Hi all,
A have a stack Enterasys B5 with 4 equipments in the IDF. In some cases, some users told me that are out of the network and suddenly are on line again.

I made a review of the switches, and found this in the log:

So, my question is:

- is there a problem with the switch? I mean: IOS, firmware, cable o the appliance? do I have to upgrade the firmware? the info about this is this:

Chassis Serial Number: xxxxxxxx
Chassis Firmware Revision: 06.71.02.0008

IDF_P4(rw)->

UNIT 2 HARDWARE INFORMATION

POE Board Version: 0.0
FirmWare Version: 06.71.02.0008

I hope this info be usefull to help me to find the solution.
Thank you!!
P.D. Sorry for my bad english.

Good Day to you Manuel, It could be a number of things but i particular I would run the show switch stack-ports and see if there are any errors. Could be a bad connections(maybe try an reseat each connector on the back of the stack Maybe this would be a good start by checking those cables by disconnecting and then connect them one at a time. if you do show switch do they report the same firmware on all switches? You might want to call into the GTAC so we can assist. I wanted to start you off with something to check. Ifyou run the command dir Dmp and see dmp files then I would contat the GTAC and WE can assist you. You can feel free to use my name Jason and I can try to assist. Here are some files to collect before calling into the GTAC so you can have everything prepared to moving forward to addressing your issue look for this first: dir Dmp (This shows all of the files that are hidden with a doing a dir) and then type: . -Copy Dmp tftp://x.y.z.w/name.z  will bundle all of the files from all of the units into one file. -Show Support -To collect the Current.log copy logs/current.log tftp://192.168.0.1/current.log
