How to use snmpset to change the tacacs server ip for 3925?

[frank]

Can anyone help to show me how to use snmpset to change the tacacs server IP address for a 3925 router?

I got the syntax as "snmpset -v 2c -c "string" "3925-ip" 1.3.6.1.4.1.9.5.1.16.9.1.1" but was getting "No Such Object available on this agent at this OID".

Is the 9.5.1.16.9.1.1 correct OID for 3925 tacacs server address?

The OID you are using is a Read Only string which will only share the IP address of Tacacs Server.

I don't think due to security restrictions, we have any MIB which can set the Tacacs server IP on a device.

Though, the workaround to do this can be :

1. Use snmp to retrive device confguring using snmp on a tftp server.

2. Change config of Tacacs server and re-deploy the configuration on device.

For details on this, you can check :

If anyone has other information on how to change Tacacs server IP using snmp on this forum they can share.

Hi Frank ,

I agree with my friend Vinod. this object is READ ONLY.

tacacsServerAddr       1.3.6.1.4.1.9.5.1.16.9.1.1     IpAddress        read-only

I also get the below error when I tried the same:

Error in packet.

Reason: noCreation (That table does not support row creation or that object can

not ever be created)

Failed object: SNMPv2-SMI::enterprises.9.5.1.16.9.1.1.0

Thanks-
Afroz
