Syntax

Release Information

Command introduced in Junos OS Release 13.2.

Support for logical systems added in Junos OS Release 14.1.

Command introduced in Junos OS Release 15.1R1 for EX Series switches

Description

(MX Series routers only) Display ARP statistics, Neighbor Discovery statistics, or remote MAC addresses for the Multi-Chassis Aggregated Ethernet (MC-AE) nodes for all or specified redundancy groups on a router or switch or logical systems on a router or switch. Note that the Redundancy Group ID is inherited by the bridging domain or VLAN from member AE interfaces.

Options

logical-system [system-name | all](Optional) Display information for a specified logical system or all systems.
redundancy-group-id(Optional) The redundancy group identification number. The Inter-Chassis Control Protocol (ICCP) uses the redundancy group ID to associate the routing or switching devices contained in a redundancy group.
arp-statistics(Optional) Count of ARP packets sent and received by the two MC-AE nodes.
nd-statistics(Optional) Count of Neighbor Discovery packets sent and received by the two MC-AE nodes.
remote-macs (Optional) List of remote MAC addresses in the “Installed” state, as learned from the remote MC-AE node.
