6.15.3 CIST Settings
6.15.3.1 Bridge configuration
VLANs Mapped
The list of VLANs mapped to the MSTI. The VLANs must be separated with
comma and/or space. A VLAN can only be mapped to one MSTI. An unused
MSTI should just be left empty. (I.e. not having any VLANs mapped to it.)
Unmapped VLANs are mapped to the CIST. (The default bridge instance).
Bridge Priority
Control the bridge priority. Lower numeric values have better priority. The bridge
priority plus the MSTI instance number, concatenated with the 6-byte MAC
address of the switch forms a Bridge Identifier.
6.15.3.2 Port
Port No
The switch port number of the logical STP port.
Enabled STP
Control whether STP is enabled on this switch port.
Path Cost
Controls the path cost incurred by the port. The Auto setting will set 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 favour of higher path cost ports. Valid values
are in the range 1 to 200000000.
Priority
Control the port priority. This can be used to control priority of ports having
identical port cost. (See above).
