Features From Previous Releases
This section explains the features that were introduced in releases earlier than Cisco PDSN Release 5.5.
Simple IP Client IP Accounting Support
Cisco PDSN provides support for simple IP customers to connect to the L2TP Network Server (LNS) on
their home network for IP address assignment. The Cisco PDSN watches for the IPCP configuration
acknowledgement returning from the LNS during PPP negotiation between the MS and the LNS. It then
extracts the IP address and uses this address, instead of 0.0.0.0 for all subsequent AAA packets.

Note
Simple IP accounting does not support IPv6 addresses that are assigned by the LNS.
A new CLI command, cdma pdsn accounting vpdn address [include renegotiation], is introduced in
Cisco PDSN Release 5.1. In earlier releases of Cisco PDSN, the accounting-start (with MN IP using all
zeroes) is sent out as soon as an L2TP tunnel is established. When you enable the cdma pdsn accounting
vpdn address [include renegotiation] command, the accounting-start is delayed till Cisco PDSN gets
a valid IP address for the mobile. If the call goes down before the IP address is negotiated, no accounting
message is sent.

Note
When you enable the CLI command with an extension (including renegotiation), all the packets for
VPDN are snooped, thus impacting the performance of Cisco PDSN. If the LNS does not change the IP
address during renegotiation, you can remove the extension of the CLI (including renegotiation). By so
doing, after the mobile IP address is received, snooping is stopped.

SNMP New MIB Objects for Per PCF
The Cisco PDSN requires SNMP management support for per-PCF PPP statistics. The MIB object
defines the manageable objects. Table 8 and 9 describe the new MIB objects per PCF and the VPDN MIB
objects that are introduced in Cisco PDSN Release 5.1, respectively.
