PathBuilder S200 series switch support includes LLC2 Local Termination for your
Bridging operations when passing SNA/SDLC data traffic. LLC2 Local Termination
lets specific Token Ring ports generate and respond to LLC2 polls with local
acknowledgments, thereby preserving bandwidth and preventing session timeouts.
Local Termination, also referred to as "spoofing," provides an efficient means for
carrying out an LLC2 session between two SNA end stations attached to separate
Token Ring LANs connected by a Wide Area Network (WAN).
Additionally, Local Termination provides detailed statistics on LLC2 sessions.
Figure 7 shows a network where running LLC2 Local Termination at the edge point
PathBuilder S200 series switches enables spoofing from one side of the network to
the other across multiple Token Rings.
