User’s Manual of WGSD-1022/WGSD-8000

 

 

 

 

 

 

• Interface

Indicates the port or LAG on which STP is enabled

• STP

which indicates if STP is enabled on the port

• Port Fast

Indicates if Fast Link is enabled on the port. If Fast Link mode is enabled for a port,

 

the Port State is automatically placed in the Forwarding state when the port link is

 

up. Fast Link optimizes the STP protocol convergence. STP convergence can take

 

30-60 seconds in large networks.

• Port State

Displays the current STP state of a port. If enabled, the port state determines what

 

forwarding action is taken on traffic. Possible port states are:

 

• Disabled, indicates that STP is currently disabled on the port. The port

 

forwards traffic while learning MAC addresses.

 

• Blocking, where indicates that the port is currently blocked and cannot

 

forward traffic or learn MAC addresses. Blocking is displayed when Classic

 

STP is enabled.

 

• Listening, where indicates that the port is in Listening mode. The port cannot

 

forward traffic nor can it learn MAC addresses.

 

• Learning, where indicates that the port is in whose mode. The port cannot

 

forward traffic, however it can learn new MAC addresses.

 

• 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 Indicates the bridge priority and the MAC Address of the designated bridge.

ID

•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.
