Description
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 configured within the source context and are used to bind logical DHCP interfaces.
This is an identification string between 1 and 63 characters (alpha and/or numeric) by which the DHCP
service will be recognized by the system.
Multiple names are needed if multiple GGSN services will be used.
The IP address of each DHCP server that the system is to communicate with must be configured
.Multiple servers can be configured. If multiple servers are configured, each can be assigned a priority
from 1 to 1000. The default priority is 1.
Specifies the minimum and maximum allowable lease times that are accepted in responses from DHCP
servers.
Minimum Lease Time: Measured in seconds and can be configured to any integer value from
600 to 3600. The default is 600 seconds.
Maximum Lease Time: Measured in seconds and can be configured to any integer value from
10800 to 4294967295. The default is 86400 seconds.
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.
These will be assigned to the AAA 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 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 RADIUS authentication server the system will
communicate with to provide subscriber authentication functions.
Multiple addresses are needed if multiple RADIUS servers will be configured. If multiple servers are
configured, 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.
