COTD: Find out the speed and duplex that an APs Ethernet port negotiated

[cjoseph]

We all know that endpoint performance is degraded when that station does not negotiate his speed and duplex correctly with a switch. The same issue occurs with an AP that did not negotiate to that switchport correctly. To find out what speed/duplex and AP negotiated to, use the "show ap debug system-status" command and grep for "Ethernet" (case-sensitive):

(Aruba800-4) #show ap debug system-status ap-name ConferenceRoom-1 | begin Ethernet
Ethernet Duplex/Speed Settings
------------------------------
Autoneg  Speed (Mbps)  Duplex  Iface
-------  ------------  ------  -----

You can also substitute the ap-name parameter with ip-addr to query by ap ip address instead.
