H3C MSR Series Command Reference

103
Usage guidelines
When you enable the RADIUS DAS feature, the device listens to UDP port 3799 to receive DAE
packets from specified DACs.
Examples
# Enable the RADIUS DAS feature and enter RADIUS DAS view.
<Sysname> system-view
[Sysname] radius dynamic-author server
[Sysname-radius-da-server]
Related commands
client
port
radius nas-ip
Use radius nas-ip to specify a source IP address for outgoing RADIUS packets.
Use undo radius nas-ip to delete a source IP address for outgoing RADIUS packets.
Syntax
radius nas-ip { ipv4-address | ipv6 ipv6-address } [ vpn-instance vpn-instance-name ]
undo radius nas-ip { ipv4-address | ipv6 ipv6-address } [ vpn-instance vpn-instance-name ]
Default
The source IP address of an outgoing RADIUS packet is the IP address of the outbound interface.
Views
System view
Predefined user roles
network-admin
Parameters
ipv4-address: Specifies an IPv4 address, which must be an address of the device. The IP address
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.
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the source IP
address belongs. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters.
To configure a public-network source IP address, do not specify this option.
Usage guidelines
The source IP address of 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 the source IP address of the packet is the IP address of a managed NAS, the server
processes the packet.
• If the source IP address of the packet is not the IP address of a managed NAS, the server drops
the packet.
As a best practice to avoid RADIUS packet loss caused by physical port errors, specify a loopback
interface address as the source IP address for outgoing RADIUS packets.
