Help with configuring DHCP with VLAN on procurve switch

[chrisjako]

I'm trying to get DHCP to assign ip addresses on my open SSID network using Ubiquiti Unifi AP's (open set to VLAN 2), this is how my HP procurve 5406ZL switch is setup with port B13 being my DHCP server bound NIC and port B23 is my unifi, when i try to connect to my open SSID i am not getting a DHCP address, can anyone help?

ack - you have a positively *ancient* firmware on that switch, I don't even recognise it so can't really advise much :| In the CLI for the switch, do:

conf

vlan 2

dhcp helper-address dhcp.server.ip.here (i.e. dhcp helper-address 192.168.1.1)

write mem

exit

Really? I updated it a few weeks ago

It's K.15.06.0008 now but it shouldn't be a problem.

Is B13 direct into the server? If so that needs to be untagged. Also B23 needs to be untagged in your default vlan. You only tag the wifi vlan. You should have this set in the Unifi wireless config.

[chrisjako]

yes b13 is direct to server

 

in the cli i'm getting invalid input: helper-address

 

new config still not picking up DHCP on my open SSID:

 

 

I have GVRP enhabled this ip range is on a different subnet

Its ip helper-address. Have you typed config t in before to get into the config console? b13 needs to be untagged not auto.

config t worked, if i set it to untagged it sets itself to auto on VLAN 1

 

 

seems to be assigning DHCP address to any device on my network now

On the wireless?

[chrisjako]

no on the wired, wireless still not picking up a DHCP address

[andyrite]

You need to set b13 to no on vlan 1. If you type menu in the cli under switch config : vlan menu : vlan port assignment you can do it in there.

[chrisjako]

B13 set to forbid on VLAN 1

 

my iphone is picking up IP on the secure SSID but still a no go on the open SSID

[andyrite]

Can you post a pic of your unifi wlan config?

Thanks for your help btw!

Note the Ip helper allows 8 different protocols between sub-nets including DHCP.

[andyrite]

Same config as mine but I don't apply any guest policys.

YEY it's now working, I added port B15 to my cisco router default gateway and untagged it on VLAN 2 - now ipads and iphones are picking up open network DHCP - Thanks again andyrite for your assistance
