Usage Scenario
When users go offline or entries in the dynamic DHCP snooping binding table need to be deleted, you can run the reset dhcp snooping bind-table command to delete the entries.
Precautions
Check whether the dynamic binding entries must be deleted before running this command. If the dynamic binding entries are forcibly deleted, the users with the IP addresses in these entries are disconnected from the device.
