WLC 2504 trunk goes down on power outage

Level 9

hi all,

i got a WLC 2504 connected to a WS-C3560X-24P.

the issue is whenever there's a power issue on the remote site, users reports they're unable to use their wifi.

i always need to manually bounce the trunk port on the switch that's connected to WLC even though the port is up/up and wifi is back.

is this a known issue or a bug? need WLC upgrade?

anything i can set on the switch port/trunk so that i don't need to bounce the port in order to restore wifi?

sw01 uptime is 1 hour, 46 minutes

John, 

Upgrade the firmware of the WLC.  It's very, very old.

pre,

will the WLC upgrade solve the 'hanging' problem?

Yes.
