show interfaces redundancy



(M Series, T Series, and MX Series routers only) Display general information about redundancy for aggregated multiservices (AMS) interfaces configured for warm standby, adaptive services and link services intelligent queuing (IQ) interfaces, aggregated Ethernet interfaces redundancy, and LNS aggregated inline service interfaces.


When you run the show interfaces redundancy command on an MX80 router, it displays the error message, error:the redundancy-interface-process subsystem is not running. This is because an MX80 router does not have a redundant FPC and does not support link protection.

Table 1: show interfaces redundancy Output Fields

Field Name

Field Description

Level of Output


Name of the AMS interface, redundant adaptive services, link services IQ interfaces, aggregated Ethernet interfaces, or LNS aggregated inline service interfaces.

All levels


State of the redundant interface: Not present, On primary, On secondary, or Waiting for primary MS PIC.

All levels

Last Change

Timestamp for the last change in status. This value resets after a primary Routing Engine switchover event if any of the following conditions is met:

  • GRES is not configured on the router.

  • The rlsq interface is configured without the hot-standby or warm-standby statements and the backup lsq interface was active before the switchover.

  • No logical interfaces are configured or all of the configured logical interfaces are down at the time of the switchover.

All levels


Name of the interface configured to be the primary interface.

All levels


Name of the interface configured to be the backup interface.

All levels

Current Status

Physical status of the primary and secondary interfaces.

All levels


Standby mode.
