Level Description
switch within this interval,
the RSTP topology is
recomputed.
G Use the RSTP hello-time
global configuration
command to specify the
interval (1-10) between
hello bridge protocol data
units (BPDUs).
G Use the RSTP forward-time
global configuration
command to set the
forwarding-time for the
specified RSTP instances.
The forwarding time (4-30)
determines how long each
of the listening and
learning states last before
the port begins
forwarding.
G Configure RSTP max age
parameter
I Use the RSTP cost
interface configuration
command to set the path
cost for RSTP calculations.
In the event of a loop,
RSTP considers the path
cost when selecting
an interface to place into
the forwarding state.
I Use the RSTP port-priority
interface configuration
command to configure a
port priority that is used
when two switches tie for
position as the root switch.
