4400 WLC with multiple VLAN & SSID

Hello,

Have a sports event coming up and have a Cisco WLC 4400 that I want to deploy with multiple VLANS and SSID's.  I have a router with VLANs as such:

0     Management     192.168.1.x

10     Staff          192.168.10.x

20     Spare          192.168.20.x

30     Timing          192.168.30.x

40     Athletes     192.168.40.x

50     Public          192.168.50.x

The router has DHCP pools for each VLAN, and a trunk going to a 3560 POE switch.  I have ports 1-5 configured for VLAN 10-50 respectively, and plugging into them I can get an IP address and ping the router.

Now I need to expand this down to the WLC, so that I can deploy 12 LWAP's with SSID's of Staff, Timing, Athletes, and Public on their respective VLAN's.  How to configure this?  Is it better to have the WLC be the DHCP server or can I keep that on the router so that wired clients are also serviced?

Thanks,

Eric

4400 WLC with multiple VLAN & SSID

I would use the WLC dhcp only if I can't use any other dhcp.. Typically guest, I would use the WLC dhcp, but nothing else.

To get this to work, you need to connect the WLC into the switch on a trunk port.  Now if LAG is enabled on the WLC, you can connect all the WLC as an etherchannel.  You need to create a dynamic interface on the WLC with an ip address dedicated to the WLC dynamic interface.  So if your router has this:

0     Management     192.168.1.1

10     Staff          192.168.10.1

20     Spare          192.168.20.1

30     Timing          192.168.30.1

40     Athletes     192.168.40.1

50     Public          192.168.50.1

Your WLC dynamci interface can be this if not used:

0     Management     192.168.1.5

10     Staff          192.168.10.5

20     Spare          192.168.20.5

30     Timing          192.168.30.5

40     Athletes     192.168.40.5

50     Public          192.168.50.5

4400 WLC with multiple VLAN & SSID

Thanks I followed the document and will test.  What about "Dynamic AP Management"?  It seems I can't turn that on.  Will I be OK without it?

Re: 4400 WLC with multiple VLAN & SSID

Leave the ap manager tied to the same subnet as the management. Don't create separate ap managers.

4400 WLC with multiple VLAN & SSID

OK so I followed the document and I have the WLC able to ping through all the VLAN's up through the 3560 switch then up to the router, and vice-versa.  I've plugged one AP into the Cisco switch, but it's not finding the WLC.  It's currently flashing green, yellow, red.  I have the port on the switch configured to be a trunk.  Do I need to do anything else?

Re: 4400 WLC with multiple VLAN & SSID

Make sure the time is set properly on the WLC. Try putting the ap on the same subnet as the WLC managemt and make sure the Ap gets a DHCP address.

Post the output fr the ap console also from when you reboot the ap and letting it run for about 5 minutes.

Re: 4400 WLC with multiple VLAN & SSID

Did you created pool on router for APs to get IP???

If yes then did you configure the Option 43 ???

Re: 4400 WLC with multiple VLAN & SSID

AP should be configured as access ports.
Please try to keep AP and WLC on one subnet.

Re: 4400 WLC with multiple VLAN & SSID

Here are other methods of having the ap find the WLC, but placing the ap on the WLC management subnet is the easiest. Once it joins, you can move it to another subnet.

Re: 4400 WLC with multiple VLAN & SSID

Also paste the sh version form AP.If you can not then can you tell me which version AP it is?? means the AP series like 11140 or 1242 or 1250 series???

As per your last logs from AP says that it is 1140 AP , is it right ?

Re: 4400 WLC with multiple VLAN & SSID

Means you have 1140 series AP.

Manufacturer's Name.............................. Cisco Systems Inc.

Product Name..................................... Cisco Controller

Product Version.................................. 5.0.148.0

RTOS Version..................................... Linux-2.6.10_mvl401

You need minimum software version on WLC"5.2.157.0" for these AP to connect to WLC.

Please update to 7.0. seres to WLC and then try again.

Check here the compatibilty matrix :

Cr@p, that's one buggy software.

If you are able to download the firmware from the Cisco website, use 7.0.240.X.

*Mar  1 00:15:07.169: %CAPWAP-3-ERRORLOG: Not sending discovery request AP does not have an Ip !!

AP not getting an IP address.

In enable mode, use this command "capwap ap ip address ".

Re: 4400 WLC with multiple VLAN & SSID

I don't have access to the Cisco website unfortunately

The IP address error showed up because I had the WLC unplugged.  It's picking up an IP and registering now, just not downloading the tar file.

As Sandeep has pointed out, the WLC software does NOT support the AP you are using.  You need to upgrade the firmware of the WLC.

Re: 4400 WLC with multiple VLAN & SSID

Yeah... you should look at the WLC2504 with a 15 license or 25 license.  Those run pretty cheap and you can request the image you want and also you should be able to get support for 90 days.

You can ask your supplier or support partner to provide the 7.0.X series software for WLC. Surely then can!

Re: 4400 WLC with multiple VLAN & SSID

Ok, have made some progress.  I now have the WLC upgraded to 6.0.182.0 and my AP's are registering and broadcasting SSID's.

Now the problem is I can get connected to the WLAN, but no DHCP or throughput.  My WLC can ping all the way to the router which has DHCP pools for all the VLAN's, and I've configured the "Primary DHCP Server" ip setting under Controller -> Interfaces, but still no IP address is assigned.  I've also removed this setting and setup a DHCP pool on the WLC itself, still nothing.  If I manually assign the IP on the client devices, I cannot ping the WLC interface or anything else.  What am I missing?

Thanks,

Eric

Re: 4400 WLC with multiple VLAN & SSID

did you enabled dhcp proxy on wlc ?

via GUI:

Controller->Advanced->DHCP 

via the CLI:

Config dhcp proxy enable

Actually, I had to disable proxy and now it's working!

Re: 4400 WLC with multiple VLAN & SSID

If you areusing external dhcp server or dhcp bridging then you have to disable it configure the ip helper command.
