Cisco 4506 getting restarted

I have Cisco 4506 with Sup V. It is has been joined with one of the VTP domain, but the switch is in Client mode. There are around 10 switches which are connecteing to that switch with trunk ports.

The switches which are connecting, some are in Transparent Mode and some in Client mode.

This switch is a root switch. The problem what I am facing with this switch is it has got hanged twice and restarted once. There is no config changes which are been made since it has been installed.

Can anybody please help me out.


Re: Cisco 4506 getting restarted

When it restarted, was there any useful information in the show vers about why it restarted?

You mention the VTP domain. Is there something that leads you to believe the problem is related to the VTP domain?

Re: Cisco 4506 getting restarted

No I could not see anything which could tell me the reason.

I have mentioned VTP domain because I had a doubt that this might also create a problem.

What do you think could be reasons which make this 4506 switch to restart

Re: Cisco 4506 getting restarted

have you physically changed the switch from one place to another, because even an voltage problem could also lead in such situationz, apart from this, you also try upgrading the OS in the switch. becuase changing the VTP domain it is not at all possible in making a switch getting restarted or hang.

rate this post if this information is helpful.
