information for the Switch. From here you can update
theportcongurationforanMSTIID.Ifaloopoccurs,
the MSTP function will use the port priority to select
an interface to put into the forwarding state. Set a
higher priority value for ports you wish to be selected
forforwardingrst.Ininstanceswherethepriority
value is identical, the MSTP function will implement the
lowest MAC address into the forwarding state and other
interfaces will be blocked. Note that a lower priority
values mean higher priorities for forwarding packets.
MST ID:
Displays the ID of the MST group
that is created. A maximum of 15
groups can be set for the Switch.
Port:
Displays port or trunked port ID.
Priority:
Select the bridge priority value for
the MST. When Switches or bridges
are running STP, each is assigned a
priority. After exchanging BPDUs,
the Switch with the lowest priority
value becomes the root bridge. The
bridge priority is a multiple of 4096.
If you specify a priority that is not
a multiple of 4096, the priority is
automatically set to the next lowest
priority that is a multiple of 4096.
For example, if you set the priority
to any value from 0 through 4095,
the priority is set to 0. The default
priorityis:32768.Thevalidrangeis
from 0–61440.
