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).
