Switching

Hi,

I installed a pair of EX4300 a few weeks ago. Very simple setup, and using virtual chassis.

Today I had to make a few changes to the configuration, but commit failed:

root@tpsw01# commit
fpc0:
configuration check succeeds
fpc1:
error: Check-out failed for Chassis control process (/usr/sbin/chassisd) without details
error: configuration check-out failed
fpc0:
error: remote commit-configuration failed on fpc1
error: commit failed

The log doesn't show much interesting:

tpsw01 mgd[10495]: UI_COMMIT: User 'root' requested 'commit' operation (comment: none)
tpsw01 mgd[10495]: UI_CHILD_EXITED: Child exited: PID 11979, status 7, command '/usr/sbin/mustd'

Both switches are running the same version of Junos, 17.3R3-S4.2:

Any ideas?

I tried to do a "commit full" but with the same error message.

hi there,

can you show us the output of:

#commit | display detail

it seems to be FPC1 thats not committing this might give us a better lead

OK, here's the output:

Any ideas?

Are you using DAC cables to make the VC connections between FPC0 and FPC1? Can you paste the output of "show chassis hardware"

Yes, I'm using DAC cables.

This is the requested output:

And yes, now I see the problem. The DAC-cables are reported as "UNKNOWN". I'll try changing them.

Try changing the cables, I have seen this issue and it was a problem with the cable. After replacing the cable I was able to commit. 

I hope that helps in your case as well.
