Spanning Tree | MSTI Ports
This page allows you to inspect the current STP MSTI port configurations, and possibly change them as well.
An MSTI port is a virtual port, which is instantiated
separately for each active CIST (physical) port for each MSTI
instance configured on and applicable to the port. The MSTI
instance must be selected before displaying actual MSTI port
configuration options. This page contains MSTI port settings
for physical and aggregated ports.
Click the Get button to retrieve settings for a specific MSTI.
Item Configuration | Spanning Tree | MSTI Ports
Port
The MP1204-XT port number of the corresponding STP CIST (and
MSTI) port.
Path Cost
Controls the path cost incurred by the port. The
Auto
setting sets the
path cost as appropriate by the physical link speed, using the 802.1D
recommended values. Using the
Specific
setting, a user-defined value
can be entered. The path cost is used when establishing the active
topology of the network. Lower path cost ports are chosen as
forwarding ports in favor of higher path cost ports. Valid values are
in the range 1 to 200000000.
Priority
Controls the port priority. This can be used to control priority of ports
having identical port cost. (See above).
