@King_1988 is it your service port cabled? You can try using the service port.

 Can you share the command "show run-condig command"?

[King_1988]

@flavio, here it is. Please ignore the console message.

[Flavio Miranda]

Let me look. Are you able to use the service port or not?  192.168.0.2

[King_1988]

I tried with service port, but still not accessible.

[Flavio Miranda]

If you can ping the service port also and can not access the same way the management interface,  you need to start looking your PC.

Try with another PC, turrn off firewall, anti-virus,  etc.

 The WLC have no ACL and I dont see any config that might prevent you.

[King_1988]

Ok i will check that again. Though i have checked with multiple laptops but got same problem. By any chance HA can be an issue?  as i am getting some logs related to HA failure

[Flavio Miranda]

@King_1988  it could be.

Can you share the command

@King_1988  you do have HA problem.

 I would suggest you take a backup and reload both wlc.

Thats provably your problem

• @Flavio Miranda  thanks a lot. After disabling HA and rebooting the device the issue solved. Another thing we are going to install AIR-DNA license if we form HA after installing license for primary one will license will be synchronised?
