PARAMETERS
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.
◆ STP Enabled – Sets the interface to enable STA, disable STA, or disable STA with BPDU
transparency. (Default: Enabled) BPDU transparency is commonly used to support BPDU
tunneling, passing BPDUs across a service provider’s network without any changes, thereby
combining remote network segments into a single spanning tree. As implemented on this
switch, BPDU ransparency allows a port which is not participating in the spanning tree (such
as an uplink port to the service provider’s network) to forward BPDU packets to other ports
instead of discarding these packets or attempting to process them.
◆ 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
