# Specify the source IP address of outgoing portal packets as 9.9.1.1, the virtual IP address of
VRRP group 1.
[SwitchA–Vlan-interface10] portal nas-ip 9.9.1.1
5. Configure portal stateful failover:
# Assign interface VLAN-interface 10 to portal group 1.
[SwitchA–Vlan-interface10] portal backup-group 1
[SwitchA–Vlan-interface10] quit
# Set the device ID for Switch A in stateful failover mode to 1.
[SwitchA] nas device-id 1
# Specify the source IP address of outgoing RADIUS packets as 192.168.0.1, the virtual IP
address of VRRP group 2.
[SwitchA] radius nas-ip 192.168.0.1
Make sure you have added the access device with IP address 192.168.0.1 on the RADIUS server.
6. Configure the stateful failover function:
# Configure the VLAN for stateful failover as VLAN 8.
[SwitchA] dhbk vlan 8
# Enable stateful failover and configure it to support the symmetric path.
[SwitchA] dhbk enable backup-type symmetric-path
Configuring Switch B
1. Configure VRRP:
# Create VRRP group 1, and configure the virtual IP address of the VRRP group 1 as 9.9.1.1.
<SwitchB> system-view
[SwitchB] interface vlan-interface 10
[SwitchB–Vlan-interface10] vrrp vrid 1 virtual-ip 9.9.1.1
# Set the priority of VLAN-interface 10 in VRRP group 1 to 150.
[SwitchB–Vlan-interface10] vrrp vrid 1 priority 150
[SwitchB–Vlan-interface10] quit
# Create VRRP group 2, and configure the virtual IP address of the VRRP group 2 as 192.168.0.1.
[SwitchB] interface vlan-interface 20
[SwitchB–Vlan-interface20] vrrp vrid 2 virtual-ip 192.168.0.1
# Set the priority of VLAN-interface 20 in VRRP group 2 to 150.
[SwitchB–Vlan-interface20] vrrp vrid 2 priority 150
[SwitchB–Vlan-interface20] quit
2. Configure a RADIUS scheme:
# Create RADIUS scheme rs1 and enter its view.
[SwitchB] radius scheme rs1
# Configure the server type for the RADIUS scheme. When using the IMC server, configure the
RADIUS server type as extended.
[SwitchB-radius-rs1] server-type extended
# Specify the primary authentication server and primary accounting server, and configure the keys
for communication with the servers.
[SwitchB-radius-rs1] primary authentication 192.168.0.111
[SwitchB-radius-rs1] primary accounting 192.168.0.111
