Wednesday, December 04, Dynamic Host Configuration Protocol CSI 5321 Presented by Junaid Taqui

Wednesday, December 04, What is DHCP ?  Two Components of DHCP  DHCP is built on a client-server model  DHCP supports three modes of IP-Address allocation Automatic Manual Dynamic

Wednesday, December 04, Related Work  RARP  TFTP  ICMP  BOOTP NIP  ARP  RLP

Wednesday, December 04, Definition of useful terms  DHCP client  DHCP server  BOOTP relay agent  Binding  Lease

Wednesday, December 04, op (1) htype (1)hlen (1)hops (1) xid (4) secs (2)flags (2) ciaddr (4) yiaddr (4) siaddr (4) giaddr (4) chaddr (16) sname (64) file (128) options (312) Format of DHCP message

Wednesday, December 04, DHCP Messages  DHCPDISCOVER - Client broadcast to locate available servers.  DHCPOFFER - Server to client in response to DHCPDISCOVER with offer of configuration parameters.

Wednesday, December 04, DHCP Messages  DHCPACK - Server to client with configuration parameters, including committed network address.  DHCPNAK - Server to client indicating client's notion of network address is incorrect (e.g., client has moved to new subnet) or client's lease as expired  DHCPDECLINE - Client to server indicating network address is already in use.

Wednesday, December 04, DHCP Messages  DHCPRELEASE - Client to server relinquishing network address and canceling remaining lease.  DHCPINFORM - Client to server, asking only for local configuration parameters; client already has externally configured network address.

Wednesday, December 04, The Client-Server Protocol  Client-server interaction - allocating a network address  Client-server interaction - reusing a previously allocated network address

Wednesday, December 04, Allocating a network address SERVER CLIENT SERVER DHCPDISCOVER DHCPOFFER DHCPREQUEST DHCPACK DHCPRELEASE
