Dhcp Server - Supermicro SSE-G24-TG4 Configuration Manual

Supermicro switches support Dynamic Host Configuration Protocol (DHCP) server, DHCP client and DHCP
relay agent functionality.

1.6.1 DHCP Server

The DHCP server implementation in Supermicro switches maintains a database of available IP addresses
and configuration information. When the DHCP server receives a request from a DHCP client, the DHCP
server determines the network to which the DHCP client is connected. The DHCP server then allocates
an IP address or prefix that is appropriate for the client. DHCP servers typically grant IP addresses to
clients only for a limited interval. DHCP clients must either renew their IP address before that interval
has expired or must stop using the address once the interval has expired. The DHCP server can also be
configured to assign additional parameters like default routers, the IP address of the Domain Name
System (DNS) server,etc. The DHCP server can accept broadcasts from locally attached LAN segments or
from DHCP requests that have been forwarded by other DHCP relay agents within the network.

1.6.1.1 DHCP Address Pool
The DHCP server in Supermicro switches accepts requests for address assignment and renewals.
assigns the addresses from predefined groups of addresses contained within DHCP address pools. These
address pools can also be configured to supply additional information to the requesting client such as
the IP address of the DNS server, the default router, and other configuration parameters.
1.6.1.2 Additional Parameter - Default Router & DNS
The DHCP server can be configured to assign additional parameters to the DHCP clients such as the IP
address of the Domain Name System (DNS) server and the default router.
