Configuring STP/RSTP
13-11
Enabling or Disabling STP on a Port
If you enable STP on a VLAN, the change does not affects all ports belong to the VLAN.
Therefore you should enable STP on all Ethernet ports within the VLAN.
To enable STP on a port, perform this task in Privileged mode:
Table 13-5 Enabling STP on a port
Command Task
configure terminal 1. Enter global configuration mode.
port <port-type>
<slot>/ <port> stp
2. Enable STP on a specific Ethernet port.
y <port-type> : The type of Ethernet port to enable STP on.
- fastethernet
: Fast Ethernet port
- gigabitethernet
: Gigabit Ethernet port
y <slot>/<port> : The slot number and port number of the
Ethernet port.
end 3. Return to privileged mode.
show stp port <port-type>
<slot>/<port>
4. Verify the STP configuration.
y <port-type> : The type of Ethernet port
- fastethernet
: Fast Ethernet port
- gigabitethernet
: Gigabit Ethernet port
y <slot>/<port> : The slot number and port number of the
Ethernet port.
The following example enables STP on the port 1/1 and 2/1:
(config)# port gigabitethernet 1/1 stp
(config)# port fastethernet 2/1 stp
(config)# end
# show stp port fastethernet 2/1
Link State: up
Protocol Operation: enabled
