DHCP Local Relay Settings

The DHCP local relay settings allows the user to add Option 82 into DHCP request packets when the DHCP client
gets an IP address from the same VLAN. If the DHCP local relay settings are not configured, the Switch will flood the
packets to the VLAN. In order to add Option 82 into the DHCP request packets, the DHCP local relay settings and the
state of the Global VLAN need to be enabled.
