PLANET WGSD-1022 - Manual (Page 53)

• Forwarding, the port that can forward traffic and learn new MAC addresses.
• Speed
Indicates the speed at which the port is operating
• Path Cost
Indicates the port contribution to the root path cost. The path cost is adjusted to a
higher or lower value, and is used to forward traffic when a path being rerouted.
Value Rage : 1-20000000
Default Path Cost - The default path cost of the port is automatically set by the
port speed and the default path cost method. The default values for path costs
are:
- Ethernet - 2000000
- Fast Ethernet - 200000
- Gigabit Ethernet - 20000
• Default Path
Cost
When selected the default path cost is implemented
• Priority
Indicates priority value of the port. The priority value influences the port choice
when a bridge has two ports connected in a loop. The priority value is between 0
-240. The priority value is provided in increments of 16.
• Designated
Bridge ID
Indicates the bridge priority and the MAC Address of the designated bridge.
• Designated Port
ID
Indicates the selected port’s priority and interface.
• Designated Cost Where indicates the cost of the port participating in the STP topology. Ports with a
lower cost are less likely to be blocked if STP detects loops.
• Forward
Transitions
This indicates the number of times the port has changed from the Blocking state
to Forwarding state.
