stations, avoiding and eliminating loops.

#Notice:

• Max Age -. The value lies between 6 and 40, with the value being less than or equal to "(2 *

Bridge Forward Delay) - 1" and greater than or equal to "2 * ( Bridge Hello Time +1)". The

default value is 20.

• Hello Time - The value being less than or equal to "(Bridge Max Age / 2) - 1". The default hello

time value is 2.

• Forward Delay- Bridge Forward Delay must be greater or equal to "(Bridge Max Age / 2) + 1".

The time range is from 4 seconds to 30 seconds. The default value is 15.

4.6.2 RSTP Port Configuration

The RSTP Port Configuration page contains fields for assigning RSTP properties to individual ports. The screen in Figure

4-25 appears.

Figure 4-25 RSTP Port Configuration

The page includes the following fields:

• Port

Indicate port 1 to port 24.

• Edge

Indicates whether the port is enabled as an edge port.

Edge port cannot create loops, but it loses edge port status if a topology change

creates a potential for a loop. An edge port normally should not receive BPDU

packets. If a BPDU packet is received it automatically loses edge port status.

• Path Cost

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:
