Express 4110/4120 User Manual

61200176L3-1

The Probe feature on the Express 4110/4120 is mainly used for allowing a 
network to have multiple virtual network connections to many destina-
tions using the single ISDN link.  The Express 4110/4120 can periodically 
obtain routing information from various locations and retain this in the 
routing tables, thereby permitting the LAN connection to be aware of the 
networks at this location. Probe helps keep route tables updated. When a 
service or network connection is required, the Express 4110/4120 can 
demand dial that location. This can be beneficial for remote IPX worksta-
tions that cannot boot up properly without knowing the IPX services that 
would be in the Express 4110/4120’s SAP table.

Write security: 3; Read security: 5

This is the time the Express 4110/4120 stays connected during a probe.  
Normally route and service tables are exchanged immediately after con-
nection.  However, some routers could wait until their regular RIP or SAP 
time period has been reached before they advertise their routes or services 
to the Express 4110/4120.  The value is in seconds and ranges from 5 to 
180.  The default is 5 seconds and assumes that a routing update is 
received upon connection.
