Hello B Bhushan,

it is indeed a strange problem.

I would try the following:

on the switch when setting the port to trunk mode add also

switchport nonegotiate

this would disable DTP on the port. The router does not understand DTP or VTP.but this usually does not lead to problems

also specify the list of permitted vlans with

switchport trunk allowed vlan x-y,z-k

This should avoid the router to be hit by broadcast, multicast or unknown unicast traffic coming from Vlans for which no subinterface is configured. The list should include only the required Vlans corresponding to configured subinterfaces on the router.

Another possible attempt to use a different IOS image on the router

It may be wise to open a TAC service request.

Edit:

I tried to perform a bug search with no results

Hope to help

Giuseppe

Please attach one of the latest crashinfo file here.

Hmmmm ...

Your router is experiencing a crash-boot-loop. It has crashed a few times, created the crashinfo file. The flash has became full (no more space to create a new crashinfo file) and crashed again.

You may need to post the EARLIEST five crashinfo files.

1. Remove all the network modules and HWIC cards;

2. Eject the CF;

3. Using a media reader, delete some of the crashinfo files

4. Insert the CF back to the router;

5. Power up the router.

this router is connected to switch and sw to VSAT to test I shut the VSAT interface and change sw to trunk

router stopped rebooting and I was able to ping to router and sw

I dont think its IOS issue could be VSAT causing router to reboot when its trunk

I don't think you understand.

The router is CRASHING. Something is causing it to crash. It's either an IOS bug, a faulty hardware or configuration error. Anything.

Your last crashinfo file, called "38 224918 Jul 24 2012 08:36:18 crashinfo_20120724-083617-UTC" means the last crash occured on 0836 UTC, 24 July 2012.

Trunk or no-trunk, something is crashing the router.
