Description
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 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 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.
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.
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.
PDN interfaces are configured in the destination context.
These will be assigned to the PDN interface.
Multiple addresses and/or subnets are needed if multiple interfaces will be configured.
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 will be needed if multiple ports will be used.
Physical ports are configured within the destination context and are used to bind logical PDN
interfaces.
Used when configuring static routes from the PDN interface(s) to a specific network.
This is an identification string from 1 to 31 characters (alpha and/or numeric) by which the physical
port will be recognized by the system.
Multiple descriptions will be needed if multiple ports will be used.
