G
parameter
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
G 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.
Use the spanning-tree hello-time
global configuration command to
specify the interval between hello
G
bridge protocol data units
(BPDUs).
[seconds] Use the spanning-tree forward-
time global configuration command
to set the forwarding-time for the
specified spanning-tree instances.
G
The forwarding time determines
how long each of the listening and
learning states last before the port
begins forwarding.
Use the spanning-tree cost
interface configuration command
to set the path cost for Spanning
Tree
Protocol (STP) calculations. In the
I
event of a loop, spanning tree
considers the path cost when
selecting
an interface to place into the
forwarding state.
Use the spanning-tree port-priority
interface configuration command
I
to configure a port priority that
is used when two switches tie for
