DHCP Option 82 can be enabled or disabled at four levels: global, port, VLAN,
and service port levels. This function takes effect only after it is enabled at the
four levels. Among the four levels, DHCP Option 82 is disabled only at the global
level by default.

The global level: In global config mode, run the
dhcp option82
command to
enable DHCP Option 82 at the global level.
When you run this command, select the
