•
Disabled—The interface is not participating in spanning tree because of a shutdown port, no
link on the port, or no spanning tree instance running on the port.
A port participating in spanning tree moves through these states:
•
From initialization to blocking.
•
From blocking to listening or to disabled.
•
From listening to learning or to disabled.
•
From learning to forwarding, blocking, or disabled.
•
From forwarding to disabled.
The following STP features are considered optional features although you might use them in your
STP configuration:
•
Root guard—For detailed information, see
•
PortFast BPDU guard and BPDU filter—For detailed information, see
Configuring STP on Dell FCoE hardware
The process for configuring STP on your Dell FCoE hardware is as follows.
1. Enter Global Configuration mode.
2. Enable RSTP using the global protocol spanning-tree command. For details, see
switch(config)#protocol spanning-tree rstp
3. Designate the root switch using the bridge-priority command. For details, see
on page 52. 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. Enable PortFast on switch ports using the spanning-tree portfast command. For details, see
on page 61. Note that this step is optional.
NOTE
PortFast only needs to be enabled on ports that connect to workstations or PCs. Repeat these
commands for every port connected to workstations or PCs. Do not enable PortFast on ports
that connect to other switches.
switch(config)#interface intengigabitethernet 0/10
switch(conf-if-te-0/10)#spanning-tree portfast
switch(conf-if-te-0/10)#exit
switch(config)#interface intengigabitethernet 0/11
switch(conf-if-te-0/11)#spanning-tree portfast
switch(conf-if-te-0/11)#exit
Repeat these commands for every port connected to workstations or PCs.
5. Set the following ports to forwarding mode:
•
All ports of the root switch
•
The root port
•
The designated port
