[c-nsp] Reset an interface automatically when it goes down?

[Wolfgang Roth]

Hello list,

we use a Cisco 3640 with NM-2V and VIC-2BRI-NT/T modules as VoIP/PTSN 
gateway. The device is running a 12.4(12) enterprise image.

Sometimes unpredictable one of the BRI interfaces goes down (with ISDN 
state 'AWAITING_ESTABLISHMENT'). Until now we weren't able to find a reason 
for this behaviour. Resetting the interface with the 'clear interface' 
command immediately brings the interface up again.

What we want to do now is to automatically execute a 'clear interface 
BRIX/Y' command when this happens. Is that possible and what would be the 
best way to achieve this (cron job, TCL script, ...)?

Any help is welcome!

Thank you,


Wolfgang
