hello

i have a stack of 3500's where the rear-ports simply stop working.

the devices work in stacking mode for up to 12hrs then when they stop, the front LED's don't show them stacked and when I issue show rear-ports the command is not even valid...

anyone ever see anything like that before?

Nope,

doesn't ring a bell, and have quite a few running..

Sounds like a bug, which code are you running?

No.  Never heard of that before.  It sounds like either a code bug or a hardware fault.  If you are not running the latest version, try upgrading and see if it helps.  Otherwise that sounds like something you would have to place a call to Avaya about with help either RMA'ing the gear or diagnosing the fault.

thanks everyone for getting back to me so quickly.

Ethernet Routing Switch 3526T-PWR+    HW:15       FW:1.0.0.15  SW:v5.2.2.003 BN:03 (c) Avaya Networks

this is interesting in the sense that i've never had hardware do this before, pretty bizarre even for avaya!

i will check out the release notes of the next version and call in, either way, always good to post to the forum so people can search for the issue!

Looks like you're running the latest code.

When the issue occurs, do you notice other strange things with the switch? Does the stack write something to the log about the issue? Have you checked the "last exceptions" log?

Also, if you can reproduce the issue, you might want to connect a laptop on the console port and record all output to see if the units echo anything to the console at the moment of failure..


Greetz,

Johan

when the issue first appeared i factory defaulted both units, re-did the firmware then restacked the units - they worked for 12 hours and then i got a call shortly after.

when i arrived the port lights for 27/28 rear were off so i quickly factory reset and just went from switch to switch no stacking...i plan on replacing the switches and bringing them back to the office...i do have the stacking cables in a stack at my desk but there have been no failures...

when i do a show system last-exception the output i get is likely not from when the issue failed but I'm not 100% sure...

interestingly enough when i try to do show rear-ports mode on any stack the command disappears perhaps it does once the stack is created because the rear ports are in use - when i do a show stack-info the stack appears to be fine.
