Introduction : For IEEE 802.1X Authenticators, the attribute called-station-id is used to store the bridge or Access Point MAC address(upper or lower case) with octet values separated by a none(default)/colon/dash/none. Example with upper case with dash: "00-10-A4-23-19-C0".
In IEEE 802.11, where the SSID is known, it should be appended to the Access Point MAC address, separated from the MAC address with colon(default)/dash/none. Example with colon: 00-10-A4-23-19-C0 : ARUBA
Feature Notes : This feature helps in appending SSID information in the Radius request to the attribute called-station-id and this feature is supported from Aruba OS 6.4
Environment : Product & Software: This article applies to Aruba OS 6.4 and above.
Configuration Steps :
To configure the called-sation-id, navigate to Configuration > Security > Authentication > Servers
Select the radius server and configure the called-station-id
To configure in command line interface, the below commands show to configure mac address with SSID as part of the called-station-id.
(Aruba) (config) #aaa authentication-server radius Guest
(Aruba) (RADIUS Server "Guest") #called-station-id type macaddr include-ssid enable delimiter colon
ap-group Send AP group as called station id
ap-macaddr Send AP mac address as called station id
ap-name Send AP name as called station id
ipaddr Send controller ip address as called station id
macaddr Send controller mac address as called station
vlan-id Send VLAN index as called station id
We have the option to configure, ap-group/ap-macaddr/ap-name/ipaddr/macaddr or vlan-id and include or exclude ssid information in the called-station-id.
In this sample, SSID ARUBA has been appended to the Access Point MAC address.
In the Radius Access-Request, called-station-id attribute SSID ARUBA has been appended to AP Mac address.
