CIST Ports
This page allows the user to inspect the current STP CIST port configurations, and possibly
change them as well.
This page contains settings for physical and aggregated ports.
Port
The switch port number of the logical STP port.
STP Enabled
Controls 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.
