Typical Configuration of v7 Wireless Forwarding Policy Feature.

AC and AP register across three layers, AP performs local forwarding, and DHCP server is deployed on AC.

In the normal situation where the AC and AP register across three layers and the DHCP server is deployed on the AC or local forwarding is used, the terminal cannot obtain an IP address because the terminal"s DHCP request packet is a data packet and cannot be encapsulated by a tunnel to cross three layers. The V5 device has a special command "client dhcp-server centralized" that encapsulates the DHCP request packet sent by the terminal into a tunnel packet. However, this command is not available on V7 devices. In the D029 branch version of V7, the wireless forwarding policy feature can be used to meet this requirement. The configuration method is as follows:

wlan service-template test

ssid test123

vlan 2       

 client forwarding-location ap vlan 2

client forwarding-policy-name test (required)

client forwarding-policy enable(required)

client-rate-limit inbound mode static cir 8200

client-rate-limit outbound mode static cir 8200

portal enable method direct

portal domain dm1

portal apply web-server newpt

service-template enable

#

wlan forwarding-policy test(required)

classifier acl 3001 behavior remote

#

acl advanced 3001(required)

rule 10 permit udp destination-port eq bootps   DHCP packet uses port 67

rule 20 permit udp destination-port eq bootpc   DHCP packet uses port 68

Note:

1. The wireless forwarding policy feature is related to the device model, and it is recommended to first verify whether the device model supports it.

2. The wireless forwarding policy feature requires the establishment of OpenFlow tunnels and the configuration of policy forwarding to be pushed to the AP. If there is a firewall in the on-site networking, it is necessary to open the tcp 6633 port.
