undo nas-backup-ip
Default
A RADIUS scheme is configured with no backup source IP address for outgoing RADIUS packets.
Views
RADIUS scheme view
Default command level
2: System level
Parameters
ip-address: Backup source IP address for outgoing 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, or a class E address.
Usage guidelines
The following matrix shows the command and router compatibility:
Command 6602 HSR6602 6604/6608/6616
nas-backup-ip Yes Yes No
With a backup source IP address configured for outgoing RADIUS packets, a device for stateful failover
sends this address to the RADIUS server if it is the active device. When the active device fails, the RADIUS
server can send unsolicited RADIUS packets to the standby device.
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 overwrites the old one.
The setting configured by the nas-backup-ip command in RADIUS scheme view is only for the RADIUS
scheme, whereas the setting configured by the radius nas-backup-ip command in system view is for all
RADIUS schemes. The setting in RADIUS scheme view takes precedence.
Examples
# For a device working in stateful failover mode, set the source IP address and backup source IP address
for outgoing RADIUS packets to 2.2.2.2 and 3.3.3.3, respectively.
<Sysname> system-view
[Sysname] radius scheme radius1
[Sysname-radius-radius1] nas-ip 2.2.2.2
[Sysname-radius-radius1] nas-backup-ip 3.3.3.3
On the backup device, you must set the source IP address and backup source IP address for outgoing
RADIUS packets to 3.3.3.3 and 2.2.2.2, respectively.
