3550 Configuration of DHCP, the network has many discussions, but most of the existence of errors and omissions, according to the configuration of the online introduction of "IP helper-address DHCP server address", the project found that the client can not obtain the IP address from the DHCP
Windows 2008 Server builds DHCP service:
DHCP is an abbreviation for Dynamic host Configuration Protocol, the predecessor of which is BOOTP. BOOTP was originally used for a network without disk host connection: The network host uses the boot ROM instead of the disk to start and connect to the network, BOOTP can automatically set the TCP/IP environment for those

The implementation of Cisco ios dhcp Server is reflected in many large networks. So today, let's take a look at this part in detail. Nowadays, large networks usually use layer-2 switches for Mbit/s or Gbit/s to switch to the desktop), and divide VLANs on layer-2 or layer-3 switches, then, a layer-3 switch with the line rate routing technology is used to quickly forward data streams between VLANs in the Intr

DHCP is used for dynamic allocation of IP address services, when a network of more computers, we need to manually set the IP address for each client, subnet mask, DNS and gateway and other addresses, operation is very troublesome. With DHCP we can be a dedicated DHCP server
In some DHCP server configurations, we need to understand the network structure and some parameters of the corresponding routers and switches. Next we will summarize this part of content.

For the wan nic, we configure the IP address and mask for it, without configuring the gateway and DNS.
For LAN NICs, the IP address and mask are also configured. Because it is 10 private network segments, the mask can be used by default.
Then we set up AD because we need to deploy DHCP, and DHCP requires AD to operate normally.
Then we select the DHCP
