Hi ... We have a problem with WLC 2125-K9 V04 sw 5.2.157.0 connected to a Catalyst 3560.VLAN 900, which is the management VLAN, fails to work on some VLANS on the switch.On VLAN 904 and 905 we have two servers, that can ping the WLC on its management address, But VLAN 901 an 902 cannot ping the management interface of the WLC.The ports on the 3560 is identically configured. However, it was functioning well until we configured the WLC for another routed VLAN. But everything is back to where it was functioning, but no ping to VLAN 901 and 902. I know you need more info to solve the problem, buts it is a beginning .....

Thanks for answering ...
First of all. how to make attachments here. I have listed the tech and run commands, and want to send them to you.
By the way, we can ping from the wlc router to the PC client on another vlan, but not the other way. On some vlans its ok.
I doubt that this is a configuration error, since it all worked before. But its ok to check it. Thanks for answering ... First of all. how to make attachments here.

Hi .....
When upgradging the software in the WLC, everything is ok.
There was a bug in old software. (5.2.157.0)
