[j-nsp] EX 4200-24F Not forwarding on 10 G ports after software update

[Jay Hanke]

I haven't tried looking at the LLDP info during one of the outages but the
behavior (interface receives but seems not to send) to match in both cases.

We started having the issue in 9.2 and been on a couple of releases since
then without much luck. We've seen the issue on both 10G and 1G ports.

We're only running into the issue every couple of months on one of the 3
EX4200's we have in service. We're only using a couple of ports on each.

If you find a fix please be sure to share it!

Thanks,

Jay

Jay,

Sounds similar to what I've been dealing with since September 2009 on a pair
of EX-4200 24F's. If it is the same bug you will notice that the SFID will
spike to around 50%, a 'Show lldp neighbor' from the bugged router will see
the upstream router but running the same command on the upstream router will
not see the bugged router. A reboot will fix the issue as well as some
undocumented ATAC commands but the only real solution I found is in the
firmware. Anything newer than 9.3R2.8, from my experience, will bug out
between 1-3 weeks after uptime. 

Juniper has replaced both units to try and fix the issue as they were
thinking it was something in the revision of hardware but both of the
4200-24f's still bug out if the firmware is newer than I mentioned. As of
right now, Juniper RMA'd a spare unit that I'm to run on older firmware and
move all my connections to for when that bug triggers; that way the bugged
unit can be debugged as much as ATAC wants and I don't have to worry about
downtime.

Good luck,

-Harrison

We upgraded a EX 4200-24F from 9.2R3.5 to 9.5S1.2. After the update
everything took and all interfaces came back up with the exception that the
10G interface was not forwarding packets or frames. The 1 G ports all came
up and forwarded fine.

 

We rolled the software back to 9.2R3.5 and the everything worked immediately
after the reload. Has anyone run into anything similar?

 

Thanks,

 

Jay
