Nas-Backup-Ip - HP 3600 v2 Series Command Reference Manual

By default, a switch works in standalone mode and has no device ID.
Configuring or changing the device ID of a switch logs out all online users of the switch.
The two switches working in stateful failover mode must use the device IDs of 1 and 2 respectively.
The device ID is the symbol for stateful failover mode. A switch working in standalone mode does not
require any device ID.
Examples
# Configure the switch, which is intended to work in stateful failover mode, to use the device ID of 1.
<Sysname> system-view
[Sysname] nas device-id 1
Warning: This command will cut all user connections on this device. Continue? [Y
/N]
The other switch for stateful failover must be configured to use the device ID of 2.

nas-backup-ip

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 outgoing RADIUS packets. It must be the source IP address for
outgoing RADIUS packets that is configured on the other switch 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 a backup source IP address for outgoing RADIUS packets in
a stateful failover scenario.
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.
With a backup source IP address configured for outgoing RADIUS packets, a switch for stateful failover
sends this address to the RADIUS server if it is the active switch. When the active switch fails, the RADIUS
server can send unsolicited RADIUS packets to the standby switch.
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.
NOTE:
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.
