6 To set the LAN port cost, type then press . At the prompt,
enter a value for the LAN port cost between 0 and 65535 (the default
value is 100):
Enter New LAN Port Cost : 1000
This represents the cost for a packet to travel to the root in the current
Spanning Tree configuration. This value is 0 if your bridge is the root
device. The lower the transmission rate is for the LAN (10 or 100 Mbps),
the higher you should configure its cost. When ports have the same path
cost, port priority is considered.
7 To set the Line port priority, type then press . At the prompt,
enter a value for the Line port priority between 0 and 255 (the default
value is 128):
Enter New Line Port Priority : 65
Port priorities are set relative to other ports on the same bridge. When the
ports simultaneously request access to the network, this priority level
determines the order in which the ports get access. The LAN is the other
port on this bridge.
8 To set the Line port cost, type then press . At the prompt, enter
a value for the Line port cost between 0 and 65535 and 648 is the default
value.
Enter New Line Port Cost : 1250
This represents the cost for a packet to travel to the root in the current
Spanning Tree configuration. This value is 0 if your bridge is the root
device. The lower the transmission rate is for the Line (HDSL rate from
64 kbps to 4.608 Mbps), the higher is its cost. When ports have the same
path cost, port priority is considered.
9 Type to return to the Bridge Configuration screen ( page 3-32 ) from
which you can configure other bridge parameters. (Typing will return
you to the Main Menu.)
10 If you are changing only Spanning Tree Protocol parameters, go to
“Saving the Bridge Configuration” on page 40 to save your changes.
