H-REAP Quick question

Hi Team

On the WLC config guide 7.0, page 15-2 under H-REAP Authentication process it is mentioned that DHCP option 43 can be used to discover APs.

However, on page 15-4 under H-REAP guidelines it is mentioned that you need a local DHCP to provide IPss for the APs.

As this is bit confusing,can someone clarify  whether we could use  option 43 with a DHCP server  located in the head office over the WAN link to provide IPs  for the remote-office APs in a H-REAP setup pls?

Thanks,

janesh

Re: H-REAP Quick question

Hi Janesh,

Yes i agree with you.. it is confusing.. lemme help you out..

There are many ways to tell the AP to grab the IP.. both the methods which you have mentioned is correct. that is.. option 43 does work for HREAP APs and the server is central site... we prefer the local DHCP pool.. but Local pool is an another option.

Both the above method may need the Priming the AP.. that is...  the need to ship H-REAPs twice: once to a central site for       provisioning and a second time to the remote site for installation..

To overcome this the static addressing has begun after 4.0 WLC software release.. whic will overcome the provisioning the AP once on the central and other on the remote..

But all the 3 methods are valid and can be used..

Option 43 is the way to go ... Simply create the option on the SCOPE that will hand the IP address to the AP. The AP will then find its way home !

Re: H-REAP Quick question

Hi Janesh,

We are not just assigning the static IP address t othe AP where in we are telling the AP to joing the WLC as well.. that is we are specifying the WLC Managemnt int ip as well.. the commnads are.. So that the AP wil try to register to the WLC IP which is mentioned..

AP_CLI#lwapp ap hostname ap1130
ap1130#lwapp ap ip address 10.10.10.51 255.255.255.0
ap1130#lwapp ap ip default-gateway 10.10.10.1
ap1130#lwapp ap controller ip address 172.17.2.172
