Usage Guidelines

Usage Scenario

After DHCP snooping is enabled, the mapping DHCP snooping binding entries are generated after DHCP users log in. The reset dhcp snooping user-bind command clears binding entries mapping a specified parameter. If no parameter is specified, all the binding entries are cleared.

Precautions

If both interface interface-type interface-number and vlan vlan-id are configured, the interface specified by interface interface-type interface-number must have been added to the VLAN specified by vlan vlan-id. In this case, the command clears the DHCP snooping binding entries on a specified interface belonging to a certain VLAN.

Example

# Clear DHCP snooping binding entries in VLAN 100.

<Huawei> reset dhcp snooping user-bind vlan 100
