Set the switch to automatically reboot and load the new code after the opcode
upgrade is completed.
Console(config)#upgrade opcode reload
Set the switch to automatically upgrade the current operational code when a
new version is detected on the server. When the switch starts up and automatic
image upgrade is enabled by this command, the switch will follow these steps
when it boots up:
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 EX3524_Op.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.
After the image has been downloaded, the switch will send a trap message
to log whether or not the upgrade operation was successful.
It sets the new version as the startup image.
It then restarts the system to start using the new image.
Console(config)#upgrade opcode auto

DHCP servers index their database of address bindings using the client's Media
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.
