<div>
Can the DHCP server ping the router IP on VLAN 22?
</div>


<div>
Yes! It's reachable.<br />
<br />
The thing is that I have another SSID (but without flexconnect) working on the same VLAN22, and it's working well. The problem is the SSID with flexconnect, the clients connected on it, don't receive any IP from dhcp. I checked the logs on the dhcp server and didn't found any trace.
</div>


<div>
OK, can you give a client a static IP while connected to the FlexConnect SSID and try to ping the IP of the router?<br />
<br />
The port config looks good for the AP. &nbsp;Is the WLC connected to the same switch as the AP? &nbsp;If not, could you show the <b>show vlan brief</b> output please from the switch where the AP connects, and the trunk link config?
</div>


<div>
I gave an static IP while I connected to the flex SSID and the ping to the IP router was not working.<br />
I don't think that the problem is on the trunk or swtich configuration... I believe is 100% flexconnect configuration.<br />
<br />
If I connect to the same flexconnect SSID but through an AP where flexconnect is not configured, the SSID is working fine, it assigns me a valid IP (Vlan22).<br />
<br />
I attach images showing my flexconnect configuration on the WLC,<br />

This is why I asked whether the AP is on the same switch as the WLC or not.<br />
<br />
When you don't use FlexConnect all the traffic from the AP tunnels back to the WLC, so if the VLAN isn't on the switch where the AP connects it doesn't matter, if the WLC and AP are on different switches.<br />
<br />
<u>I need to know</u> whether the AP and WLC are on different switches or not as the config you have at the WLC looks good to me. &nbsp;The only thing I'm curious about really is why you're telling the AP to use AP-specific FlexConnect config, instead of simply using the Group config?
</div>


<div>
The AP is in a different switch as the wlc. <br />
<br />
WLC is connected on a layer 3 cisco catalyst 4500 model.<br />
AP is connected on a layer 2 cisco 2960 model.<br />
<br />
I'm assuming that the AP takes the flexconnect config from the Group config. Where did you see that? I've checked again and everything seems to be correct.<br />
<br />
Any thoughts? Do they have to be on the same switch?
</div>


<div>
They don't have to be on the same switch.<br />
<br />
Can I ask, why are you using FlexConnect?
</div>


<div>
Sure!<br />
I just have one WLC working in the office and wanted to avoid that all AP stop working if the WLC crashes someday.<br />
<br />
And the second intention is to implement flexconnect in remote offices where there is no WLC present.
</div>


<div>
Solved!! :)<br />
The problem was that the command 'vlan 22' was not present on the switch L2.<br />
<br />
Thank you for your support!!

FlexConnect and WLC5508

Wireless networking is anything related to the transfer of data between two (or more) devices without the use of a physical connection, ranging from getting advice on a new Bluetooth headset to configuring sophisticated enterprise level networks.

Wireless Networking

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.

Windows Networking

Wireless networking is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure. The key hardware components of a wireless computer network include adapters, routers and access points, antennas and repeaters.
