To disable DHCP snooping on a specified interface, run the dhcp snooping disable command on this interface. After DHCP snooping is disabled on an interface, users on this interface can go online, but dynamic DHCP binding entries are not generated for the users.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run dhcp snooping disable
