Currently have a couple of C9800 controllers in a LAB environment for a POC. They both at this time connect to the same switch but on different subnet's so no firewall to consider.
Each WLC can ping each other, yet I am struggling to bring up the mobility tunnel.
Here is controller 1 details:
And the same for the other controller:
Have been following this guide:
That last screenshot in comparison to the other controller is missing the first line. This was there and still didn't work, think it disappeared after a reboot - so thinking it has nothing to do with issue.
Have additionally tried creating a new mobility group (as per URL) and put different MAC on each controller and pointed the peer to that MAC and WLC IP.
I couldn't find any specific debug command that I could use on these controllers, or any detail in the log as to what the problem might be.
Could be a config issue, hence throwing it out their.
Appreciate any assistance in advance.
Thanks for posting a reply.
I tried putting them on the same network, but made no difference.
Run a compare on the configs and noticed quite a bit of difference on one of them, looks like the startup wizard didn't complete properly.
I deleted the WLC and built a new one, and since there seems to be some success.
I see messages display desperately that the data and then the control path was up.
Oddly when I run the 'show wireless mobility summery' its showing the Control Path Down.
So almost there, just not sure why the control path is showing down now.
Anymore ideas, show commands, debug commands I could use to diagnose the issue?
