Hey Everyone,
after viewing the forum and seeing some issues with the AP 275 radios not coming up I thought I would share the solution to our install.
Implementation:
AP 275 -> PowerDsine 9001GO -> Alcatel 7210 SAS D
Issue:
AP was connecting to the controller but the AP's were giving the following error.
Power Status
------------
Operational State POE-AF: Ethernet port 1 disabled; All radios disabled;
----------------- ------------------------------------------------------
Current HW State POE-AF: Ethernet port 1 disabled; All radios disabled;
LLDP Negotiated POE Power 0.0W
Solution:
By default the port setting have an mtu of 1518, 1522, etc (based on encapsulation). It was noted that on other AP 275's that worked the minimum MTU size was 1558. The AP's did come up but the radios remained down until we adjusted the port MTU (we selected 1560). Once the MTU was changed the radios were able to come up within a minute. Hopefully this can help someone in the future.
Cheers
