# Set the upper and lower thresholds to 80 and 20, respectively.

[RouterA-Serial2/1/0] backup threshold 80 20

# Display traffic statistics for load-shared interfaces.

[RouterA-Serial2/1/0] display interface-backup statistics

Interface: Serial2/1/0

Statistics interval: 30 s

Bandwidth: 10000000 bps

PrimaryTotalIn: 102 bytes

PrimaryTotalOut: 108 bytes

PrimaryIntervalIn: 102 bytes

PrimaryIntervalOut: 108 bytes

Primary used bandwidth: 28 bps

Total used bandwidth: 28 bps

The output shows that the upper traffic threshold has not been exceeded. All traffic is transmitted through

the primary interface Serial 2/1/0.

# Verify that both backup interfaces are in STANDBY state because the upper threshold has not been

exceeded.

[RouterA-Serial 2/1/0] display interface-backup state

Interface: S2/1/0

UpDelay: 0 s

DownDelay: 0 s

Upper threshold: 80

Lower threshold: 20

State: UP

Backup interfaces:

S2/1/1 Priority: 30 State: STANDBY

S2/1/2 Priority: 20 State: STANDBY

# Increase the incoming or outgoing traffic rate to be higher than 8000 kbps (80% of the specified

bandwidth) on the primary interface. (Details not shown.)

# Verify that the backup interface Serial 2/1/1 comes up to participate in traffic forwarding, because it

has higher priority than Serial 2/1/2.
