corporate intranet.
AAA Interfaces
Using the LAN ports located on the Switch Processor I/O (SPIO) and Ethernet line cards, these interfaces carry AAA
messages to and from RADIUS accounting and authentication servers. The SPIO supports RADIUS-capable
management interfaces using either copper or fiber Ethernet connectivity through two auto-sensing 10/100/1000 Mbps
Ethernet interfaces or two SFP optical gigabit Ethernet interfaces. User-based RADIUS messaging is transported using
the Ethernet line cards.
While most carriers will configure separate AAA interfaces to allow for out-of-band RADIUS messaging for system
administrative users and other operations personnel, it is possible to use a single AAA interface hosted on the Ethernet
line cards to support a single RADIUS server that supports both management users and network users.

Important:
Subscriber AAA interfaces should always be configured using Ethernet line card interfaces for the
highest performance. The out-of-band local context should not be used for service subscriber AAA functions.
Co-Located Deployments
An advantage of the system is its ability to support both high-density PDSN/FA and HA configurations within the same
chassis. The economies of scale presented in this configuration example provide for both improved session handling and
reduced cost in deploying a CDMA2000 data network.
The following figure depicts a sample co-located deployment.
