This field indicates the type of control channel advertised by the peer to this node. This object is configurable only for manual mode of pseudowire (i.e., when pseudowire signaling is not used). This object acts as read-only object for signaling type of pseudowires. Only matching capabilities can be selected from the remote CC type. When multiple capabilities match, only one CC Type MUST be used. For cases where multiple CC Types are advertised, the following precedence rules apply while choosing the single CC Type for use: 1. Type 1: PWE3 Control Word with 0001b as first nibble 2. Type 2: MPLS Router Alert Label 3. Type 3: MPLS PW Label with TTL == 1 Value of this object cannot be changed when pwRowStatus is active.
