Cisco Switch Configuration

A cisco switch has trunk port connecting to other switches. When I connect a Cisco Wireless Controller 2504 to this switch (which support several VLANs), should I also need to configure a trunk link on controller and switches. Is it possible for one trunk to switch and one trunk to controller on this Cisco switch ?

AP will be connected to this Cisco Switch. How does Wireless controller be configured to manage this AP ? Any example ?

Any time you connect 2 devices that each support multiple VLAN's, the link between them will need to be trunked on both ends.  All the trunk setting does is designate that all VLANs should pass through that port.  (It also specifies the type of VLAN encapsulation, but generally you just take the defaults).

You didn't mention anything about an AP, what model, etc.  Your AP config and wireless controller config will depend on what you want to do with your wireless.

So, my core Catalyst Switch will have one trunk to other swtich for internal VLANs and one trunk to wireless controller for wireless VLAN. Both set of VLANs can be communicated within the switch and each of the trunk link will be responsible for bring its own sets of VLANs into the core switch, correct ?

My wireless controller is 25xx series and AP16xx series. Any comment ?

Are you putting different VLANs on the wireless than on the wired?  Trunks can be configured to pass all VLANs or just certain ones.  It's not really clear what your purpose is for wired vs wireless.  In many organizations the wireless has the same VLAN's as the wired.

Attached the diagram for your reference. Tks
Hi Axishk,

yes you are correct.

Your core switch may have more ports configured in trunk: on each of those ports it will carry the tags from other switches.
In your case, since you have configured vlans on the WLC, you need to connect the wlc port on a trunk port of your switch, so you need to use another trunk port.
Same story for the POE switch, you need to put it in a trunk port of the core switch.
You have no limitations on how many trunk ports you configure on your core switch, you will set just what you need.
Please note that the core switch will have to redirect vlans to the wanted gateway, which will be different for each vlan.

hope this helps

One more check, why PoE need to have trunk link to core switch ?

Is it because of VLANs defined in Wireless controller will be used by APs ?

not really, because the wlc will take care of carried vlans.
I do not know your complete network layout and particularly i do not know if your access points are sitting into a management subnet or if they do not.
So, if your network layout do not need the trunk on the poe switch you can omit it.

hope this helps
