An entry in this table MUST be created by the agent for every PW created by the pwTable for which pwOwner equals pwIdFecSignaling. Implementors need to be aware that if the value of the pwIndexMappingPeerAddr (an OID) or pwIndexMappingPwID (an OID) (or both combined) has more than 111 sub-identifiers, then OIDs of column instances in this table will have more than 128 sub-identifiers and cannot be accessed using SNMPv1, SNMPv2c, or SNMPv3.
