Modifying PPP Parameters for Backup Lines
Using the BCC, you can modify several PPP line parameters to customize how
PPP operates across a backup line. The next sections describe how to set these
parameters.
To set the equivalent Site Manager parameters, see Configuring PPP Services.
Setting a Time Limit for Convergence
Convergence occurs when the peers have negotiated all the parameters needed to
establish a dial connection. You can limit the amount of time that PPP attempts to
negotiate a dial PPP interface by setting the convergence-timer parameter.
The convergence timer specifies the maximum number of seconds allowed for the
completed negotiations. It limits the LCP negotiations and requires at least one
NCP to negotiate within the configured amount of time. The default value is 300
seconds. If the timer expires before the negotiation completes, the connection is
cleared.
The convergence timer allots the configured number of seconds for the link
control protocol (LCP) to negotiate and allots the same period for one network
control protocol (NCP) to complete negotiations.
To set the convergence timer, navigate to the dial prompt and enter:
convergence-timer
<
integer
>
integer can be a value from 1 to 5000 seconds.
For example:
dial/bri/1/1# convergence-timer 350
