root switch within this interval,
it recomputed the Spanning
Tree Protocol (STP) topology.
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
stp-admin-non-stp I
Admin NonSTP of STP priority
switch(config)#interface fastEthernet 2
