nas-ip (RADIUS scheme view)

Use nas-ip to specify a source IP address for outgoing RADIUS packets.
Use undo nas-ip to delete a source IP address for outgoing RADIUS packets.
Syntax
nas-ip { ipv4-address | ipv6 ipv6-address }
undo nas-ip [ ipv6 ]
Default
The source IP address of an outgoing RADIUS packet is that specified by using the radius nas-ip
command in system view. If the radius nas-ip command is not configured, the source IP address is the IP
address of the outbound interface.

Predefined user roles

Parameters
ipv4-address: Specifies an IPv4 address, which must be an address of the device and cannot be 0.0.0.0,
255.255.255.255, a class D address, a class E address, or a loopback address.
ipv6 ipv6-address: Specifies an IPv6 address, which must be a unicast address of the device and cannot
be a loopback address or a link-local address.
Usage guidelines
The source IP address of the RADIUS packets that a NAS sends must match the IP address of the NAS that
is configured on the RADIUS server. A RADIUS server identifies a NAS by its IP address. Upon receiving
a RADIUS packet, a RADIUS server checks whether the source IP address of the packet is the IP address
of a managed NAS. If yes, the server processes the packet. If not, the server drops the packet.
The setting configured by using the nas-ip command in RADIUS scheme view is effective only for the
RADIUS scheme, whereas that configured by using the radius nas-ip command in system view is effective
for all RADIUS schemes. The setting in RADIUS scheme view takes precedence.
If no source IP address is specified for outgoing RADIUS packets, packets returned from the server cannot
reach the device due to a physical port error. HP recommends you to configure a loopback interface
address as the source IP address for outgoing RADIUS packets.
A RADIUS scheme can have only one source IP address for outgoing RADIUS packets. If you specify a
new source IP address for the same RADIUS scheme, the new one overwrites the old one.
