Dynamic Host Configuration Protocol
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.
Specifying a
DHCP Client Identifier
Use the IP Service > DHCP > Client page to specify the DHCP client identifier for a
VLAN interface.
Command Usage
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 daemons configuration file.
