Re: Active Standby Failover

What approach are you using to authenticate 'telnet' or 'ssh' users?  If you are using AAA, be sure that you have the Standby IP address configured on the AAA server for authentication.

Let me know if this helps!

Re: Active Standby Failover

Hello,

Looks like you are seeing quite a bit of errors in stateful replication. Could you post the "show failover" output from the primary as well as "show interface gi 1/3"

Where as Primary i am not able to login via telnet or SSH i need to take the console and then troubleshoot .

Re: Active Standby Failover

Hello,

Can you please try this command on the device that is not letting you use AAA credentials:

test aaa-server authentication

Also, if you have AAA authorization configured, can you disable it and see if that is of any help?

Regards,

NT
