Wireless Access

Hi all,

 

My customer is currently facing issue at 2x 7210 controllers running 6.3.1.1 firmware, the 10G interface running static LAG is encountering input/CRC error thus causing interface link-status keeps flapping (up/down), every time the status boucing, wireless users will get 1 ping drop.

 

In addition, some of the APs will reboot randomly (all campus are using AP 225), i am not sure this is ralated to 10G port issue or not but it happens at different campus.

 

Our core switch is ALU OS 10K and controller are directly connected to core switch using fibre.

Does anyone can help on this issue?

Did you try:

 

- Checking the media

- Using only a single link

Hi Joseph,

 

- Checked the media and changed XFP module at both end;

- disable second link and the single link is still not stable;

Im having the same issue with a 7220 setup in the same configuration. 2 10 gig ports setup with LACP and getting input error on one of the ports.

Hi all,

 

the issue has been solved by changing XFP module....

 

Thanks for the help
