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 .
◆
Priority – Defines the priority used for this port in the Spanning Tree
Algorithm. If the path cost for all ports on a switch are the same, the
port with the highest priority (i.e., lowest value) will be configured as
an active link in the Spanning Tree. This makes a port with higher
priority less likely to be blocked if the Spanning Tree Algorithm is
detecting network loops. Where more than one port is assigned the
highest priority, the port with lowest numeric identifier will be enabled.
