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 L128/L128T 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 pro-
tocol. 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 L128/L128T is mainly used for allowing a
network to have multiple virtual network connections to many destinations
using the single ISDN link. The Express L128/L128T can periodically obtain
routing information from various locations and retain this in the routing ta-
bles, thereby permitting the LAN connection to be aware of the networks at
this location. Probe helps keep route tables updated. When a service or net-
work connection is required, the Express L128/L128T can demand dial that lo-
cation. This can be beneficial for remote IPX workstations that cannot boot up
properly without knowing the IPX services that would be in the Express L128/
L128T’s SAP table.
Probe/Active
Write security: 3; Read security: 5
When set to Yes, the Express L128/L128T 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 L128/L128T waits between probes. The value is
in minutes and ranges from 1 to 240. The default is 15 minutes.
