ip helper enable

Use this command to enable relay of UDP packets. This command can be used to temporarily disable IP helper without deleting all IP helper addresses. This command replaces the bootpdhcprelay enable command, but affects not only relay of DHCP (Dynamic Host Configuration Protocol) packets, but also relay of any other protocols for which an IP helper address has been configured.
