WLAN IP snooping commands
client ip-snooping http-learning enable
Use client ip-snooping http-learning enable to enable snooping HTTP and HTTPS requests redirected to the portal server.
Use undo client ip-snooping http-learning enable to disable snooping HTTP and HTTPS requests redirected to the portal server.
Syntax
client ip-snooping http-learning enable
undo client ip-snooping http-learning enable
Default
Snooping HTTP and HTTPS requests is disabled.

Usage guidelines
An AC can use this method to learn IP addresses of clients performing portal authentication. For more information about portal authentication, see User Access and Authentication Configuration Guide.
The priorities for learning IP addresses through snooping DHCP packets, ARP or ND packets, and HTTP/HTTPS requests are in descending order.
Make sure the service template is disabled when you execute this command.
Examples
# Enable snooping HTTP and HTTPS requests.
<Sysname> system-view
[Sysname] wlan service-template service1
[Sysname-wlan-st-service1] client ip-snooping http-learning enable
client ipv4-snooping arp-learning enable
Use client ipv4-snooping arp-learning enable to enable snooping ARP packets.
Use undo client ipv4-snooping arp-learning enable to disable snooping ARP packets.
Syntax
client ipv4-snooping arp-learning enable
undo client ipv4-snooping arp-learning enable
Default
Snooping ARP packets is enabled.

client ipv4-snooping dhcp-learning timeout
Use client ipv4-snooping dhcp-learning timeout to enable forced logoff of clients that fail to obtain an IPv4 address through DHCP within the specified timeout.
Use undo client ipv4-snooping dhcp-learning timeout to disable forced logoff of clients that fail to obtain an IPv4 address through DHCP.
Syntax
client ipv4-snooping dhcp-learning timeout value
undo client ipv4-snooping dhcp-learning timeout
Default

Parameters
value: Specifies the timeout in the range of 1 to 600 seconds.
Usage guidelines
This command takes effect only on clients that come online from the AC after the command execution.
Examples
# Enable forced logoff of clients that fail to obtain an IPv4 address through DHCP and set the timeout to 180 seconds.
<Sysname> system-view
[Sysname] wlan service-template 1
[Sysname-wlan-st-1] client ipv4-snooping dhcp-learning timeout 180
client ipv6-snooping dhcpv6-learning enable
Use client ipv6-snooping dhcpv6-learning enable to enable snooping DHCPv6 packets.
Use undo client ipv6-snooping dhcpv6-learning enable to disable snooping DHCPv6 packets.
Syntax
