Termination
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.
LT Example
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.
