DHCP server in times of need?

OK, say your working on getting the new HP 830 Unified Wired-WLAN controller up and running in a test lab. I know, you’re just like me and like to geek out in the lab…..wear it like a badge of honor. You happen to have the New HP 830 Unified Wired-WALN controller and some access points (MSM-430, MSM-460). The one thing you don’t have is a DHCP server handy in your lab. Fear not! One is closer than you think.

You see, the HP 830 controller actually has an embedded 8 or 24 port gigabit switch. IF you look at the command line for the switch you will see it has all kinds of features and functionality and one of them is a DHCP server.

When you establish a console connection to the controller you will be at the WLAN controller prompt…..<HP>…from this prompt you need to navigate to the prompt for the internal switch. How do you do this? I’m glad you asked. Use the very intuitive command…..oap connect slot 0.

You should now see an identical prompt to the one you were just at <HP>…..from here you can issue the system-view command to get to the [HP] (enabled mode) or CTRL+K to move back to the controller. Let’s stay on the switch prompt and use the system-view to get enabled.

Let’s take a quick peak at what it will take to get it running.

A quick look at the commands.
enable_server

We start off with enabling the DHCP server. Next we specify the name of the server, I used swim2 with the EXTENDED option.
Specify the IP range and mask along with the gateway information. The forbidden IP addresses are optional.

Finally apply the ip-pool to the VLAN interface. In this example it is VLAN 100.

That’s it. You now have a quick and easy DHCP server to use for your LAB environment.
