LAN Port/Path Cost
Write security: 2; Read security: 5
This is the cost of using the Ethernet port in the total cost of the path. The
range is from 1 to 65535 with a default of 100 (for 10 Mbits/second).
LAN Port/Priority
Write security: 2; Read security: 5
The priority adjusts the relative priority of the Ethernet port among the multi-
ple 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 channels 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 traf-
fic will be forwarded in or out. Setting to Yes (def) allows the port to partici-
pate 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 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 multi-
ple 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 connection
made. This port is only used when the first B channel (WAN Port 0) is going
to an entirely different bridge.
