Disabling DHCP snooping on an interface

This feature allows you to narrow down the interface range where DHCP snooping takes effect. For example, to enable DHCP snooping globally except for a specific interface, you can enable DHCP snooping globally and disable DHCP snooping on the target interface.

1. Enter system view.

   system-view

2. Enter interface view.

   interface interface-type interface-number

3. Disable DHCP snooping on the interface.

   dhcp snooping disable

   By default:

   • If you enable DHCP snooping globally or for a VLAN, DHCP snooping is enabled on all interfaces on the device or on all interfaces in the VLAN.

   • If you do not enable DHCP snooping globally or for a VLAN, DHCP snooping is disabled on all interfaces on the device or on all interfaces in the VLAN.
