Switching

Hi everyone,

I have a pair of EX4300 in VC mode that is running version 18.1R3-S6.1

Member 0 is the master.

Before the issue occurred, there were a lot of logs below:

10:45:30  pfex: CMLC: Error writing 'CM FPC status' msg to Master
10:45:30  fpc0 CMLC: Error writing 'CM FPC status' msg to Master

10:45:41  pfex: CMLC: Error writing 'CM FPC status' msg to Master
10:45:41  fpc0 CMLC: Error writing 'CM FPC status' msg to Master

After that, the routing engines were restarted with reason: Last reboot reason             0x1:power cycle/failure

The interfaces were down.

Can somebody help me with this?

Thank you.
