Description
This specifies the physical port to which the interface will be bound. Ports are identified by the
chassis slot 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.
This is an identification string from 1 to 79 characters (alpha and/or numeric) by which the physical
port 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.
Used when configuring static routes from the AAA interface(s) to a specific network.
IP Address: Specifies the IP address of the Foreign RADIUS authentication server the system will
communicate with to provide subscriber authentication functions.
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.
IP Address: Specifies the IP address of the foreign RADIUS accounting server that the source
context will communicate with to provide subscriber accounting functions.
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 foreign 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 foreign RADIUS
Accounting server for communications. The UDP port number can be any integer value between 1
and 65535. The default value is 1813.
Specifies the name by which the source context will be identified in the Access-Request message(s) it
sends to the RADIUS server. The name must be from 1 to 32 alpha and/or numeric characters and is
case sensitive.
Specifies the IP address of the system‟s AAA interface. A secondary address can be optionally
configured.
