STP, RSTP, and MSTP configuration procedures

Specifying a link type
From the CEE interface, use this command to specify a link type. Specifying the point-to-point
keyword, enables rapid spanning-tree transitions to the forwarding state. Specifying the shared
keyword, disables spanning-tree rapid transitions.
To specify a link type on a CEE interface, perform the following steps:
Enabling port fast
From the CEE interface, use this command to enable port fast on an interface to allow the interface
to quickly transition to the forwarding state. Port fast immediately puts the interface into the
forwarding state without having to wait for the standard forward time. If you enable portfast
bpdu-guard on an interface and the interface receives a BPDU, the software disables the interface
and puts the interface in the ERR_DISABLE state.
This command is only for STP. Use the spanning-tree edgeport command for MSTP and RSTP (see
“Enabling a port (interface) as an edge port” on page 56).
Step Task Command
1. Enter global configuration mode. switch>#config t
Enter configuration commands, one
per line. End with CNTL/Z.
switch(config)#
2. Specify the CEE interface (interface 0/1 is used in
this example).
switch(config)#interface
tengigabitethernet 0/1
switch(conf-if-te-0/1)#
3. Enable the CEE interface. switch(conf-if-te-0/1)#no shutdown
switch(conf-if-te-0/1)#
4. Specify a link type on a CEE interface. The default is
point-to-point.
switch(conf-if-te-0/1)#spanning-tree
link-type {point-to-point | shared}
5. Display the spanning-tree configuration. switch(conf-stp)#do show
spanning-tree
