Wireless Connectivity

Unanswered Question

I am installing 2 WLCs (AIR-WLC4402-50-K9) and 15 AIR-LAP1242AG-A-K9 to replace the existing wireless network which is made of standalone APs (AIR-AP1230B-A-K9). The current wireless users are on VLAN 308. This VLAN has 2 subnets: primary ( and secondary ( as follows:

interface Vlan308
description Wireless Catalyst System
ip address
ip address secondary

The secondary subnet was added to VLAN 308 due to lack of IPs available on the primary subnet to attend all the wireless users.

I am configuring the interface called “ap-client” as follows:

Interface Name            VLAN Identifier                       IP Address Interface
ap-client                        308                                        

I have two questions about this environment?

The first question is:

1)      Will wireless users be able to be assigned to the secondary subnet of this VLAN ( Or will the wireless client only be assigned to the primary subnet (

This site has 26 standalone APs and in the first phase of the project only 15 APs will be replaced by LWAPPs, the remaining 11 standalone APs will have to coexist with the LWAPPs for some time until the second phase of the project, when the remaining 11 APs will be up migrated to LWAPPs

The second question is:

2)      Is it possible to for a WLC and a standalone environment to coexist?

Thanks in advance,
