Conguration notes for creating an address pool
• If the DHCP server address is part of a congured DHCP address pool, you must exclude the DHCP server address from the
network pool. Refer to Specifying addresses to exclude from the address pool on page 91.
• While in DHCP server pool conguration mode, the system will place the DHCP server pool in pending mode and the DHCP
server will not use the address pool to distribute information to clients. To activate the pool, use the deploy command. Refer to
Deploying an address pool conguration to the server on page 90.
Enabling relay agent echo (option 82)
The ip dhcp-server relay-agent-echo enable command activates DHCP option 82, and enables the DHCP server to echo relay agent
information in all replies.
device(config)# ip dhcp-server relay-agent-echo enable
Syntax: ip dhcp-server relay-agent-echo enable
Conguring the IP address of the DHCP server
The ip dhcp-server command
species the IP address of the selected DHCP server, as shown in this example:
device(config)# ip dhcp-server 10.1.1.144
Syntax: ip dhcp-server
server-identier
• server-identier - The IP address of the DHCP server
This command assigns an IP address to the selected DHCP server.
Conguring the boot image
The bootle command species a boot image name to be used by the DHCP client.
device(config-dhcp-cabo)# bootfile foxhound
In this example, the DHCP client should use the boot image called "foxhound".
Syntax: bootle name
Deploying an address pool
conguration to the server
The deploy command sends an address pool conguration to the DHCP server.
device(config-dhcp-cabo)# deploy
Syntax: deploy
Specifying default routers available to the client
The dhcp-default-router command
species the IP addresses of the default routers for a client.
Syntax: dhcp-default-router address [address, address]
