IAP - DHCP and VLAN Errors

Hi everybody,

I have a customer where I'm changing old Funkwerk AP with new Aruba 104 IAP.

This customer has 3 WLAN running, 1 for devices (WEP) 1 for enterprise access (WPA Enterprise) and 1 for guests.

I have a problem with the Enterprise one.

The enterprise network has 2 radius authentication servers, and the dynamic radius proxy is enabled on the IAP.

I can see that clients can connect to the network, seems to be correctly authenticated, but they cannot get the IP address.

Watching the alerts window on the IAP console i can find those errors:

"Wrong client VLAN"

"DHCP Request timeout"

 

I already verified that the VLAN ID on the IAP and also on the switch ports (The switch is an HP Procurve 5412zl) are correct, in fact the old APs worked correctly.

I also tried to clean the config and re-configure from scratch all the AP but nothing changed...

 

 

Any ideas?

 

Thanx a lot in advance!

 

Regards!

Re: IAP - DHCP and VLAN Errors

On the uplink switch did you trunked the needed ?

What's the native VLAN on your uplink switch ?

Also on the said config are you doing static VLAN assignment (network assigned)?
Thank you

Re: IAP - DHCP and VLAN Errors

HI Victor, thanx for reply.

Yes, i did the trunk configuration on the switch ports where the IAP are connected.

In HP terminology, I have the VLAN1 as "untagged" and the VLAN3 (the enterprise one) as "tagged".

 

The native vlan of my switch is the VLAN1 and is also the vlan of the IAP Management uplink.

 

My VLAN configuration is done as static (network assigned).

Re: IAP - DHCP and VLAN Errors

What IAP OS version are you using ?
Thank you

Re: IAP - DHCP and VLAN Errors

Try creating a wired port profile as a trunk for port 0

Also try creating a centralize dhcp scope l2 and define the VLAN with IP helper address (dhcp server)
Thank you

Re: IAP - DHCP and VLAN Errors

Thanx for suggestion, I created the Centralized pool and configured the HelperAddress, but how can I create the trunk port profile?

I don't want to risk to loose access on the IAP 'cause I'm in a remote site location...:smileyhappy:

Re: IAP - DHCP and VLAN Errors

 

You actually should be all set since the default wired port profile is setup that way :

wired-port-profile default_wired_port_profile
switchport-mode trunk
allowed-vlan all
native-vlan 1
uplink-enable
no shutdown
access-rule-name default_wired_port_profile
speed auto
duplex full
no poe
type employee
auth-server InternalServer
captive-portal disable
no dot1x

 

 

Thank you

Re: IAP - DHCP and VLAN Errors

I can confirm that the wired profiles are in default settings, none changed.

As soon as I can connect to the IAP I'll dump the config and post here.

 

It's possible that is a problem derived from the LLDP protocol?
