Table 12-2 lists ways to modify your bandwidth-on-demand configuration.
Changing the Authentication Protocol
CHAP is the default authentication protocol. To select PAP, you must specify PAP
for the Local Authentication Protocol parameter. For instructions, see Configuring
PPP Services.
Monitoring Congestion on the Bandwidth or Demand Circuit
To relieve congestion across the leased bandwidth or demand circuit, a router on
one side of the connection must monitor the traffic level on the circuit.
The Bandwidth Mode parameter in the Circuit Options window specifies which
router monitors congestion. The default for this parameter is Non-Monitor.
Changing the value to Monitor makes your router the congestion monitor. You can
then modify the congestion monitor parameters, which determine when the router
activates additional lines to relieve congestion.
Although Site Manager provides default values for the monitor parameters, edit
them for your network applications. If the network is critical to your operations
and you want to ensure expedient data transmission, customize your threshold
values so that even with moderate congestion, the router activates additional lines.
Remember to account for data compression, which will also relieve congestion
over a line. Also, the cost of additional lines may determine how often you want
the router to activate the lines.
