Chapter 40 Configuration Mode Commands

where
An example using
spanning-tree
command is shown next.
• Enable STP on the Switch.
• Set the bridge priority of the Switch to 0.
• Set the Hello Time to 4, Maximum Age to 20 and Forward Delay to 15 on the Switch.
spanning-tree
=
Enables STP on the Switch.
mrstp <treeIndex>
Enables a specific tree configuration.
priority <0-61440>
=
Specifies the bridge priority for the Switch. The lower the
numeric value you assign, the higher the priority for this bridge.
Bridge priority is used in determining the root switch, root port
and designated port. The switch with the highest priority
(lowest numeric value) becomes the STP root switch. If all
switches have the same priority, the switch with the lowest
MAC address will then become the root switch.
Bridge Priority determines the root bridge, which in turn
determines Hello Time, Max Age and Forwarding Delay.
hello-time <1-10>
=
Specifies the time interval in seconds between BPDU (Bridge
Protocol Data Units) configuration message generations by the
root switch.
maximum-age <6-40>
=
Specifies the maximum time (in seconds) a switch can wait
without receiving a BPDU before attempting to reconfigure. All
switch ports (except for designated ports) should receive
BPDUs at regular intervals. Any port that ages out STP
information (provided in the last BPDU) becomes the
designated port for the attached LAN. If it is a root port, a new
root port is selected from among the Switch ports attached to
the network.
forward-delay <4-
30>
=
Specifies the maximum time (in seconds) the Switch will wait
before changing states. This delay is required because every
switch must receive information about topology changes before
it starts to forward frames. In addition, each port needs time to
listen for conflicting information that would make it return to a
blocking state; otherwise, temporary data loops might result.
<port-list> path-
cost <1-65535>
=
Enables STP on the specified ports.
Specifies the cost of transmitting a frame on to a LAN through
that port. It is assigned according to the speed of the bridge.
<port-list>
priority <0-255>
=
Specifies the priority for each port.
Priority decides which port should be disabled when more than
one port forms a loop in a switch. Ports with a higher priority
numeric value are disabled first.
<port-list>
treeIndex <1-4>
=
Specifies which STP configuration these ports will participate
in. (
mrstp
command only).
