Usage Guidelines

Usage Scenario

After an AP (DHCP client) obtains an IP address through DHCP, this function enables the DHCP Discover and DHCP Request packets sent by the AP to carry the Option 12 field. The Option 12 field can contain the AP type, MAC address or the AP name. After the AP obtains an IP address through DHCP, you can check information about the AP with this IP address on the DHCP server that supports display of DHCP client host information.

Precautions

This function is valid only for the APs that obtain IP addresses through DHCP.

Example

# Configure the AP name contained in the Option 12 field carried in DHCP packets sent by APs.
