3.5 Spanning Tree Commands Set
Netstar Commands Level Description Example
spanning-tree enable G Enable spanning tree. switch(config)#spanning-tree enable
spanning-tree priority
[0~61440]
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
[1~200000000]
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 switch(config)#interface fastEthernet 2
switch(config-if)#stp-path-cost 20
