Hello
I have recently updated our 3750g-24PS switches they are now running
12.2(58)SE2 with C3750-IPSERVICESK9-M
The switches are working BUT
the leds over each of the ports are flashing much more that before. They are not a steady flash, but seems to start and stop with some random cycle.
Thery do this even when swictjing between modes using the front panel button
before i contact TAC. has anyone else seen this?
should i d/l back to the old version or some other new version
any advise would be usefull

Hi Walter,
Are you noticing any issues with respect to the switch's operation (high cpu or forwarding latency etc) ?

This usually occur if there is some loop or high cpu..Following outputs will help-
sh proc cpu sorted (when the LEDs flash)
sh proc cpu history

Is your switch the ones that come with 16mb of flash?

Hello:
Thank you all for the responses so far
I do not notice any switch operation issues
The CPU traces below seem to show a busy switch over the long term ,
but short term shows negligble work (;
Devices are not showing any drops or delays. though the front panel lighhts are worrying me as the previous IOS c3750-advipservicesk9-tar.122-46.SE was OK
here are a few details from the switch
