This command is used to identify the vendor class and configuration of the switch to the DHCP
server, which then uses this information to decide on how to service the client or the type of
information to return.

The general framework for this DHCP option is set out in RFC 2132 (Option 60). This
information is used to convey configuration settings or other identification information about a
client, but the specific string to use should be supplied by your service provider or network
administrator. The general framework for this DHCP option is set out in RFC 2132 (Option 60).
This information is used to convey configuration settings or other identification information
about a client, but the specific string to use should be supplied by your service provider or
network administrator. Options 60, 66 and 67 statements can be added to the server
daemon’s configuration file.

By default, DHCP option 66/67 parameters are not carried in a DHCP server reply. To ask for a
DHCP reply with option 66/67 information, the DHCP client request sent by this switch
includes a “parameter request list” asking for this information. Besides, the client request also
includes a “vendor class identifier” that allows the DHCP server to identify the device, and
select the appropriate configuration file for download. This information is included in Option 55
and 124.
