Spanning Tree Commands Set
Allied Telesis 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
32768
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
the forwarding state.
switch(config)#interface fastEthernet 2
switch(config-if)#stp-path-cost 20
