Hi, I want to change Keepalive timer on the interface like, If s0/0 is down, then it should send the down message only after 5 second. Please help.

I have this problem too.

Hello Rupesh,

the interface will be declared down after missing three consecutive keealives so with default settings it is after 30 seconds

use

keepalive 2

to see if after 6 seconds

Hope to help

Also be sure that the setting of keepalives is the same on both ends of the serial connection. If you set one end to keepalive 2 and leave the other end at the default of 10 you will find that the router with the short keepalives will flap which is caused by the mismatch in the keepalive timer.
