Overview
Use this command to remove one or more DHCP Snooping dynamic entries from
the DHCP Snooping binding database. If no options are specified, all entries are
removed from the database.
CAUTION
: If you remove entries from the database for current clients, they will
lose IP connectivity until they request and receive a new DHCP lease. If you clear
all entries, all clients connected to untrusted ports will lose connectivity.
