STP, RSTP, and MSTP configuration procedures

Specifying restrictions for an MSTP instance
From the CEE interface, use this command to specify restrictions on the interface for an MSTP
instance. This command is only for MSTP.
To specify restrictions for an MSTP instance on a CEE interface, perform the following steps:
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 restrictions for an MSTP instance on a CEE
interface. Syntax is as follows:
• instance_id—Specifies the MSTP instance. The
range is 1 through 15.
• cost—Specifies the path-cost. The range is 1
through 20000000. The default is 2000.
• priority—Specifies the port priority for a bridge
in increments of 16. The range is 0 through
240.
• restricted-role—Restrict the role of the port.
• restricted-tcn—Restrict the propagation of the
topology change notifications from a port.
switch(conf-if-te-0/1)#spanning-tree
instance instance-id {cost cost |
priority priority | restricted-role
| restricted-tcn}
5. Display the spanning-tree configuration. switch(conf-stp)#do show
spanning-tree
