I have followed these instructions to setup LACP for my AP-225 series AP's but something is not right. When the AP power up, the the LAG group on the Cisco switch shows the port-channel as up and LACP as on but after about 5 minutes one of the ports goes down and does not come back up. It does this for all my APs. This is what the etherchannel summary looks like after a few minutes for the port channels for the AP-225's:
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
1 Po1(SU) LACP Gi1/0/1(D) Gi1/0/2(P)
On the Cisco (2960x switches) side my ports look like this:
interface gigabit 1/0/1
switchport access vlan 100
switchport mode access
channel-group 1 mode active
interface gigabit 1/0/2
switchport access vlan 100
switchport mode access
channel-group 1 mode active
interface po 1
switchport access vlan 100
switchport mode access
On the local controller I have an LMS IP (local controller vlan) and Backup LMS IP (master controller vlan) set under All Profiles > AP > AP System > "My Profile Name".
Under All Profiles > AP > AP LACP LMS map information I have the LMS IP set and I've set the GRE IP to be one up from that.
The AP's are showing a flag of 2s which means they are set for LACP striping.
What am I missing? Why will both ports not stay up?
