The value of tmnxOamVccvPingCtlPwId specifies the pseudowire identifier
to be used when performing a vccv-ping operation on a FEC 128
pseudowire. The pseudowire Id is a non-zero 32-bit connection ID
required by FEC 128, as defined in RFC 4379. This object is only valid
when used in conjunction with valid tmnxOamPingCtlTgtAddress and
tmnxOamPingCtlSrcAddress. A value of zero indicates that no pseudowire
Id has been configured.
