Configuring STP, RSTP, or MSTP on CEE interface ports 5 4. Enter the spanning-tree command to specify the restrictions for an MSTP instance on a CEE interface. switch(conf-if-te-0/1)#spanning-tree instance 5 cost 3550 restricted-tcn 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. The default setting is point-to-point. To specify a link type on a CEE interface, perform the following steps from Privileged EXEC mode. 1. Enter the configure terminal command to enter global configuration mode. 2. Enter the interface command to specify the CEE interface type and slot/port number. switch(config)#interface tengigabitethernet 0/1 3. Enter the no shutdown command to enable the CEE interface. 4. Enter the spanning-tree command to specify the link type on the CEE interface. switch(conf-if-te-0/1)#spanning-tree link-type shared Enabling port fast (STP) 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. NOTE If you enable the portfast bpdu-guard option on an interface and the interface receives a BPDU, the software disables the interface and puts the interface in the ERR_DISABLE state. Use the spanning-tree edgeport command for MSTP and RSTP (see "Enabling a port (interface) as an edge port" on page 65). To enable port fast on the CEE interface for STP, perform the following steps from Privileged EXEC mode. 1. Enter the configure terminal command to enter global configuration mode. 2. Enter the interface command to specify the CEE interface type and slot/port number. switch(config)#interface tengigabitethernet 0/1 3. Enter the no shutdown command to enable the CEE interface. 4. Enter the spanning-tree command to enable port fast on the CEE interface. switch(conf-if-te-0/1)#spanning-tree portfast Specifying the port priority From the CEE interface, use this command to specify the port priority. The range is 0 through 240 in increments of 16. The default is 128. Converged Enhanced Ethernet Administrator's Guide 67 53-1001346-01

Configuring STP, RSTP, or MSTP on CEE interface ports
5
4.
Enter the
spanning-tree
command to specify the restrictions for an MSTP instance on a CEE
interface.
switch(conf-if-te-0/1)#
spanning-tree instance 5 cost 3550 restricted-tcn
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. The default setting is point-to-point.
To specify a link type on a CEE interface, perform the following steps from Privileged EXEC mode.
1.
Enter the
configure terminal
command to enter global configuration mode.
2.
Enter the
interface
command to specify the CEE interface type and slot/port number.
switch(config)#
interface tengigabitethernet 0/1
3.
Enter the
no shutdown
command to enable the CEE interface.
4.
Enter the
spanning-tree
command to specify the link type on the CEE interface.
switch(conf-if-te-0/1)#
spanning-tree link-type shared
Enabling port fast (STP)
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.
NOTE
If you enable the
portfast bpdu-guard
option on an interface and the interface receives a BPDU, the
software disables the interface and puts the interface in the ERR_DISABLE state.
Use the
spanning-tree edgeport
command for MSTP and RSTP (see
“Enabling a port (interface) as
an edge port”
on page 65).
To enable port fast on the CEE interface for STP, perform the following steps from Privileged EXEC
mode.
1.
Enter the
configure terminal
command to enter global configuration mode.
2.
Enter the
interface
command to specify the CEE interface type and slot/port number.
switch(config)#
interface tengigabitethernet 0/1
3.
Enter the
no shutdown
command to enable the CEE interface.
4.
Enter the
spanning-tree
command to enable port fast on the CEE interface.
switch(conf-if-te-0/1)#
spanning-tree portfast
Specifying the port priority
From the CEE interface, use this command to specify the port priority. The range is 0 through 240 in
increments of 16. The default is 128.
