PDSN on MWAM

The MWAM supports the feature set of PDSN Release 2.0, and functionality remains the same as on the

Cisco 7200 platforms. The significant difference between the Cisco PDSN on the Cisco 7200 router and

on the MWAM is that a Cisco Catalyst 6500 or Cisco 7600 chassis will support a maximum of 6

application modules. Each application module supports 5 IOS images, each with access to 512

Megabytes of RAM. Up to five of these images can function as a PDSN.

Additionally, instances of the cluster controller functionality will be configured as required. One active

and one standby controller are required for a cluster of 48 PDSN instances or less. Each PDSN image

supports 20,000 sessions. For every 10 PDSNs configured in the chassis, one active and one standby

controller is required. Internal to the chassis, the PDSN images are configured on the same VLAN in

order to support the Controller-Member architecture (although the architecture itself does not require

this). Load balancing external to the chassis is determined by the physical proximity of the chassis and

the network architecture. It is possible that you require both a VLAN approach, and a more traditional

routed approach.
