Addendum to the 32 48 and 5 224 User 's Guides

–

Forwarding — Port forwards packets, and continues learning

addresses.

•

Designated Cost — The cost for a packet to travel from this port to

the root in the current Spanning Tree configuration. The slower the

media, the higher the cost.

•

Designated Bridge — The priority and MAC address of the device

through which this port must communicate to reach the root of the

Spanning Tree.

•

Designated Port — The priority and number of the port on the

designated bridging device through which this switch must

communicate with the root of the Spanning Tree.

•

Trunk — Indicates whether the port is configured as a trunk member

The Port Settings page also contains the following fields that can be edited:

•

Priority — Defines the priority used for this port in the Spanning Tree

Protocol. If the path cost for all ports on a switch is the same, the port

with the highest priority (such as, lowest value) is 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 Protocol is detecting

network loops. Where more than one port is assigned the highest

priority, the port with lowest numeric identifier is enabled.

(Range: 0-240, in steps of 16; Default: 128.)

•

Path Cost — This parameter is used by the STP 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.

–

Range —

Ethernet: 200,000-20,000,000

Fast Ethernet: 20,000-2,000,000

Gigabit Ethernet: 2,000-200,000

–

Defaults —

Ethernet — half duplex: 2,000,000; full duplex: 1,000,000; trunk:

500,000

Fast Ethernet — half duplex: 200,000; full duplex: 100,000; trunk:

50,000

Gigabit Ethernet — full duplex: 10,000; trunk: 5,000

NOTICE: When the Path Cost Method is set to short, the maximum path cost

is 65,535.
