How to create DHCP server in 2920 Procurve switch

[rka61]

Hi Can somebody confirm if it is possible to setup a DHCP server on a HP 2920 Procurve switch.

This is a L3 switch and I am used to configuring cisco switches. On a 2960 which is a L2 swtich you can do this is very easily.

But on the HP switch I cannot seem to do this. First of all there is no option in the GUI, so I have created a DHCP pool via the CLI but I cannot get the pool to be activated on VLAN 10 "Management"  All I want to acheive is a DHCP pool per VLAN on the switch. I do not know what the DHCP IP address is of the switch? Which VLAN will it listen on.

I saw this post but was not sure if it applies to 2920's and if this is the case I cannot beleive you cannot setup DHCP server on the switch. Really simple configuration.

Here is a copy of my config.

Yes, it is possible. Here is the interesting part of a functioning config. Notice that there is a "dhcp-server" command at the VLAN context and a "dhcp-server enable" command at the global context.

vlan 1

    name "DEFAULT_VLAN"
    ip address 10.1.1.3 255.255.255.0
    dhcp-server
exit
dhcp-server pool "Lab"
     authoritative
     default-router "10.1.1.1"
     dns-server "10.1.1.97,10.1.1.1"
     domain-name "domain.com"
     network 10.1.1.0 255.255.255.0
     range 10.1.1.200 10.1.1.254
exit
dhcp-server enable

Thanks super star that helped me fix it.

Which there was an easier way to do it via the GUI

Hello, somebody know how can I an IP reservation to a specific mac address?

[EricAtHP]

Disable the dhcp server, enter the pool context, and then create a static-binding:

dhcp-server disable

dhcp-server pool "Name"

static-bind ip 10.1.1.254 255.255.255.255 mac aa:bb:cc:dd:ee:ff

exit

dhcp-server enable

Hope that helps.

Re: How to create DHCP server in 2920 Procurve switch

Disable the dhcp server, enter the pool context, and then create a static-binding:

dhcp-server disable

dhcp-server pool "Name"

static-bind ip 10.1.1.254 255.255.255.255 mac aa:bb:cc:dd:ee:ff

exit

dhcp-server enable

Hope that helps.

Would it be possible to disable a single dhcp ip-pool?  If not, does disabling the dhcp server make it so that all of the IPs that were dynamically assigned drop from a network range?

I did not know that you had to disable the server to statically bind MAC addresses, thanks! Kinda scratched my head for a bit wondering why the "static-bind" command was unregognized on my a7510 core switch.

Hello,

how can i exclude 4 ip address ?

[fixitrod]

Use multiple Range commands to exclude-addresses. Here's an example of a range from 192.168.10.100 to .200 excluding .151 to .155. Also, I added a lease time since it wasn't shown above. Lease time is 30 days, 20 hours, 10 minutes. 

Note: disabling the DHCP server only stops the switch from handing out IP addresses during that time. It does not break addresses already given. If you put all your commands in a text editor like notepad then copy and paste to the switch it will be down for less than a couple seconds and in most environments, it won't be noticed.
