MST Port Settings
This page displays the current MSTI configuration
information for the Switch. From here you can update
the port configuration for an MSTI ID. If a loop occurs,
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
for forwarding first. In instances where the priority
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
priority is: 32768. The valid range is
from 0–61440.
Internal Path Cost Conf: The Internal Path Cost setting allows
you to specify the relative cost of
sending spanning tree traffic through
the interface to adjacent bridges
within a spanning tree region.
Internal Path Cost Oper: Displays the operation cost of the
path from this bridge to the Root
Bridge.
Regional Root Bridge: This is the bridge identifier of the
CST Regional Root. It is made up us-
ing the bridge priority and the base
MAC address of the bridge.
