cdma pdsn a10 init-ppp-after-airlink-start airlink-start-timeout
cdma pdsn a10 init-ppp-after-airlink-start airlink-start-timeout
To configure the PDSN so that Point-to-Point Protocol (PPP) negotiation with an MN starts only after
the traffic channel is assigned, (in other words, after a Registration Request with airlink-start is
received), use the cdma pdsn a10 init-ppp-after-airlink-start command in global configuration mode.
Use the no form of this command to revert to the default behavior.

Syntax Description
Defaults
This CLI is not enabled, therefore, the PDSN initiates PPP negotiation immediately after a Registration
Reply is sent to the initial Registration.Request.
Reply is sent to the initial Registration.Request.
When enabled, the default timeout interval is 10 seconds.

Usage Guidelines
The PDSN initiates PPP negotiation immediately after a Registration Reply is sent to the initial
Registration Request, but the calls (for which the PPP negotiation has started before the traffic channel
is assigned to MN) have failed.
Registration Request, but the calls (for which the PPP negotiation has started before the traffic channel
is assigned to MN) have failed.
When this command is enabled, the PPP negotiation with the MN starts only after the traffic channel is
assigned—after a Registration Request with airlink-start is received. If the airlink start is not received at
all, the session is torn down when timeout occurs.By default, this timeout interval is 10 seconds, or can
be configured through the CLI.

The session is not torn down immediately after the timeout, so, in order to minimize the impact on the
performance, there is just one timer started to keep track of all the sessions waiting for airlink-start to
start PPP.
performance, there is just one timer started to keep track of all the sessions waiting for airlink-start to
start PPP.
For example, with a default of 10 seconds, if the timer expires at t1 and a new call comes at t2(t2 >t1),
the next run of the timer is at t1+10. It is likely that the uptime for the call is not more than 10 seconds
since t2 > t1. So the call is checked at the next run (t1+10+10). Thus, the variation is between 1 and 10.

Examples
The following example shows how to enable the cdma pdsn a10 init-ppp-after-airlink-start
airlink-start-timeout command:
airlink-start-timeout command:
Router# cdma pdsn a10 init-ppp-after-airlink-start airlink-start-timeout 20
1-120
Sets the timeout interval before the session is torn down.
