Radius-Server Attribute 4 - Dell N1100-ON Reference Manual

radius-server attribute 4

Use the radius-server attribute 4 command to set the network access server
(NAS) IPv4 address for the RADIUS server. The NAS-IP-Address is RADIUS
attribute number 4. Use the no version of the command to set the value to
the default.
Syntax
radius-server attribute 4 ip-address
no radius-server attribute 4
• ip-address — Specifies the IPv4 address to be used as the RADIUS
attribute 4, the NAS-IP-Address.
Default Configuration
If a RADIUS server has been configured on the switch, the default NAS-IP-
Address sent to the RADIUS server is the address of the switch or the address
of the interface over which the Access-Request is sent.
Command Mode
Global Configuration mode
User Guidelines
This command does not alter the address in the IP header in Access-Requests
transmitted to the RADIUS server. It only configures the NAS-IP-Address
attribute sent to the RADIUS server inside the RADIUS Access-Request
packet. This capability is useful when configuring multiple RADIUS clients
(switches) to simulate a single RADIUS client for scalability. The RADIUS
Acct-Session-Id may overlap if multiple switches are configured with the
same NAS-IP-Address.
The configured NAS-IP-Address need not be the same as the IPv4 source
address transmitted in the IP header. Use the radius-server source-ip
command to configure the IPv4 source address transmitted in the IP header.
Example
The following example sets the NAS IP address RADIUS attribute 4 to
192.168.10.22.
