Configuring STP, RSTP, or MSTP on CEE interface ports

DRAFT: BROCADE CONFIDENTIAL
To specify the port priority on the CEE interface, perform the following steps from privileged EXEC
mode.
1. Enter the configure terminal command to access 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 port priority on the CEE interface.
switch(conf-if-te-0/1)#spanning-tree priority 32
Restricting the port from becoming a root port
From the CEE interface, use this command to restrict a port from becoming a root port. The default
is to allow the CEE interface to become a root port.
To restrict the CEE interface from becoming a root port, perform the following steps from privileged
EXEC mode.
1. Enter the configure terminal command to access 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 restrict the CEE interface from becoming a root port.
switch(conf-if-te-0/1)#spanning-tree restricted-role
Restricting the topology change notification
From the CEE interface, use this command to restrict the topology change notification BPDUs sent
on the interface. By default, the restriction is disabled.
To restrict the topology change notification BPDUs sent on the CEE interface, perform the following
steps from privileged EXEC mode.
1. Enter the configure terminal command to access 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 restrict the topology change notification BPDUs sent on
the CEE interface.
switch(conf-if-te-0/1)#spanning-tree restricted-tcn
Enabling spanning tree
By default, spanning tree is enabled on all switch ports when spanning tree is enabled globally. If it
is shutdown previously on a particular interface, it is saved across all modes of spanning-tree
(STP/RSTP/MSTP).
