Hello, I have an issue connecting all four SFP's on my 4404's (I have two). Currently I only have two of the SFPs connected on each controller and each controller supporting 50 AP's. When I connect the third SFP port (dot1q trunk and switchport mode trunk on the switch) with STP set to Fast- It goes into Blocking. All Interfaces are on the same vlan. Currently I have two AP-Manager Interfaces with 1 set to physical port 1 and 2 set to physical port 2. All have Enable Dynamic AP Management checked. When connecting Port 3 I created AP-Manager-3 Interface with the physical port set to 3 and Enable Dynamic AP Management Checked. Any ideas what I could be doing wrong. Please help! Trying to support more AP's. Thanks in advance.
