I have tried using end as well as without exit commands. When I test manually with event none it works. I don't have AAA configured on it.

Here is the debug:

*Mar 1 02:12:19.119: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/0, changed state to up

*Mar 1 02:12:19.215: %HA_EM-6-LOG: TEST : DEBUG(cli_lib) : : CTL : cli_open called.

BTW, It works sometimes (maybe 1 out 5) and the other times it just stops at config t.

I don't see any errors here. I put your policy on a 3660 running 12.4(23) with your config, and I get consistent execution every time. One thing I did notice, though, is that your pattern is a bit too lax. It will match %LINEPROTO-5-UPDOWN and %LINK-3-UPDOWN messages. Perhaps you want to do something like:

event syslog pattern "LINEPROTO-5-UPDOWN.*changed state to up"

The fact that you're seeing intermittent success makes me think there is some kind of race condition.
