all—(Optional) Display all connections.

brief—(Optional) Display brief connection status information.

down—(Optional) Display connections that are not operational.

extensive—(Optional) Display very detailed connection, labels, and history information.

history—(Optional) Display connection history.

interface-switch—(Optional) Display interface switch connections.

labels—(Optional) Display labels used for transmit and receive LSPs.

lsp-switch—(Optional) Display LSP switch connections.

name—(Optional) Display information about the named connection.

remote-interface-switch—(Optional) Display remote interface switch connections.

status—(Optional) Display connection and circuit status.

up—(Optional) Display connections that are operational.

up-down—(Optional) Display both operational and nonoperational connections.

logical-router logical-router-name—(Optional) Name of a particular logical router on which the command operates.

Output Fields

CCC and TCC connections [Link Monitoring On I Off]—Whether link monitoring is enabled. It can be On or Off.

Legend for Status (St)—Connection or circuit status. See the output's legend for an explanation of the status field values.

• UN—uninitialized
• NP—not present
• WE—wrong encapsulation
• DS—disabled
• Dn—down
• ->—only outbound conn is up
• <-—only inbound conn is up
• Up—operational
• RmtDn—remote CCC down
• Restart—restarting

Legend for connection types—Type of connection:

• if-sw—Layer 2 switching cross-connect.
• rmt-if—Remote interface switch. While graceful restart is in progress, rmt-if will display a state (St) of Restart.
• lsp-sw—LSP stitching cross-connect. While graceful restart is in progress, lsp-sw will display a state (St) of Restart.

Legend for circuit types—Type of circuits:

• intf—Interface circuit.
• tlsp—Transmit LSP circuit.
• rlsp—Receive LSP circuit.

Connection/Circuit—Name of the configured CCC connection.

Time last up—Time that the connection or circuit last transitioned to the Up (operational) state, in the format mon day hh:mm:ss.

# Up trans—Number of times that the connection or circuit has transitioned to the Up (operational) state.
