Output Fields

Table 1 describes the output fields for the show link-management command. Output fields are listed in the approximate order in which they appear.

Field Name

Field Description

Peer Name

Name of the peer.

System identifier

Internal identifier for the peer. The range of values is 0 through 64,000.

State

State of the peer: Up or Down.

Control address

Address to which a control channel is established.

CC local ID

Identifier assigned to the control channel by the local peer. The range of values is 1 through 4,294,967,296.

CC remote ID

Identifier assigned to the control channel by the remote peer. The range of values is 1 through 4,294,967,296.

State

State of the control channel: Up or Down.

TxSeqNum

Sequence number of the hello message being sent to the peer. The range of values is 1 through 4,294,967,295.

RcvSeqNum

Sequence number of the last hello message received from the peer. The range of values is 0 through 4,294,967,295.

Flags

Code that provides information about the control channel. Currently supports only code value R, which indicates that the control channel is restarting after a failure in the control plane, as when the Link Management Protocol (LMP) process starts or restarts.

TE links

Traffic-engineered links that are managed by their peer.

TE link name

Name of the traffic-engineered link.

State

State of the traffic-engineered link: Up, Down, or Init.

Local identifier

Identifier of the local side of the link.

Remote identifier

Identifier of the remote side of the link.

Local address

Address of the local side of the link.

Remote address

Address of the remote side of the link.

Encoding

Physical layer media type determined by the interfaces contained in the traffic-engineered link. Typical values include SDH/SONET, Ethernet, Packet, and PDH.

Switching

Type of switching that can be performed on the traffic-engineered link. Supported values are PSC-1 and Packet.

Minimum bandwidth

Smallest single allocation of bandwidth possible on the traffic-engineered link. This number is equal to the smallest bandwidth interface that is a member of the traffic-engineered link (in bps).

Maximum bandwidth

Largest single allocation of bandwidth possible on the traffic-engineered link. This number is equal to the largest bandwidth interface that is a member of the link (in bps).

Total bandwidth

Sum of the bandwidth, in bits per second (bps) and megabits per second (Mbps), of all interfaces that are members of the link.

Available bandwidth

Sum of the bandwidths of all interfaces that are members of the link and that are not yet allocated (in bps).

Name

Name of the interface.

State

State of the interface: Up or Down.

Local ID

Identifier of the local side of the interface.

Remote ID

Identifier of the remote side of the interface.

Bandwidth

Bandwidth, in bps or Mbps, of the member interface.

Used

Whether the resource is allocated to an LSP: Yes or No.

LSP-name

LSP name.
