Cisco 2100 wireless controller question

stillanoobin2020 — Sun, 04 Jul 2021 03:57:19 GMT

I recently got a new Cisco 2100 series wireless controller.

I need to set it up in a multi vlan environment.

Having it connecting and registering WAP that are connected to my switches is not a big issue.

What i'm having trouble figuring out is how to set it up so that i can make use of its 2 POE ports.

What i'm trying to figure out is what VLAN those ports will be in when i connect the WAP to it.

I can set VLAN tags to ports but only if i create new interfaces, and i dont think i would have to create a new interface for each WAP i need to connect.

I hope i'm making myself clear on this if not please ask and i will try to clarify.

Don't confuse "SSID's" "interfaces" and "ports" on your wireless controller.

They're very different, but depend on one another.

First, configure your ports (up/down, duplex, etc) at Controller / Ports

Then configure an interface on the controller and then assign that interface to a physical port at Controller Interfaces

Interface configuration is where you configure vlan ID, IP address, mask, gateway, etc.

SSID creation - Go to WLANs and add or change an ssid. Point it to an interface.

The interface/port marriage takes care of the rest.

Ok so i was not clear enough.

lets say that in my environment i have 2 vlans 10 and 100

On my switch port i can configure it a a trunk and allow vlans 10 and 100

on the wireless controller i create 2 interfaces 10 and 100

interface 10 is connected to port 1, with ip address 10.10.10.10 255.255.255.0 and assigned to vlan 10, i can then configure an SSID to that interface

interface 100 is connected to port 1, with ip address 10.100.100.100 255.255.255.0 and assigned to vlan 100, i can then configure an SSID to that interface

This puts port 1 on the controller in trunk mode and allows communications with the rest of the network.

On a switch i can configure the WAP ports to either vlan so they get an ip address from dhcp and bind to the controller.

However i want to use POE for 2 of my access point, and unforutnatley i dont have POE switches.

SO i want to meke use of the 2 POE ports on the wireless controller, so i plug a WAP in port 7.

Which VLAN is the device in?
