WLC 7.4.100 NAT IP Address field missing

[grabonlee]

Hi

I know that very few people have their wireless controllers on version 7.4.100. But has any one noticed that the NAT IP address field in the management interface configuration menu is missing?, although it is mentioned as being present in the WLC 7.4 configuration guide. This would definitely affect Office-Extend.

I just thought I ask before I raise the issue with Cisco TAC.

Is it really "missing"? Or just greyed out?

Because it is greyed out when doing AP-SSO (HA). You have to configure NAT IP before enabling AP-SSO, then it works as expected.

It is not greyed out. It is simply missing. My WLC is on the DMZ, hence I have no need for HA or to have APs associated except OEAPs. Please see attached.

Hello Osita,

As per your query i can propose you the following solution-

Control which address(es) are sent in CAPWAP discovery responses when NAT is enabled on the Management Interface using the following command:

config network ap-discovery nat-ip-only {enable | disable}

where:

–enable— Enables use of NAT IP only in a discovery response. This is the default. Use this command if all APs are outside of the NAT gateway.

–disable—Enables use of both NAT IP and non-NAT IP in a discovery response. Use this command if APs are on the inside and outside of the NAT gateway; for example, Local Mode and OfficeExtend APs are on the same controller.

For more information refer to the link-

Hope this will help.

Abhishek,

Thanks for the suggestion, but I think you missed the point. What you describe occurs only after you have enabled NAT IP, and is only required if a single controller handles both Office Extend APs and CAPWAP APs.

Anyway, I have resolved the problem. Dynamic Management of APs must be enabled on the Management interface or Dynamic Interfaces to make the NAT IP field appear.
