Switching

Hi all,

I have virtual-chassis with next configuarion:

***@SW5> show configuration virtual-chassis
preprovisioned;
no-split-detection;
member 0 {
role line-card;
serial-number ***;
}
member 1 {
role line-card;
serial-number ***;
}
member 2 {
role routing-engine;
serial-number ***;
}
member 4 {
role line-card;
serial-number ***;
}
member 3 {
role line-card;
serial-number ***;
}
member 6 {
role routing-engine;
serial-number ***;
}

I detected that all ports on FPC4 went down, but FPC4 uptime didn't change. I found next info in logs:

Jul 20 04:48:01.154  SW5.M9P.MSK fpc4 PFEMAN: Master socket closed
Jul 20 04:48:02.163  SW5.M9P.MSK fpc4 Routing engine PFEMAN reconnection succeeded after 1 tries
etc...

I attached all logs.

I suppose that there was some soft/hard crach with RE on FPC4.

Have anybody same issue?

Hello,

Which version is installed?

Do you see any crc on vc/vcp links? >> show virtual-chassis vc-port statistics extensive | grep crc

Any core file been generated? >> show system core-dumps all-members 

Any specific error from logs on FPC4 >> request session member 4 >>> show log messages (around time of the issue)

If nothing found I would suggest open JTAC case.

Hello,

Thanks for your support. It's really helpfull.

In logs for FPC4 I found next message:

Jul 20 04:47:55.749  SW5.M9P.MSK /kernel: Buffer management parity error detected in mpfe0, value 0x10001, re-init the PFE

There is description about it here:

It was memory crach on PFE. Thank you.
