Counter for IPCP term request

The PDSN has a metric for tracking IPCP Term Requests sent by the Mobile. This metric distinguishes
the difference between the following two cases.

Case a

MN will send IPCP TermReq to PDSN

PDSN will send IPCP TermAck to MN

MN will inform PCF to send A11 De-registration

Case b

During IPCP negotiation phase, PCF send A11 De-registration for some PCF reason.

As per the existing behavior, PDSN will increment “A10 release during IPCP nego by pcf" counter. So
new counters will be added as “With IPCP Term Req” under “A10 release during ipcp nego” counter,
which will indicate how many a10 releases happened due to IPCP term request transmission between
MN and PDSN.

Similarly, new counters will be added under “LCP Term req during IPCP nego” counter to tell how many
LCP disconnect happened due to IPCP term request transmission between MN and PDSN.

The following example snippet shows the output for the show cdma pdsn statistics ppp command:

IPCP Stage

Failure Reasons Options 0, MaxRetry 0, Unknown 0

Options failure reason MN Rejected IP Address 0

LCP Term Req during IPCP nego sent 0, rcvd 0

With IPCP Term Req sent 0, rcvd 0

A10 release during IPCP nego by PDSN 0, by PCF 0

With IPCP Term Req sent by PDSN 0, by PCF 0

With the implementation of this new counter, we can easily differentiate the above mentioned cases:
