Represents the index value that uniquely identifies a WLAN Virtual Radio Interface. The interface identified by a particular value of this index is the same interface as identified by the same value of the ifIndex. Before WTPs contact the AC to get configuration, the operator configures WTP profiles for them. The creation of a WTP profile triggers the system to automatically create a specific number of WTP Virtual Radio Interfaces and add a new row object in the capwapBaseWirelessBindingTable without manual intervention. As most MIB modules use the ifIndex to identify an interface for configuration and statistical data (for example, the IEEE 802.11 MIB module [IEEE.802-11.2007]), it will be easy to reuse other wireless binding MIB modules through the WTP Virtual Radio Interface in the Centralized WLAN Architecture.
