nas-backup-ip (available only on the A5500 EI)

Syntax
nas-backup-ip ip-address
undo nas-backup-ip
View
RADIUS scheme view
Default level
2: System level
Parameters
ip-address: Backup source IP address for RADIUS packets. It must be the source IP address for outgoing
RADIUS packets that is configured on the other device for stateful failover and cannot be 0.0.0.0,
255.255.255.255, a class D address, a class E address, or a loopback address.
Description
Use the nas-backup-ip command to specify the backup source IP address for outgoing RADIUS packets.
Use the undo nas-backup-ip command to restore the default.
By default, a RADIUS scheme is configured with no backup source IP address for outgoing RADIUS
packets.
After you configure the backup source IP address for RADIUS packets, the local device, if active, will send
it to the RADIUS server so that the RADIUS server also sends unsolicited RADIUS packets to the standby
device. This ensures that when the active device fails, the standby device can receive and process the
RADIUS packets from the RADIUS server.
A RADIUS scheme can have only one backup source IP address. If you specify a new backup source IP
address for the same RADIUS scheme, the new one will overwrites the old one.
NOTE:
The setting by the nas-backup-ip command in RADIUS scheme view is only for the RADIUS scheme,
whereas the setting by the radius nas-backup-ip command in system view is for all RADIUS schemes.
The setting in RADIUS scheme view takes precedence.
Related commands: nas-ip and radius nas-ip.
