Figure 1-10 Configure re-DHCP portal authentication
Configuration procedure
z
For re-DHCP authentication, you need to configure a public address pool (20.20.20.0/24, in this
example) and a private address pool (10.0.0.0/24, in this example) on the DHCP server. The
configuration steps are omitted. For DHCP configuration information, refer to DHCP Configuration
in the IP Services Volume .
z
For re-DHCP authentication, the switch must be configured as a DHCP relay agent (instead of a
DHCP server) and the portal-enabled interface must be configured with a primary IP address (a
public IP address) and a secondary IP address (a private IP address).
z
You need to configure IP addresses for the devices as shown in Figure 1-10 and ensure that routes
are available between devices.
z
Perform configurations on the RADIUS server to ensure that the user authentication and
accounting functions can work normally.
Configure the switch:
1) Configure a RADIUS scheme
# Create a RADIUS scheme named rs1 and enter its view.
<Switch> system-view
[Switch] radius scheme rs1
# Set the server type for the RADIUS scheme. When using the iMC server, you need set the server type
to extended.
[Switch-radius-rs1] server-type extended
# Specify the primary authentication server and primary accounting server, and configure the keys for
communication with the servers.
[Switch-radius-rs1] primary authentication 192.168.0.113
[Switch-radius-rs1] primary accounting 192.168.0.113
[Switch-radius-rs1] key authentication radius
