Connection List/Bridge
The Bridge menu contains the parameters needed for exchanging bridged
packets with the PPP peer.
Bridge/Mode
Write security: 3; Read security: 5
When set to On (def), the Express XL/XLT will attempt to negotiate PPP BCP
with the PPP peer. Bridging can be used even in route mode only if the PPP
peer cannot support certain PPP protocols for that particular routing protocol.
See Bridge/WAN IP Bridge on page 50 and Bridge/WAN IPX Bridge on page 51
for further details.
Connection List/Probe
The Probe feature on the Express XL/XLT is mainly used for allowing a net-
work to have multiple virtual network connections to many destinations using
the single ISDN link. The Express XL/XLT can periodically obtain routing in-
formation 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 XL/XLT can demand dial that location. This can be
beneficial for remote IPX workstations that cannot boot up properly without
knowing the IPX services that would be in the Express XL/XLT’s SAP table.
Probe/Active
Write security: 3; Read security: 5
When set to Yes, the Express XL/XLT will periodically dial this profiles dial-
out number to get routing and service table updates. The default is No.
Probe/Interval
Write security: 3; Read security: 5
This is the time the Express XL/XLT waits between probes. The value is in
minutes and ranges from 1 to 240. The default is 15 minutes.
