3. Configure ports 1/1/3 and 1/1/4 on Switch D as edge ports, since they are
connected to PCs. This will disable topology change detection on these ports:
SwitchD
(config-if 1/1/1)#
interface 1/1/3
SwitchD
(config-if 1/1/3)#
rapid-spanning-tree edge-port
SwitchD
(config-if 1/1/3)#
interface 1/1/4
SwitchD
(config-if 1/1/4)#
rapid-spanning-tree edge-port
Configuration of Switch E:
1. Enable Rapid Spanning Tree Protocol:
SwitchE
#
config terminal
SwitchE
(config)#
protocol
SwitchE
(cfg protocol)#
rapid-spanning-tree enable
SwitchE
(cfg protocol)#
exit
NOTE
After enabling RSTP on Switch E, all ports of this device will perform, by default,
as edge-ports.
2. Configure ports 1/1/3 and 1/1/4 on Switch E as edge ports, since they are
connected to PCs:
SwitchE
(config)#
interface 1/1/3
SwitchE
(config-if 1/1/3)#
rapid-spanning-tree edge-port
SwitchE
(config-if 1/1/3)#
interface 1/1/4
SwitchE
(config-if 1/1/4)#
rapid-spanning-tree edge-port
Displaying the Configuration of Switch D:
