ONFIGURING THE
• 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.)
• Priority – Defines the priority used for this port in the Spanning Tree
Algorithm. If the path cost for all ports on a switch is 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 the lowest numeric identifier will be
enabled.
• Designated root – The priority and MAC address of the device in the
Spanning Tree that this switch has accepted as the root device.
• Fast forwarding – This field provides the same information as Admin
Edge port, and is only included for backward compatibility with earlier
products.
• Admin Link Type – The link type attached to this interface.
• Point-to-Point – A connection to exactly one other bridge.
• Shared – A connection to two or more bridges.
• Auto – The switch automatically determines if the interface is attached
to a point-to-point link or to shared media.
• Admin Edge Port – You can enable this option if an interface is
attached to a LAN segment that is at the end of a bridged LAN or to
an end node. Since end nodes cannot cause forwarding loops, they can
pass directly through to the spanning tree forwarding state. Specifying
Edge Ports provides quicker convergence for devices such as
workstations or servers, retains the current forwarding database to
reduce the amount of frame flooding required to rebuild address tables
