ERS4550T-1: Step 2 – Configure RSTP Edge Ports
4550T-1(config)# interface fastEthernet 5
4550T-1(config-if)# spanning-tree rstp edge-port true
4550T-1(config-if)# exit
ERS4528GT-2: Step 2 – Configure RSTP Edge Ports
4548GT-2(config)# interface fastEthernet 5
4548GT-2(config-if)# spanning-tree rstp edge-port true
4548GT-2(config-if)# exit
2.1.3 Optional RSTP Port Priority Configuration
If we wish to influence the forwarding path when there is more than one link between two switches, the
default RSTP port priority setting can be changed from the default setting of 128 to a lower value in
increments of 16. For example, since 8600-1 is the root bridge and has two links available to 8600-2, if
we wish to use port 4/24, we can simply change the port priority from the default setting of 128 to 16 as
shown below.
ERS8600-1: Step 1 – Change port priority setting on port 4/24
ERS8600-1:5(config)# interface fastEthernet 4/24
ERS8600-1:5(config-if)# spanning-tree rstp priority 16
ERS8600-1:5(config-if)# exit

2.2.1 Verify RSTP Configuration and Root Bridge
Step 1 – Verify that the RSTP is enabled and priority is set to 4096 on 8600-1 and 8192 on 8600-2 to
make 8600-1 the root bridge and 8600-2 the backup root bridge
