DHCP Client
The switch will automatically obtain an IP assignment from a DHCP Server. Communication between the
client and server can optionally go through a DHCP Relay Agent.
DHCP Relay Agent
DHCP Relay Agent (Option 82) allows communication between the client and server to cross subnet and
VLAN boundries. It also allows for a device on a specific port to receive a specific IP address and if the
device is replaced, the replacement receives the same IP address as the original device.
DHCP Server
DHCP Server allows DHCP Client devices to automatically obtain an IP assignment. IP assignments can be
set up as a dynamic range of IP addresses available to any client device; or specific IP addresses based on
the clients MAC address, Client ID (Option 61), or Relay Agent connection (Option 82).
