SNMP <set> in catalyst C3548XL

[antoni.anton]

Hi,

I've make a BIG mistake configuring a 3548-XL. I've configured all "authentication, authorization & accounting" option to validate a Telnet users from a TACACS server, but,.... the big mistake is that I've not write de sentence "tacacs-server host A.B.C.D" and I've saved running config to flash.

Now, when I telnet a switch never validates and the switch is in remote office.

My question is:

Is possible to make a SNMP-set to change this OID (tacacsServer) with an IP address? What is excatly the MIB & OID I need to write it?

I prefer to do an SNMP-set comand instead of "Standard console password recovery procedure"

Example, I want to set the server tacacs variable with a sentence like this

"snmp -o set -c private -ip 192.161.25.22 -b | enterprises...cisco.....tacacsServerAddress=192.161.25.88"

Thanks

I'm not aware of a MIB that will allow you to remotely add the tacacs command. Here is an smnp link that might be helpful...

If that does not help, your other option would be to have someone local to the router console in to make the changes.

I'm using the following procedure to change configuration on switches with IOS like this : c3500XL-c3h2s-mz-120.5-XW

First make a small configuration file on your TFTP server and name it ex. tacacs-confg. The file should only contain the lines :

tacacs-server host A.B.C.D

end

Then depending on your switch, do a snmp set to one of the following OID's :

...enterprices.cisco.local.lsystem.netConfigSet.X.X.X.X octet_string tacacs-confg

or

...enterprices.cisco.local.lsystem.hostConfigSet.X.X.X.X octet_string tacacs-confg

where X.X.X.X are the IPaddress of your TFTP-server

This should load the partial configuration into your running config.
