We have a Strange issue , our Capwap tunnel between central WLC and Anchor WLC gets randomly down , and we run eping and mping between the Controllers the Tunnel gets back up. This issue is happening randomly but recently it happens frequently. And at each time we have to run the eping and mping to resolve this issue
Central WLC Model and version : AIR-CT3504-K9 , 126.96.36.199
Anchor WLC Model and version : AIR-CT2504-K9 , 188.8.131.52
we have a FW between the 2 WLCs
please anyone has a idea about this behavior his explanation and solution for this issue are very welcome.
Many thanks in advance.
1. Also its not must but try with same software version on both WLCs.
2. Remove the mobility IP/Mac completelz from both WLCs and add it again.
These are just workarounds..
Thank you to all of your advices guys, we doublechecked the log on the FW and the WLCs during the issue and they did not show any thing as abnormal.
Any way we will get back with more details if this issue happens again
for upgrading the software that the WLC would have the same Software I have to say that we have the same scenario in another site and they are working properly with different software.
