Problem Configuring 2621

Problem Configuring 2621 open original image

I have a somewhat vexing issue, the router is running 12.3(9)



I am configuring this to be a spare for an existing 2621 which is running 12.0(7). I enter all the configuration information and when done do a write to save it and to test it out do a power cycle and when it comes back up it starts a dialog



--- System Configuration Dialog ---



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



And the configuration I entered is gone. So I try the same again, but instead of write, copy running-config startup-config command, power cycle and same thing, the config is gone. Now,



Router# dir all Directory of nvram:/



25 -rw- 2824 startup-config 26 ---- 5 private-config 1 -rw- 0 ifIndex-table


29688 bytes total (25783 bytes free) Directory of system:/



10 drwx 0 its 2 dr-x 0 memory 1 -rw- 608 running-config 9 dr-x 0 vfiles

No space information available Directory of flash:8820 c2600-ik9o3s3-mz.123-9.bin


16252924 bytes total (74040 bytes free)

Now when I look at the files, running-config appears larger even though DIR says it is less than 1/4 the size. What happened to the config I entered? Is there a better wat to rransfer the config from one router to the other rather than a cut-and-paste approach.

Tried same on other router got the same

Tom,

Your router set to ignore config. Check your "config-register". Do "show version", and at the bottom of the screen look for Config Register value. If it's different from 0x2102, then change it to 0x2102:

conf t conf 0x2102 wr mem reboot

Good luck,

Thanks, Mike. I could see al the output of the SHOW VERSION running remotely and talking through a Xyplex terminal server, and must be overrunning some buffers (another problem to solve) anyway I thought it wouldn't to reset the register, but no REBOOT command so issued RELOAD.

Did lose the config I had constructed. How do I copy the config from one router to another?

Tom

Thanks Mike, that appears to have solved my problem

Sorry about that, slipped into Catalyst mode for a second. It should have showed the boot and config-register stuff in show hardware (and show version as well I believe). Glad Mike helped you get this resolved...take care.
