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.
CLI References
• “ip dhcp client class-id” on page 581
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.
