To confirm that the configuration is working properly, perform these tasks:
Verifying RSTP Configuration on Switch 1 on page 1295
Verifying RSTP Configuration on Switch 2 on page 1295
Verifying RSTP Configuration on Switch 3 on page 1296
Verifying RSTP Configuration on Switch 4 on page 1296
Verifying RSTP Configuration on Switch 1
Verify the RSTP configuration on Switch 1.
Use the operational mode command:
user@switch1> show spanning-tree interface
Spanning tree interface parameters for instance 0
Interface Port ID
ge-0/0/13.0 128:527
ge-0/0/9.0 128:529
ge-0/0/11.0 128:531
Refer to the topology in Figure 33 on page 1284. The operational mode command
spanning-tree interface shows that
interfaces on Switch 1 are blocking.
Verifying RSTP Configuration on Switch 2
Verify the RSTP configuration on Switch 2.
Use the operational mode command:
user@switch2> show spanning-tree interface
Spanning tree interface parameters for instance 0
Interface Port ID
