DHCP server configuration examples
DHCP networking involves two types:
• The DHCP server and client are on the same subnet and exchange messages directly.
• The DHCP server and client are not on the same subnet and they communicate with each other via
a DHCP relay agent.
The DHCP server configuration for the two types is the same.
Static IP address assignment configuration example
Network requirements
As shown in Figure 26 , Switch B (DHCP client) obtains the static IP address, DNS server address, and
gateway address from Switch A (DHCP server).
The
client ID of VLAN-interface 2 on Switch B is
3030-3066-2e65-3234-392e-3830-3530-2d56-6c61-6e2d-696e-7465-7266-6163-6532.
