© 2007 Cisco Systems, Inc. All rights reserved.ICND1 v1.0—4-2 Understanding DHCP  DHCP is built on a client-server model, as follows: –The DHCP server hosts allocate network addresses and deliver configuration parameters. –The term "client" refers to a host requesting initialization parameters from a DHCP server.  DHCP supports these three mechanisms for IP address allocation: –Automatic allocation; DHCP assigns a permanent IP address to a client. –Dynamic allocation; DHCP assigns an IP address to a client for a limited period of time. –Manual allocation; A client IP address is assigned by the network administrator, and DHCP is used simply to convey the assigned address to the client.  Dynamic allocation is the only that allows automatic reuse of an address that is no longer needed by the client to which it was assigned.

All rights reserved.ICND1 v1.0—4-15 Summary  DHCP is built on a client-server model.  DHCP server hosts allocate network addresses and deliver configuration parameters.  Cisco IOS Software includes a DHCP server.  Cisco SDM can be used to configure a DHCP server on a router.  The required configuration items are as follows: –Pool name –Pool network and subnet –Starting and ending addresses  Cisco SDM can be used to monitor a DHCP server on the router.  The show ip dhcp conflict command can be used to find conflicts.
