LAN Port/Priority

Write security: 2; Read security: 5
The priority adjusts the relative priority of the Ethernet port
among the multiple bridge ports. The range is 0 to 255 with a
default of 128.

Spanning Tree/WAN Port 0

The WAN port 0 is considered to be the first PPP BCP connection that
occurs over the ISDN link. It can be a single B channel or two B chan-
nels running PPP Multilink.

WAN Port 0/Active

Write security: 2; Read security: 5
The WAN 0 port can be disabled when set to No. In this mode,
no bridge traffic will be forwarded in or out. Setting to Yes (def)
allows the port to participate in the spanning tree topology.

WAN Port 0/Path Cost

Write security: 2; Read security: 5
This is the cost of using the WAN port 0 in the total cost of the
path. The range is from 1 to 65535 with a default of 15625 (for 64
kbits/second). Note that when running over two B channels
using PPP Multilink, the range does not adjust itself. If it is
known that the only WAN port will be WAN port 0 over two B-
channels, then the path cost for this port should be changed to
7812 (128 Kbits/second).

WAN Port 0/Priority

Write security: 2; Read security: 5
The priority adjusts the relative priority of the WAN port 0
among the multiple bridge ports. The range is 0 to 255 with a
default of 128.

Spanning Tree/WAN Port 1

WAN port 1 is considered to be the second B channel PPP BCP con-
nection made. This port is only used when the first B channel (WAN
Port 0) is going to an entirely different bridge.
