▀ Example 3: HA Using a Single Source Context and Multiple Outsourced Destination Contexts
Required Information Description
IP pool addresses An initial address and a subnet, or a starting address and an ending address, are required for each
configured pool. The pool will then consist of every possible address within the subnet , or all addresses
from the starting address to the ending address.
The pool can be configured as public, private, or static.
AAA Interface Configuration
AAA interface name This is an identification string from 1 to 79 characters (alpha and/or numeric) by which the interface will
be recognized by the system.
Multiple names are needed if multiple interfaces will be configured.
IP address and These will be assigned to the AAA interface.
subnet Multiple addresses and/or subnets are needed if multiple interfaces will be configured.
Physical port This specifies the physical port to which the interface will be bound. Ports are identified by the chassis slot
number number where the line card resides in, followed by the number of the physical connector on the line card.
For example, port 17/1 identifies connector number 1 on the card in slot 17.
A single physical port can facilitate multiple interfaces.
Physical port This is an identification string from 1 to 79 characters (alpha and/or numeric) by which the physical port
description will be recognized by the system.
Multiple descriptions are needed if multiple ports will be used.
Physical ports are used to bind logical AAA interfaces.
Gateway IP address Used when configuring static routes from the AAA interface(s) to a specific network.
RADIUS Server Configuration
RADIUS
IP Address: Specifies the IP address of the RADIUS authentication server the system will communicate
Authentication
with to provide subscriber authentication functions.
server Multiple addresses are needed if multiple RADIUS servers.
Foreign RADIUS servers are configured with in the source context. Multiple servers can be configured
and each can be assigned a priority.
Shared Secret: The shared secret is a string between 1 and 15 characters (alpha and/or numeric) that
specifies the key that is exchanged between the RADIUS authentication server and the source context.
A shared secret is needed for each configured RADIUS server.
UDP Port Number: Specifies the port used by the source context and the RADIUS authentication server
for communications. The UDP port number can be any integer value between 1 and 65535. The default
value is 1812.
RADIUS
IP Address: Specifies the IP address of the RADIUS accounting server that the source context will
Accounting server
communicate with to provide subscriber accounting functions.
(optional)
Multiple addresses are needed if multiple RADIUS servers will be configured.RADIUS accounting servers
are configured within the source context.
Multiple servers can be configured and each assigned a priority.
Shared Secret: The shared secret is a string between 1 and 15 characters (alpha and/or numeric) that
specifies the key that is exchanged between the RADIUS accounting server and the source context.
A shared secret is needed for each configured RADIUS server.
UDP Port Number: Specifies the port used by the source context and the RADIUS Accounting server for
communications. The UDP port number can be any integer value between 1 and 65535. The default value
is 1813.
