Dynamic Host Configuration Protocol (DHCP) can dynamically allocate an
IP address and other configuration information to network clients when
they boot up. If a subnet does not already include a BOOTP or DHCP server,
you can relay DHCP client requests to a DHCP server on another subnet.

The class identifier is used 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. Options 60, 66 and 67 statements can be added to the
server daemon’s configuration file.
