Strict Active/Standby Interface Backup With The Track Module Configuration Example - HP MSR Series Configuration Manual

# Specify GigabitEthernet 2/0/2 and GigabitEthernet 2/0/3 to back up GigabitEthernet 2/0/1,
and assign them a priority of 30 and 20, respectively.
[RouterA] interface gigabitethernet 2/0/1
[RouterA-GigabitEthernet2/0/1] backup interface gigabitethernet 2/0/2 30
[RouterA-GigabitEthernet2/0/1] backup interface gigabitethernet 2/0/3 20
# Set both up and down delay timers to 10 seconds.
[RouterA-GigabitEthernet2/0/1] backup timer delay 10 10
Verifying the configuration
# Display states of the primary and backup interfaces.
[RouterA-GigabitEthernet2/0/1] display interface-backup state
Interface: GE2/0/1
UpDelay: 10 s
DownDelay: 10 s
State: UP
Backup interfaces:
GE2/0/2
GE2/0/3
The output shows that GigabitEthernet 2/0/1 is in UP state and the two backup interfaces are in
STANDBY state.
# Shut down the primary interface GigabitEthernet 2/0/1.
[RouterA-GigabitEthernet2/0/1] shutdown
# Verify that the backup interface GigabitEthernet 2/0/2 comes up 10 seconds after the primary
interface goes down.
[RouterA-GigabitEthernet2/0/1] display interface-backup state
Interface: GE2/0/1
UpDelay: 10 s
DownDelay: 10 s
State: DOWN
Backup interfaces:
GE2/0/2

As shown in
the link of GigabitEthernet 2/0/1 fails, the backup interface GigabitEthernet 2/0/2 comes up to take
over.
