LLC2 Local Termination lets specific Token Ring ports generate and respond to
LLC2 polls with local acknowledgments, thereby preserving bandwidth and
preventing session timeouts in a Bridging application.
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.
For example, Figure 48 shows a network where running LLC2 Local Termination at
the edge point PathBuilder S24x, 26x, and 27x switches enables spoofing from one
side of the network to the other across multiple Token Rings.
