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, or
configure the DHCP server on this switch to support that subnet.
When configuring the DHCP server on this switch, you can configure an
address pool for each unique IP interface, or manually assign a static IP
address to clients based on their hardware address or client identifier. The
DHCP server can provide the host’s IP address, domain name, gateway
router and DNS server, information about the host’s boot image including
the TFTP server to access for download and the name of the boot file, or
boot information for NetBIOS Windows Internet Naming Service (WINS).
