I have the folowing problem:
An AP 3825i (V9.21.02) ist connected witch a LACP Port Channel on a Cisco 3560 Switch
After Switch reboot the AP is not coming up, because the POE recognition is faulty. On the Switch I see no POE Device.
When I disable one of the swichport, the AP becomes a POE Power immediately. When the AP is up and I enabe the second Port the LACP Channel goes up an everything is o.k.
It is always no problem when I disable the POE on one Port of the Channel.
Is anyone aware of the problem ?
here the config of the switch :
interface FastEthernet0/2

channel-group 20 mode active
spanning-tree portfast
interface FastEthernet0/4
switchport mode access

After Switch reboot:
