If this is not done on all DHCP servers, irrespective of whether they are used with RADIUS
relay or not, it could possibly create a security vulnerability and allow an
unauthenticated client access to protected resources.
Radius Relay Object Properties
The important properties of a Radius Relay object are as follows:
• Name
A descriptive name for the object which will be used throughout the configuration.
• DHCP Server
The DHCP server that will be used to hand out IP address leases once the UE is authenticated.
• Source Interface
This is the cOS Core interface on which cOS Core will listen for AP requests. This can be any of
the following:
i. An Ethernet interface.
ii. A VLAN interface.
iii. An Interface Group.
• Client IP Filter
This specifies the source IP range that the AP belongs to. This will typically be a network
range and it is recommended it is specified as a cOS Core address book object.
• Listening IP
This is the IP address that the AP will connect to on the Source Interface. If the listening
interface is an Ethernet interface or VLAN it is optional and will default to the IP address of the
interface if not specified.
If the Source Interface is an interface group, the listening IP must be specified.
• Listening Port
This is the listening port number for the listening interface and is 1812 by default.
• Routing Table
When the UE is authenticated and it receives an IP address, a route to its IP will be
automatically added to this routing table. Usually, the default main routing table is used.
• Remote Server IP
This is the IP address of the RADIUS server that will perform UE authentication.
• Remote Server Port
This is the port number of the RADIUS server that will perform UE authentication. The default
value is 1812 which is the standard for RADIUS.
• Sending IP
