cisco packet tracer wlc unable to connect LAPs

[R Manjunatha]

Hi

There is no connection between WLC to LW-AP and there is no capwap connection as well.

1. Packet tracer is a training emulator which may behave differently from a real network.

2. Your APs need connectivity to the WLC and they need to know how to discover the WLC - local subnet broadcast, DNS, DHCP option 43, PnP

3. I notice your AP has 192.168.5.7/24 IP but your DHCP config lists first IP in that subnet as 192.168.9.0 (different subnet) - I wonder if that could confuse your emulator?

[R Manjunatha]

1. Yes, packet tracer is not a real network since I need to practice and there is no other option. even I could not find any simulator for LW-AP in eve-ng as well.

2. wlc gig/1 interface to switch f0/8 interface is trunk mode ? if I talk about the L2 network. Similarly, if I connected wlc L3 network what would be the configuration?  I believe there is no communication between WLC to APs

3. yes its a typographic error and I correct it.

[Rich R]

If the APs and WLC are in the same broadcast domain - which usually means the same VLAN - then the APs can discover the WLC by broadcast.  The AP must have an IP address first - either by static config or DHCP.
That VLAN needs to be the untagged (native) VLAN on the AP switch port and the controller needs to have the management interface on that VLAN.

Hi,

Somewhat I figure out to communicate all APs with WLC and now my wifi end user not getting the DHCP IP address as shown.
