STP, RSTP, and MSTP configuration procedures

Disabling or enabling spanning tree
From the CEE interface, use this command to disable or enable spanning tree on the CEE interface.
To disable or enable spanning tree on the CEE interface, perform the following steps:

Flushing MAC addresses
For RSTP and MSTP, use this command to flush the MAC addresses from the VLAN filtering
database (FDB). The VLAN FDB determines the forwarding of an incoming packet. The VLAN FDB
contains information that helps determine the forwarding of an arriving frame based on MAC
address and VLAN ID data (see “VLAN configuration guidelines and restrictions” on page 27).
There are two ways to flush the MAC addresses:
• Standard method—When one port receives a BPDU packet with a topology change flag, it
flushes the FDB for the other ports in the switch. If a BPDU packet with the topology change
flag is received continuously, the switch continues to flush the FDB. This behavior is the default
behavior and is activated by entering the spanning-tree tc-flush-standard command.
• Brocade method—To avoid the continuous flushing that you get with the standard method,
enter the no spanning-tree tc-flush-standard command. With this method, the FDB is only
flushed for the first and last BPDU that has a topology change flag.
Both methods flush the FDB when the switch receives BPDUs with a topology change flag, but the
Brocade method causes less flushing.
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. Disable or enable spanning tree on the CEE
interface. By default, spanning tree is disabled. Use
the no spanning-tree shutdown command to enable
spanning tree on the CEE interface.
switch(conf-if-te-0/1)#spanning-tree
shutdown
5. Display the spanning-tree configuration. switch(conf-stp)#do show
spanning-tree
