Table 1: show interfaces mc-ae Output Fields

Output Field Name	Field Description
Current State Machine’s State	Specifies the state of the MC-LAG initialization state machine.
Member Link	Specifies the identifiers of the configured multichassis link aggregated interface members.
Local Status	Specifies the status of the local link: active or standby.
Peer Status	Specifies the status of the peer link: active or standby.
Peer State	Specifies the status of the local and peer links in an active/active MC-LAG configuration.
Logical Interface	Specifies the identifier and unit of the AE interface.
Topology Type	Specifies the bridge configured on the AE.
Local State	Specifies if the local device is up or down.
Peer State	Specifies if the peer device is up or down.
Peer Ip/MCP/State	Specifies the multichassis protection (MCP) link or the interchassis link-protection link (ICL-PL) for all of the multichassis aggregated Ethernet interfaces that are part of the peer.
