How to Configure
Dual Ethernet LAN
Follow these steps to configure a node for Multiple Ethernet LAN.
Step Action Result/Description
1 Make a local CTP connection to a
PathBuilder S24x, 26x, and 27x
switch.
The CTP is physically connected to
the device you are configuring.
2 Select Configure -> Port from the
CTP Main menu.
The Port record appears.
3 Configure the Port record as you
normally do for an Ethernet LAN
connection.
Two new parameters, Bridge Link
Number and Router Interface,
appear in the record.
4 At the Bridge Link Number:
parameter, type in a number 1-4 to
identify the bridge link, and press
Return.

The default value for this
parameter is 1.
This matches this port configuration
to a specific bridge link number
within the bridging configuration. If
the bridge link you select is already
used, a warning message appears,
but your input is retained in the
CMEM.
5 At the Router Interface Number:
parameter, type in a number 1-4 to
identity the router interface.
Note

interface number you select is
already used, a warning message
appears, but your input is retained
in the CMEM.
