Recovery a VPC after an outage.

Hello, I have two Nexus 7000 in a VPC settings. After restarting one of them, VPC services stopped working and servers experienced a traffic cut in their LAN cards. I used the domain command "Reload Restore" in version 5.1, but the problem persists. Any ideas?   Thanks.

Pablo.

Recovery a VPC after an outage.

Hi

From this outputs seems like vpc is fine.

Is the problem still observed on this chassis?

Check "show logging log" for possible reasons of traffic cut. Also I would suggest you to open a TAC case asap - because it would be difficult to troubleshoot iafter some time.
