Failover Conditions

The following describes the conditions under which the primary line card will fail over to the secondary
line card when line card redundancy is configured.

removes one-to-one redundancy between two 4-Port Channelized T3 Half-Height line
Removing Line Card Redundancy
User-initiated switchover—You have performed a manual switchover using the redundancy
linecard-group switchover from subslot command.
Line card-initiated switchover—The line card detects a failover condition and sends a cutover
interrupt to the performance routing engine (PRE).
PRE-initiated OIR switchover—The PRE detects the removal of the primary line card.
PRE-initiated keepalive timeout switchover—More than 20 seconds have elapsed since the PRE
received a keepalive message from the line card.

Purpose
Removes the redundancy role of the secondary (standby) line
card.
You must remove redundancy from the secondary line card
before removing redundancy from the primary line card.
Removing redundancy resets the line card (traffic is
Note
interrupted) and applies the default configuration to the
line card. If you remove redundancy from the secondary
line card only, traffic is not interrupted through the
primary line card.
(Optional) Removes the redundancy role of the primary (active)
line card.
You must remove redundancy from the secondary line card
before removing redundancy from the primary line card.
Note Removing redundancy resets the line card (traffic is
interrupted) and applies the default configuration to the
line card. If you remove redundancy from the secondary
line card only, traffic is not interrupted through the
primary line card.
Returns to redundancy mode.
