[seconds]
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.
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
stp-path-priority
[Port Priority]
I
Use the spanning-tree
port-priority interface
configuration command to
configure a port priority
that is used when two
switches tie for position as
the root switch.
switch(config)#
interface fastEthernet
2
switch(config-if)#
stp-path-priority
128
stp-admin-p2p
[Auto|True|False]
I
Admin P2P of STP priority
on this interface.
switch(config)#
interface fastEthernet
2
switch(config-if)#
stp-admin-p2p Auto
stp-admin-edge
[True|False]
I
Admin Edge of STP priority
on this interface.
switch(config)#
interface fastEthernet
2
switch(config-if)#
stp-admin-edge
True
