Post #1 of 5 (2645 views)

Hello,

do somebody know the reason for these log entries, that start filling up
for a few days now? Platform is CES 2048CX, with 2x10G module on e2/1,
e2/2:

Regards Jörg

Does 'dm pstat' exist on the CES? It shows a bunch of counters since the
previous run, so ignore the first run.

In our experience when this happens it due to hardware failing which progressively gets worse over time. Normally after opening a case, TAC sends us a complete CES with 10G module and we replace the unit.

Oh ;-/ - thanks for that info, we will concern a replacement of the 10G
module.
