DHCP Server
The DHCPv4 Server feature enables you to configure the device as a DHCPv4
server. A DHCPv4 server is used to assign IPv4 address and other information to
another device (DHCP client)
The DHCPv4 server allocates IPv4 addresses from a user-defined pool of IPv4
addresses.
These can be in the following modes:
• Static Allocation—The hardware address of a host is manually mapped to
an IP address.
• Dynamic Allocation—A client obtains a leased IP address for a specified
period of time (that can be infinite). If the DHCP client does not renew the
allocated IP Address, the IP address is revoked at the end of this period,
and the client must request another IP address.
DHCP Options
The following tables defines DHCP options supported by the DHCP server for
which there are dedicated configuration commands, so that they can be
referenced by name.
