After upgrading from CM 6.1.1 to CM 6.1.2 I'm having trouble keeping network connectivity to the server. During startup I see it start the ETH0 interface and I can ping the device. I have seen two different times the device stop responding to pings

1) At the normal login screen after bootup

2) At the screen in the screenshot attached the the message.

Any help would be greatly appreciated.

I have tried to login and do a switch version since I sometimes have brief connectivity till "something" stops it.

Check your eth0 connection speed/duplex setting on CUCM and the switchport. They should match.

They were previously set to auto/auto (sp/dup) and worked fine. I just tried moving to 1000/FULL and didn't change anything. I'm also not seeing any errors on the interface as well.

Per image looks like an IBM server.

Which NIC is connected to, how many servers?

Which exact model?

Per image something happens when CLM is invoked.

After all services start|boot up complets connectivity fails or is restored?,

no icmp respose?

Please let us know

NIC 1 is connected.


After I get to the login screen its only active for about a minute or so and then dies(no ICMP response).
