco 3620 Router

Dear Sir,
I have a Cisco 3620 Router with 32 mb Dram and 16 MB flash.
Which IOS will support IPV6 addressing on this Router.
Thanks/Regard
Atul

Hello Atul,
the only way to get the IOS is to download it from CCO, or to get it from a reseller or partner.
Here is the link to the CCO download file:
c3620-is-mz.122-15.T16.bin
http://www.cisco.com/cgi-bin/Software/Iosplanner/Planner-tool/iosresult.cgi?get_crypto=&data_from=&hardware_name=3620&software_name=IP%20PLUS&release_name=12.2.15T16&majorRel=12.2&state=:HW:RL:SW&type=Early%20Deployment
Obviously, your access level needs to be sufficient to download the IOS...
HTH,
GP

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.
http://packetlife.net/blog/2010/oct/11/recovering-no-service-password-recovery-service/
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.

SSLVPN with iPhone Anyconnect and Cisco IOS Router, Certificate Authentication failed

Hello,
i have a problem regarding the authentication with a certificate from the iPhone Anyconnect 2.5 Client to a 1802 Cisco Router.
Cisco 1802 Router:
Cisco IOS Software, C180X Software (C180X-ADVENTERPRISEK9-M), Version 15.1(1)T, RELEASE SOFTWARE (fc1)
First i configured SSLVPN with username and password, in this configuration the Anyconnect Client of my iPhone works.
then i enrolled a certificate from my Windows 2008 R2 CA to the Router with the Attributes: Server Authentication and IPSEC
and i enrolled a certificate for my iPhone with Client Authentication and IPSEC
after a bunch of time ( i realy could not find a really good documentation on how to do this) i got it done, in the webvpn context configuration i made this changes here:
no aaa authentication list default
authentication certificate
ca trustpoint CA
as the "SSL VPN Configuration Guide, Cisco IOS Release 15.1M&T" says: if i want only certificate authentication i had to user the "authentication certificate" command and thats it.
as i look into the debugs it seems to me that the Router accepts the certificate of the iPhone, but then i receive a window on the iphone that wants an additional username and password authentication, and no matter what i enter there's always the same dialog coming back..
any ideas what the problem could be???
here is the configuration:
webvpn gateway WEBVPN_GW_OFFICE2
ip interface Dialer0 port 1444
ssl trustpoint CA
