STP and RSTP Commands
Use these commands to configure Spanning Tree Protocol (STP) and Rapid Spanning Tree
Protocol (RSTP) as defined in the following standards.
• IEEE 802.1D Spanning Tree Protocol
• IEEE 802.1w Rapid Spanning Tree Protocol
for more information on MRSTP and
MSTP commands respectively. See also
for information on loopguard
commands.

COMMAND
DESCRIPTION
M
P
show spanning-tree config
Displays Spanning Tree Protocol (STP) settings.
E
3
spanning-tree mode
Specifies the STP mode you want to implement on the
Switch.
C
13
spanning-tree
Enables STP on the Switch.
C
13
no spanning-tree
Disables STP on the Switch.
C
13
spanning-tree hello-time <1-10>
maximum-age <6-40> forward-delay
<4-30>
Sets Hello Time, Maximum Age and Forward Delay.
hello-time: The time interval in seconds between BPDU
(Bridge Protocol Data Units) configuration message
generations by the root switch.
maximum-age: The maximum time (in seconds) the Switch
can wait without receiving a BPDU before attempting to
reconfigure.
forward-delay: The maximum time (in seconds) the
Switch will wait before changing states.
C
13
spanning-tree priority <0-61440> Sets the bridge priority of the Switch. The lower the numeric
value you assign, the higher the priority for this bridge.
priority: Must be a multiple of 4096.
C
13
spanning-tree <port-list>
Enables STP on a specified ports.
C
13
no spanning-tree <port-list>
Disables STP on listed ports.
C
13
spanning-tree <port-list> path-
cost <1-65535>
Specifies the cost of transmitting a frame to a LAN through
the port(s). It is assigned according to the speed of the
bridge.
