Flapping ports on HP 2626 switch

Hello,

 

I have a flapping ports on HP 2626 switches.


Something like that:

I 05/09/05 07:53:34 ports: port 6 is now off-line
I 05/09/05 07:53:37 ports: port 6 is now on-line
I 05/09/05 07:55:29 ports: port 3 is now off-line
I 05/09/05 07:55:31 ports: port 3 is now on-line

 

I explored lot of forums, but couldn't find any reasonable explanation for that issue.

Has anybody resolved it?

I think this is related to bad cable. Have you tried to replace the cables?

 

You could also look if you have any packetloss or errors on these ports.

Re: Flapping ports on HP 2626 switch

Could be anything if you only have those 4 lines. User re-connecting, appliance coming back from sleep-mode etc.

It would be helpful to post the entire show tech all or at least the log files and the SW version as the above does not really qualify as flapping ports.

No, I think It's not a cable because not just a 1 port is flapping and also all patch cables are brand new.

It looks like some ports really going to the sleep mode, but I have never heard about that feature.

 

Also  I've posted output from "show tech all" command bellow:

Re: Flapping ports on HP 2626 switch

Looks normal.
The switch logs switchports as they come up and go down. Switchports come up and go down depending on the device that is patched to it, ie, devices are switched on, rebooted, go to sleep, etc...
