The below are some of the useful AP commands that could be used to check various parameters on the AP.

boarddata display : This command shows the AP inbuilt properties like network details, Serial number of each radio interface, boot delay for a AP, Ethernet address of the AP, AP Model number, AP part number, AP serial Number etc.,

cie show : This command will show country specific information for the AP. The details include Number Of Allowed Channels per band ( A & BG ), Starting Channel Number for each band, TX power for each channel in the band.

config : This has a wide range of options that could be configured for the APs, they are

config set {radio|ethernet|ap} <parameter> <name> : set configuration parameters.
config set radio <if> admin {up|down|testing}
config set radio <if> channel <channel>
config set radio <if> width {20|auto}
config set radio <if> mode <A|B|G|BG|BGN|AN>
config set radio <if> antenna {1|2|internal|external|diversity}
config set radio <if> power {low|medium|high} <powerlvl>
config set radio <if> scan <space separated channel list>
config set radio <if> protection <none|cts|rts-cts|dual-speed>
config set radio <if> protection-mode <on|off|auto>
config set ethernet mac <mac address>
config set ap name <AP name>
config set ap id <ap node id>
config set ats loopbacktesthook <enable|disable> magic_num <on|off>ip <ip addr> mac <mac addr, : separated>
config show radio|ethernet|ap   :      show configuration parameters.
config show ap                           :      display global ap parameters.
config show ethernet                 :      display ethernet parameters.
config show radio <radio-name> :    display radio parameters.
config show ats loopbacktesthook : display ats loopbacktesthook status.

flashcmds show : This command is used to show all the logs of the AP which will be required while troubleshooting the AP reboot issue. Also these logs are helpful in understanding the booting process of the APs.

history : Displays a list of previously used commands in the AP.

exit : To exit out of the AP and go back to the controller.

ip arp -a : To print all the entries in the ARP cache.

ip config : To configure the AP manually in regards to connectivity and network setting, below are the options available

 ip config <save | write>  : Save the IP configuration to non-volatile memory.

 ip config <reset | clear>  : Reset/Clear the IP configuration to factory defaults.

 ip config name <name>  : Configure the AP name.

ip config address <address> : Configure the AP IP address.

ip config netmask <netmask> : Configure the AP netmask.

ip config gateway <netmask>  : Configure the gateway.

ip config controller name <name> : Configure controller name.

ip config controller domain <name> : Configure controller domain.

ip config net <static | dhcp | none> : Configure Net for DHCP, static, or none.

ip config l2l3 <l2only | l2preferred | l3preferred | l3experimental > : Configure l2l3 Rx/Tx network layer.

ip config dns add <address> : Add DNS server.

ip config dns remove <address> : Remove DNS server.

ip info : Display all the ip information of the AP.

radio keycache radio0 : Show the key cache of the AP for the radio 0 interface ( 2.4 Ghz )

radio keycache radio1  : Show the key cache of the AP for the radio 1 interface ( 5 Ghz )

radio stats radio0 : Show the complete statistic of the AP for the radio 0 ( 2.4 Ghz )

radio stats radio1 : Show the complete statistic of the AP for the radio 1 ( 5 Ghz )

radio show radio0 : Will show the configuration and parameter for this AP radio 0

radio show radio1 : Will show the configuration and parameter for this AP radio 1 
 

Sniff : To enable the AP for a sniffing function. ( basically used for taking capture of packets over the air line an airopeek card)

stadb : This commands is used for displayed the station database details and it has the following options,
