Configuring the Role in Radio Network
Radio Tracking
You can configure the access point to track or monitor the status of one of its radios. It the tracked radio
goes down or is disabled, the access point shuts down the other radio. If the tracked radio comes up, the
access point enables the other radio.
•To track radio 0, enter the following command:
# station-role root access-point fallback track d0 shutdown
•To track radio 1, enter the following command:
# station-role root access-point fallback track d1 shutdown
Note This command is not supported by 802.11n series access points (such as AP1260), you must use the
following command in the radio interface configuration mode:
# station-role root access-point fallback shutdown
Fast Ethernet Tracking
You can configure the access point for fallback when its Ethernet port is disabled or disconnected from
the wired LAN. You configure the access point for fast Ethernet tracking as described in the
“Configuring the Role in Radio Network” section on page6-2.
Note Fast Ethernet tracking does not support the Repeater mode.
•To configure non-802.11n access points for Fast Ethernet tracking, in the radio interfaces
configuration mode enter the following command:
# station-role root access-point fallback track fa 0
•To configure 802.11n access points (such as AP1040, AP1140, AP1250, and AP1260) for Gigabit
Ethernet tracking, in the radio interfaces configuration mode enter the following command:
# station-role root fallback shutdown
MAC-Address Tracking
You can configure the radio whose role is root access point to go up or down by tracking a client access
point, using its MAC address, on another radio. If the client disassociates from the access point, the root
access point radio goes down. If the client reassociates to the access point, the root access point radio
comes back up.
MAC-address tracking is most useful when the client is a non-root bridge access point connected to an
upstream wired network.
For example, to track a client whose MAC address is 12:12:12:12:12:12, enter the following command:
# station-role root access-point fallback track mac-address 12:12:12:12:12:12 shutdown
