Output Field Name

Field Description

Member Link

Identifiers of the configured multichassis link aggregate interfaces configured interfaces.

Current State Machine’s State

Current state of the MCLAG state machine. The MCLAG state machine is responsible for synchronization with the peer MCLAG node.

Local Status

Status of the local link: active or standby.

Peer Status

Status of the peer link: active or standby.

Local State

Up or down state of the local device.

Peer State

Status of the local and peer links in an active/active bridge or VRRP over integrated routing and bridging (IRB) configuration on MX Series routers, including:

Logical InterfaceAggregated Ethernet (AE) aggregate number and unit number.
Topology TypeThe bridge or VRRP topology type configured on the AE.
Local StateUp or down state of the local device.
Peer StateUp or down state of the peer device.
Peer Ip/ICL-PL/StateAddress, interface and state of the peer device.

Core Facing Interface

Label: pseudowire interface or Ethernet interface.

ICL-PL

Label: pseudowire interface or Ethernet interface.

switchover mode

The configured switchover mode for the multichassis aggregated Ethernet interface: revertive or non-revertive.

switchover status

Status of the switchover if the revert-time statement is configured at the [edit interfaces aex mc-ae] hierarchy level.

revert time

Revert time configured for the multichassis aggregated Ethernet interface.

switchover time remaining

Seconds left to trigger the switchover if the switchover is in progress.

Configuration Error Status

Reason for the configuration error.

MCAE Configuration

Redundancy Groups

Identification number of the redundancy group. The Inter-Chassis Control Protocol (ICCP) uses the redundancy group ID to associate multiple chassis that perform similar redundancy functions. Possible values: 1 through 4,294,967,294.

MCAE ID

Identification number of the MC-LAG device. The two MC-LAG network devices that manage a given MC-LAG must have the same identification number. Possible values:1 through 65,535.

MCAE Mode

Specifies whether the MC-LAG is in active-active or active-standby mode. Possible values: active-active or active-standby.

Status Control

Specifies whether the chassis becomes active or remains in standby mode when an interchassis link failure occurs. Possible values: active or standby.

Chassis ID

Chassis ID for Link Aggregation Control Protocol (LACP) to calculate the port number of MC-LAG physical member links. Possible values: 0 or 1.

LACP Configuration

System ID

System id of the local system.

Admin Key

LACP administrative key of the node. Value should be the same on both MCLAG peers.

LACP Information

Local Partner System ID

LACP partner system ID as seen by the local node.

Peer Partner System ID

LACP partner system ID as seen by MC-AE peer node.
