| Specifies the port cost. It can be set between | |
Cost | the greater the probability the port will be chosen as the designated port | |
(chosen to forward packets). The default value for the 10/100 ports is 19, | ||

| and for the 100/1000 ports it is 4. | |
|
| |
| Specifies the port priority. It can be set between | |
| The lower the priority, the greater the probability the port will be chosen as | |
Priority | the root port. If two ports have the same priority, the port with the lowest port | |
| number is selected. For example, STP chooses port 1 over port 5 if they | |
| both have the same priority. | |
|
| |
State | Enables or disables STP on the specified port or range of ports. | |

The Status field displays whether the port is Disabled or Forwarding. The STP Name field displays the assigned STP group name for the port.
Forwarding
Forwarding reduces traffic congestion on the network because packets are transmitted only to the destination port rather than to all ports. The switch maintains a number of static forwarding tables which you can manually configure for MAC, IP, and ARP forwarding.
This section explains how to configure
•MAC address aging
•MAC forwarding (unicast MAC address, multicast MAC address, and storm control)
•IP forwarding (static and default routes, static ARP)
To configure MAC address aging
A very long MAC address aging time can result in
1.In the left panel, select Forwarding.
2.In the top panel under MAC Forwarding, select MAC Address Aging Time.
3.In the MAC Address Aging Time field, specify the length of time a learned MAC address can remain in the forwarding table without being accessed (that is, how long a learned MAC Address is allowed to remain idle). The aging time can be set to any value between 300— 1,000,000 seconds. The default is 300 seconds (5 minutes).
4.Click Apply.
To configure unicast MAC address forwarding
1. In the left panel, click Forwarding.
1. In the top panel under MAC Forwarding, click Unicast MAC Address Settings.
