Issue Description

UltraVR Interconnexion error while adding FC Components,saying connect the FC we want to add abnormal

Alarm Information

communication is abnormal

Handling Process

We use VR and FC to ping each other and discover that it can pass, and the configuration on VR is no problem.

We collected the VR debug log and found that VR failed to get the FC version. We still suspect that it is a network problem.

we test port,found it is also fine,so we think maybe a MTU issue

Root Cause

the MTU allowed on customer switch is 1372  and the one allowed on the VM's is 1500 we fixed it after reducing the MTU value to 1300 the problem solved.


reducing the MTU value to 1300 in switch


When the component fails to be added, the network can ping each other. Please check the MTU value.
