Cisco IOS and DHCP

[MarkJeffers]

Is the Cisco DHCP server part of the IOS? In other words can any Cisco managed switch or router capable of providing DHCP to include layer 2 managed switches?

Can someone point me to a set of instructions on configuring DHCP on a 3560 Layer 3 switch? I don’t want to do anything fancy, just run DHCP server on a particular block of IP address. Cisco instructions seem to be incomplete.

I’m running IOS 12.2

Is there a “show” command or something similar that will show me the current DHCP configuration?

Thanks for any information you can provide!

This is the config I have on one of my 3560 switches:

ip dhcp excluded-address 192.168.2.1

ip dhcp excluded-address 192.168.2.2

!

ip dhcp pool test

network 192.168.2.0 255.255.255.0

dns-server

default-router 192.168.2.1

As you can see its quite simple. start off with the commands "ip dhcp" in global config mode and see all of the available ones to use. its fairly straight forward from there.

This small article should help you out a little.

this is the working configuration of dhcp server in my office, which will be very simple for you to understand.

domain-name yourcomapny.com

dns-server 10.2.1.1

default-router 10.1.1.252

lease 3

!

ip dhcp snooping

ip dhcp-server 10.187.1.250
