Configuring Peer-to-Peer PDSN Selection
A group of Cisco PDSNs can be configured to exchange session information with one another when
needed. When a session request is received by the PDSN, it not only checks its own session list for the
existence of a session, it also checks the lists of the PDSNs within its group. If a session exists in the
group, the Mobile IP registration message for the session is rejected, and an alternate PDSN is
recommended. The BSC/PCF can then establish session with the recommended PDSN.
To configure PDSN selection and PDSN load balancing, use the following commands in global
configuration mode:
Enabling Network Management
To enable SNMP network management for the PDSN, use the following commands in global
configuration mode:
Command Purpose
Router(config)# cdma pdsn secure cluster default spi
spi_index [key ascii | hex value]

in a cluster.
Router(config)# cdma pdsn cluster member controller
ipaddr
Configures the PDSN to operate as a cluster member.
Router(config)# cdma pdsn cluster member interface
interface name
Configures the PDSN to operate as a cluster member.
Command Purpose
Router(config)# cdma pdsn selection interface
interface_name

Router(config)# cdma pdsn selection load-balancing
[threshold val [alternate]]

The Alternate option alternately suggests two other PDSNs
with the least load.
Router(config)# cdma pdsn selection keepalive value
Specifies the length of time to track a PDSN that is not
responding.
Router(config)# cdma pdsn secure cluster default spi
{spi_val | [inbound inspi_val outbound outspi_val]}
key {ascii|hex} string
Specifies the default mobility security associations for all
PDSNs in a cluster, as well as inbound and outbound spi
values.
1. You must issue the cdma pdsn selection session-table-size command before you issue the cdma pdsn selection load-balancing command.
Command Purpose
Router(config)# snmp-server community string [ro | rw]
Specifies the community access string to permit
access to the SNMP protocol.
Router(config)# snmp-server enable traps cdma
Enables network management traps for CDMA.
Router(config)# snmp-server host host-addr traps version {1 |
