LINK_UPDOWN on many A5120 switches at 3 seconds interval.Bug??

Hello all,

 

I have 25 A5120 switches

 

They run Comware Software, Version 5.20.99, Release 2220P02

 

I see many UP/Down events of the interfaces in the log and they happen almost always at 3 seconds interval, which is strange. This happens to at least 9 switches of the 25

 

I wanted to know if this is a bug and if there is a possibility to debug, since no additional info is in the log.

Re: LINK_UPDOWN on many A5120 switches at 3 seconds interval.Bug??

First of all update the firmware to latest available, currently R2221P12, and see if that help anything.

 

Regarding flapping interfaces this is common for windows hosts during bootup where you can see a flap 2-3 times within seconds. So verify if these clients rebooted at these times?

 

Could also be some kind of sleepmode on the clients?

Re: LINK_UPDOWN on many A5120 switches at 3 seconds interval.Bug??

Can be problems with auto negotiation ...
