Cisco AS5850 Example
The following is sample output from the show redundancy handover and show redundancy states
commands on a Cisco AS5850:
Router# show redundancy handover
No busyout period specified
Handover pending at 23:00:00 PDT Wed May 9 2001
Router# show redundancy states
my state = 14 -ACTIVE_EXTRALOAD
peer state = 4 -STANDBY COLD
Mode = Duplex
Unit = Preferred Primary
Unit ID = 6
Redundancy Mode = Handover-split: If one RSC fails, the peer RSC will take over the
feature boards
Maintenance Mode = Disabled
Manual Swact = Disabled Reason: Progression in progress
Communications = Up
client count = 3
client_notification_TMR = 30000 milliseconds
keep_alive TMR = 4000 milliseconds
keep_alive count = 1
keep_alive threshold = 7
RF debug mask = 0x0
Cisco AS5800 Example
The following is sample output from the show redundancy command on a Cisco AS5800:
Router# show redundancy
DSC in slot 12:
Hub is in 'active' state.
Clock is in 'active' state.
DSC in slot 13:
Hub is in 'backup' state.
Clock is in 'backup' state.
Cisco AS5800 with History Example
The following is sample output from the show redundancy history command on a Cisco AS5800:
Router# show redundancy history
DSC Redundancy Status Change History:
981130 18:56 Slot 12 DSC: Hub, becoming active - RS instruction
981130 19:03 Slot 12 DSC: Hub, becoming active - D13 order
Cisco AS5800 Router Shelves as Failover Pair Example
The following is sample output from two Cisco AS5800 router shelves configured as a failover pair. The
active router shelf is initially RouterA. The show redundancy history and show redundancy
commands have been issued. The show redundancy command shows that failover is enabled, shows the
configured group number, and shows that this router shelf is the active one of the pair. Compare this
output with that from the backup router shelf (RouterB) that follows.
