Step 2 Verify the configuration.
After the previous configurations, run the following commands to verify the configuration when
the network is stable:
# Run the display stp brief command on SwitchA to view the interface status and protection
type. The displayed information is as follows:
[SwitchA] display stp brief
MSTID Port Role STP State Protection
0 GigabitEthernet1/0/1 DESI FORWARDING NONE
0 GigabitEthernet1/0/2 DESI FORWARDING NONE
After SwitchA is configured as a root bridge, GE 1/0/2 and GE 1/0/1 connected to SwitchB and
SwitchD respectively are elected as designated ports in spanning tree calculation.
# Run the display stp interface gigabitethernet 1/0/1 brief command on SwitchB to view status
of GE 1/0/1. The displayed information is as follows:
[SwitchB] display stp interface gigabitethernet 1/0/1 brief
MSTID Port Role STP State Protection
0 GigabitEthernet1/0/1 DESI FORWARDING NONE
GE 1/0/1 is elected as a designated port in spanning tree calculation and is in the Forwarding
state.
# Run the display stp brief command on SwitchC to view the interface status and protection
type. The displayed information is as follows:
[SwitchC] display stp brief
MSTID Port Role STP State Protection
0 GigabitEthernet1/0/1 ALTE DISCARDING NONE
0 GigabitEthernet1/0/3 ROOT FORWARDING NONE
GE 1/0/1 is elected as an alternate port in spanning tree calculation and is in the Discarding state.
