Hi,
I had a problem with joining my new AP 2700 to the controller. I've found workaround but I would like to ask you if you know if this behavior is a some kind of bug or maybe feature
I have DHCP server which assigns IP address base on the binding MAC address with the IP address. Without binding, IP won't be assigned so I added MAC address from the AP sticker (MAC and SN number is on the sticker at the back of each AP) to the DHCP, connected AP to the switch port which was configured exactly the same way like other ports on this switch where older AP are working fine and.... nothing. IP address was not assigned. There was no DHCP request in the DHCP server logs.
During the investigation I've found that AP present 2 MAC addresses on the switch interface:
switch#sh mac address-table interface fa1/1 Mac Address Table ------------------------------------------- Vlan Mac Address Type Ports ---- ----------- -------- ----- 11 58f3.54c1.2cb3 DYNAMIC Fa1/1 11 58f3.54c1.2cb4 DYNAMIC Fa1/1
The first one (58f3.54c1.2cb3) is a "sticker" MAC address but the second one (58f3.54c1.2cb4) is something new. Looking in to the DHCP logs I've found log that this second MAC address (58f3.54c1.2cb4) tried to get IP address but it was not possible because this MAC was not binding with any IP address so DHCP server refuse. I added this second MAC (58f3.54c1.2cb4) to the DHCP server, AP get IP address, join to the WLC, download software, reboot and ... this MAC address disappear.
switch#sh mac address-table interface fa1/1 Mac Address Table ------------------------------------------- Vlan Mac Address Type Ports ---- ----------- -------- ----- 11 58f3.54c1.2cb3 DYNAMIC Fa1/1
Software I had on the AP before joining to the WLC was:
Version : Cisco IOS Software, C2700 Software (AP3G2-RCVK9W8-M), Version 15.2(4)JB5, RELEASE SOFTWARE (fc1)
now I have (after downloaded from the WLC)
Version : Cisco IOS Software, C2700 Software (AP3G2-K9W8-M), Version 15.2(4)JB6, RELEASE SOFTWARE (fc1)
Do anyone know what happen?
Solved! Go to Solution.

It's look like AP doesn't allow for console login or commands it just only show activity. After rebooting the WLC I get information:
Cisco IOS Software, C2700 Software (AP3G2-RCVK9W8-M), Version 15.2(4)JB5, RELEASE SOFTWARE (fc1)

Why not? The AP hasn't joined the controller yet so this means the username/password is still the default "Cisco/Cisco".

I don't have access to the AP directly, engineer whom I'm taking with told me that he can see output from the AP but AP didn't react on the keyboard.
