Autolearn For Local Termination - 3Com PathBuilder S200 Series Owner's Manual

Autolearn for Local Termination

What Is It?
Local Termination Autolearn reduces the amount of configuration you need to do by
letting you spoof remote sessions without configuring a MAC address and a Service
Access Point (SAP) for each station running a session to the host Front End
Processor (FEP).
Since Local Termination supports up to 256 sessions for the PathBuilder S24x, 26x,
and 27x switch, Local Termination Autolearn can save you considerable time during
the configuration process.
Local Termination Autolearn is a default feature with PathBuilder S200 series
switches operating software meaning it requires no special configuration, other than
configuring the remote host MAC address in the PathBuilder S200 series switch
Local Termination (LT) Station tables.
It does not interfere with previously configured Local Termination spoofing
sessions.
Example
Figure 8 shows how a PathBuilder S200 series switch automatically learns the
address of PCs connected to the local bridge so you can pass data traffic to the host
without configuring entries in the Local Termination Station table for each PC
session.

addresses.
