Chapter 3 - Configuring the REX2
6To set the LAN port cost, type 7 then press ENTER . 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.
7To set the Line port priority, type 8 then press ENTER . 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.
8To set the Line port cost, type 9 then press ENTER . 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.
