Checking results
Use the show port backup group command to show status of interface backup under normal
or faulty conditions.
When both GE 1/1/1 and GE 1/1/2 are Forward, GE 1/1/1 forwards traffic of VLANs 100–
150, and GE 1/1/2 forwards traffic of VLANs 151–200.

Manually disconnect the link between Switch A and Switch B to emulate a fault. Then, GE
1/1/1 becomes Down, and GE 1/1/2 forwards traffic of VLANs 100–200.
