[c-nsp] cisco-nsp Digest, Vol 47, Issue 53

[Rick Williams]

Hi jr,

You might try something like the following:

event manager applet testit1
event syslog pattern "%SYS-5-CONFIG_I: Configured from console by  
console"
action 1 cli command "en"
action 2 cli command "conf t"
action 3 cli command "event manager applet testit2"
action 3.1 cli command "event timer watchdog name doIn30secs time 30"
action 3.2 cli command "action 1 syslog msg \"testit2 ran\""
action 3.3 cli command "action 2 cli command \"en\""
action 3.4 cli command "action 3 cli command \"conf t\""
action 3.5 cli command "action 4 cli command \"no event manager  
applet testit2\""
action 3.6 cli command "action 5 cli command \"end\""
action 4 cli command "end"
action 5 syslog msg "testit2 set by testit1"
!

snow#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
snow(config)#^Z
snow#
Oct 16 13:37:18.491: %SYS-5-CONFIG_I: Configured from console by console
Oct 16 13:37:19.843: %SYS-5-CONFIG_I: Configured from console by  onvty0
Oct 16 13:37:19.000: %HA_EM-6-LOG: testit1: testit2 set by testit1
snow#
snow#
snow#
Oct 16 13:37:49.000: %HA_EM-6-LOG: testit2: testit2 ran
Oct 16 13:37:50.010: %SYS-5-CONFIG_I: Configured from console by  onvty0

Basically, register another applet with a watchdog event based on the  
syslog. When the second applet runs, it unregisters itself.

Alternatively, you can use a Tcl-based policy.
