Bridging

PathBuilder S200 series switches support mixed LAN bridging, meaning you can 
configure an Ethernet interface in the same node. Refer to the “Mixed LAN 
Bridging” section on page 8 for more details.

PathBuilder S200 series switches can use the Translational Bridging feature to 
bridge traffic between Ethernet Networks. Translational Bridging provides a 
PathBuilder S200 series switch with the capability to bridge non-routable protocols. 
For information about enabling and configuring Translational Bridging, refer to the 
“Configuring Translational Bridging” section on page 37.

As mentioned earlier, PathBuilder S200 series switches are not intended for use in 
local bridging applications where one LAN is connected directly to another LAN. It 
is not recommended you use PathBuilder S200 series switches to perform local 
bridging.

Transparent Bridging (TB) is the method used by PathBuilder S200 series switches 
to bridge Ethernet LAN traffic from one Ethernet LAN to another one across a 
WAN. 

Refer to Transparent Bridging for Ethernet LANs on page 48 for more details on 
these bridging operations.

The PathBuilder S200 series switch family supports many types of protocols for 
bridging operations. Some of the supported protocols include:

• Async

• SDLC

• Bisync

• Transparent Polled Async

• HDLC

• X.25

• Frame Relay

• Burroughs Poll Select

• NCR Bisync
