Conceptual table for WEP Key Mappings. The MIB supports the ability to share a separate WEP key for each RA/TA pair. The Key Mappings Table contains zero or one entry for each MAC address and contains two fields for each entry: WEPOn and the corresponding WEP key. The WEP key mappings are logically WRITE-ONLY. Attempts to read the entries in this table shall return unsuccessful status and values of null or zero. The default value for all WEPOn fields is false.
