Specifying a DHCP
DHCP servers index their database of address bindings using the client's Media
Client Identifier Access Control (MAC) Address or a unique client identifier. The client identifier 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.
DHCP client Identifier (Option 60) is used by DHCP clients to specify their unique
identifier. The client identifier is optional and can be specified while configuring
DHCP on the primary network interface. DHCP Option 60 is disabled by default.
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 (vendor-class-identifier), 66
(tftp-server-name) and 67 (bootfile-name) statements can be added to the server
daemon's configuration file as described in the following section.
If the DHCP server has an index entry for a switch requesting service, it should reply
with the TFTP server name and boot file name. Note that the vendor class identifier

image upgrade is enabled by this command, the switch will follow these steps
when it boots up:
a.
It will search for a new version of the image at the location specified by
upgrade opcode path command. The name for the new image stored on
the TFTP server must be ECS4620-28T.bix. If the switch detects a code
version newer than the one currently in use, it will download the new
image. If two code images are already stored in the switch, the image not
set to start up the system will be overwritten by the new version.
b.
After the image has been downloaded, the switch will send a trap message
to log whether or not the upgrade operation was successful.
c.
It sets the new version as the startup image.
d.
It then restarts the system to start using the new image.
