Make sure the service template is enabled before you execute this command.
This configuration takes effect only on clients coming online afterwards from the AC.
Examples
# Set the timeout to 180 seconds for IPv4 address learning through DHCP.
<Sysname> system-view
[Sysname] wlan service-template 1
[Sysname-wlan-st-1] client ipv4-snooping dhcp-learning timeout 180
