Cables to Go TE100-S55 manual At The Port Level

AT THE PORT LEVEL

Designated Port: This is the port on each Designated Bridge that forwards data packets for the attached LAN segment.

Root Port: Each bridge has a Root Port that has the lowest Path Cost to the Root Bridge. In case there are several ports with the same Path Cost, the one with the lowest Port Identifier (Port Priority + pre-assigned Port ID) becomes the Root Port1.

Port Priority: This is a user changeable parameter for each port on the bridge. In conjunction with a pre-set port ID, this parameter determines the Root Port of a Bridge.

Path Cost: This parameter is fixed2 and will not be shown. The 100Mb segments will have auto-assigned Path Cost of 10, while the 10Mb segments will have auto-assigned Path Cost of 100.

1In a bridge, a port is Blocked, if it is not a Root or a Designated Port.

2This is a changeable parameter, based on the STA specification. However, it is fixed by the TE100-S55 implementation.
