Setting Up Wan Operation For Bridging - 3Com PathBuilder S200 Series Owner's Manual

Setting Up WAN Operation for Bridging

Introduction
With the 3Com Bridging Protocol option, you can use PathBuilder S200 series
switches to connect remote LANs across a Wide Area Network (WAN), as shown in
Figure 13.

Critical Parameters
Before you can use a PathBuilder S200 series switch as a bridge to connect LANs
for WAN Operation
over a WAN, you must configure the following two parameters in the Node record
for the bridge node. In most cases, use default values:
You also need to configure the LAN Connection Table. Entries in this table are for
the WAN Adapter and specify connections going across a wide area network, such as
X.25, Frame Relay, or other proprietary protocols.
Codex Proprietary
The Protocol Identifier (ID) is placed on the Call User Data field of the Call Request
Protocol ID
packet. This packet is generated by the Autocall used to establish a circuit for a
bridge link. If the bridge link is not configured to initiate an autocall, then this
configured value is matched with that found in an Incoming Call packet to determine
if the call should be established.
To define the Codex Proprietary Protocol ID, select a value within the designated
range. Normally you would not configure a value different from the default value.
The only reason to use a different value is if the default value conflicts with one
already in use.
It is recommended that the Protocol ID value in all network nodes be the same.
