Commands Set List—Spanning Tree Command Set
CNGE8MS
Commands
Level Description
Example
spanning-tree enable
G
Enable spanning tree
switch(config)#spanning-tree
enable
spanning-tree priority
[0to61440]
G
Configure spanning tree priority parameter
switch(config)#spanning-tree
priority 32767
spanning-tree max-
age [seconds]
G
Use the spanning-tree max-age global
configuration command to change the
interval between messages the spanning
tree receives from the root switch. If a switch
does not receive a bridge protocol data unit
(BPDU) message from the root switch within
this interval, it recomputed the Spanning Tree
Protocol (STP) topology.
switch(config)# spanning-tree
max-age 15
spanning-tree hello-
time [seconds]
G
Use the spanning-tree hello-time global
configuration command to specify the interval
between hello bridge protocol data units
(BPDUs).
switch(config)#spanning-tree
hello-time 3
spanning-tree
forward-time
[seconds]
G
Use the spanning-tree forward-time global
configuration command to set the forwarding-
time for the specified spanning-tree instances.
The forwarding time determines how long
each of the listening and learning states last
before the port begins forwarding.
switch(config)# spanning-tree
forward-time 20
stp-path-cost
[1to200000000]
I
Use the spanning-tree cost interface
configuration command to set the path cost
for Spanning Tree Protocol (STP) calculations.
In the event of a loop, spanning tree considers
the path cost when selecting an interface to
place into the forwarding state.
switch(config)#interface
fastEthernet 2
switch(config-if)#stp-path-
cost 20
