When the spanning tree topology is completed, the network switches send and receive data only on
the ports that are part of the spanning tree. Data received on ports that are not part of the spanning
tree is blocked.
NOTE
Brocade recommends leaving other STP variables at their default values.
For more information on STP, refer to
Configuring and managing STP and STP variants
412.
Configuring RSTP
The basic process for configuring RSTP is as follows.
1. Enter the configure terminal command to change to global configuration mode.
switch# configure terminal
2. Enable RSTP by using the global protocol spanning-tree command. For details, refer to
STP, RSTP, MSTP, PVST+ or R-PVST+
on page 419.
switch(config)# protocol spanning-tree rstp
3. Designate the root switch by using the bridge-priority command. For more details, refer
to
Specifying the bridge priority
on page 420. The range is 0 through 61440 and the priority values
can be set only in increments of 4096.
switch(conf-stp)# bridge-priority 28582
4. Configure the bridge forward delay value. For more details, refer to
switch(conf-stp)# forward-delay 20
5. Configure the bridge maximum aging time value. For more details, refer to
switch(conf-stp)# max-age 25
6. Enable the error disable timeout timer value. For more details, refer to
on page 422.
switch(conf-stp)# error-disable-timeout enable
7. Configure the error-disable-timeout interval value. For more details, refer to
switch(conf-stp)# error-disable-timeout interval 60
8. Configure the port-channel path cost. For more details, refer to
Specifying the port-channel path cost
on page 423.
switch(conf-stp)# port-channel path-cost custom
9. Configure the bridge hello-time value. For more details, refer to
Specifying the bridge hello time
page 422.
switch(conf-stp)# hello-time 5
10.Enable port fast on switch ports by using the spanning-tree portfast command. For more details,
refer to
