Modifying PPP Dial Interfaces in a Pool
Using the BCC, you can modify several PPP parameters to customize how PPP
lines operate as dial interfaces. You can modify these parameters for both modem
and ISDN lines. 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
is a value from 1 to 5000 seconds.
For example:
dial/bri/1/1#
convergence-timer 350
