Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

Hi everyone,

We have two 5500 wireless controllers that we use for ~80 APs.  We just installed the new system a month or so ago.  When all the APs were replaced, they updated from the new controller and all joined the first controller.  I cannot get any of them (except 1) to join the 2nd controller.  I even set the primary controller to be the 2nd one on a few of the APs, reset them, and they still do not join it. 

The only one that does join it is on VLAN 6 (wireless vlan) and all the rest are on VLAN 5.  I do not have a DHCP option set but from what I have been reading I was under the impression that I did not need to have one set with this model of AP. 

I am fairly new to wireless so please forgive me but I do not know what information I need to provide you guys with to help me. If you are able to help, just let me know what I need to get for you and I can do that.

Thanks in advance!

Edit:  This is showing up on the 2nd controller for one of the APs I tried to force onto it.

Re: Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

You should have two entries that show UP, you only have one and if you do a show interface detailed management, you will see that that mac address is itself.  You need to add an entry for the other WLC.  This is how it should look.

Example:

Controllers configured in the Mobility Group

MAC Address        IP Address       Group Name                        Multicast IP     Status

00:1e:4a:ff:1b:20  *.*35.248    dummy                             0.0.0.0          Control and Data Path Down

7c:ad:74:8d:37:e0  *.*.71.248    dummy                             0.0.0.0          Up

7c:ad:74:8d:73:00  *.*.71.246    dummy                             0.0.0.0          Up

Controllers configured in the Mobility Group

MAC Address        IP Address       Group Name                        Multicast IP     Status

00:1e:4a:ff:25:e0  *.*.35.246    dummy                             0.0.0.0          Control and Data Path Down

7c:ad:74:8d:73:00  *.*.71.246    dummy                             0.0.0.0          Up

7c:ad:74:8d:37:e0  *.*.71.248    dummy                             0.0.0.0          Up

Thanks,

Re: Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

are you putting ap in a dynamic interface vlan?

Re: Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

I believe they are connecting to a Dynamic Interface VLAN.

Re: Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

that is not a good idea.  The AP should be on their own VLAN, and it should not exist as a dynamic interface on the WLC.

Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

So you have two WLC's and they are on the same subnet correct?  Do you have mobility setup between the two wlc's and are they using the same mobility group name?  This is important if you want the AP's to know about the othe WLC.

Thanks,

Scott

Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

This is really a reply to both of you, and thanks for your help.  I do not know if mobility is set up between the two, and I am not sure how to check.  When we upgraded the wireless controllers, we copied the config from the old ones to the other.

They are on the same subnet.

I was part of the upgrade to the new controllers, but I kind of followed along and didn't really do any of the setup.  The network is now in my hands, though.

You can't just copy those... as it has the managment mac address tied to an ip address.  Look at these docs:

Re: Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

We went through and changed those to the new ip range and everything.  They work fine right now but the access points won't split between the two controllers.

Edit:  I know we never did anything with mobility groups, but each controller has the other controller in the mobility group.  It shows up when I run the sh mobility summary command.

Re: Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

You need to manually adding the primary and secondary. As long as the mobility is up between the two wlc's you should have no issues. They will not split up automatically. You need to go in the AP and under the high availability set the primary and secondary WLC information. It is case sensitive also.

I have already done this, and they do not go to the 2nd controller.

Post your show mobility summary from both wlc's.

Re: Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

Here is a link to a doc specific to setting and verifying ap failover. Ap fallback also needs to be enabled. Not knowing what you have configured makes it hard to troubleshoot.

So you can see here, that your mobility is not up:

Control and Data Path Down

So you need to fix this and your mac address, don't match?  The mac address of the top WLC is 7c:ad:74:8d:37:e0 and the bottom one is 7c:ad:74:8d:73:00, so both of these need to be in the mobility group configuration.

Re: Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

Those are the old ones from the old controller, the new ones are up and say they are up on the 2nd line.

The ------------------------------ Line separates the controllers, controller 1 on top and controller 2 on bottom.

You should have only two entries.... one for each wlc.  So each wlc has to be entered in the other mobility group.

They are... they just have the old mobility group in there from the old controllers.  But the new ones are still there and they say they are up and working..

I posted it a few posts ago.  I went ahead and bolded the important information.

Re: Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

That makes more sense.  How come there is one AP that is able to get on controller 2 then?  Any ideas?  I will add this when I am at work tomorrow and let you know how it goes.

Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

That is because it joined that WLC... now try to move it to the other WLC and you will run into the same issue... it will not move.

I did that and it lists them as

Control and Data Path Down

How do I get them to come up?

Re: Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

Are they on the same subnet, if not, make sure you have no acl firewall that so blocking the traffic.

They are in the same subnet.

Re: Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

If they are in the same subnet and you have issues, then delete the entries and add them back. In each WLC if you are doing this from the GUI, the top entry is the entry for the WLC you are in, so you copy that and add that to the other WLC and vice versa. Sometimes it works when you remove everything and add it back.

Also, you should be able to mping and eping from one WLC to another from the CLI. This is different from a regular ping. Make sure though you can ping the other WLC. If not, them you need to troubleshoot that.

Re: Can't move AIR-CAP1602I-A-K9 APs to 2nd controller?!

Removed all but the self entries, copied and pasted and still down.

Edit: I am able to ping the other entry with the little drop down box in the GUI

Edit 2:  They are up now.  Should I be good to go?
