Use the MIST Ports Configuration page to configure STA attributes for
interfaces in a specific MSTI, including path cost, and port priority. You may
use a different priority or path cost for ports of the same media type to
indicate the preferred path. (References to “ports” in this section means
“interfaces,” which includes both ports and trunks.)

These parameters are displayed:
◆
Port – Port identifier.
This field is not applicable to static trunks or dynamic trunks created
through LACP. Also, note that only one set of interface configuration
settings can be applied to all trunks.
◆
Path Cost – This parameter is used by the STA to determine the best
path between devices. Therefore, lower values should be assigned to
ports attached to faster media, and higher values assigned to ports
with slower media. (Path cost takes precedence over port priority.)
By default, the system automatically detects the speed and duplex
mode used on each port, and configures the path cost according to the
values shown in Table 9 , Table 10 and Table 11 .
