Hi,

I want to setup wlc 2504. but i confuse about how to configure the interface and how to connect.

Please see attached picture.

question

1. if i want to connect WLC at core sw, port 24 must be Trunk port?

2. based on the picture attached, can the WLC IP set to 10.154.120.231 (Vlan 120)?

3. should the management IP set to 10.154.120.231 or create new vlan120 and set IP?

4. PoE switch that connect the AP must be configured as Access mode?

5. Can the AP set to VLAN 120?

Thanks.

1. Yes If you need to connect WLC then put in trunk mode.

2. I think yes.

3.If you are setting the wlc vlan to 0 which is untagged, then you need the switchport trunk native vlan xx.( When you configure a VLAN to tag the management interface, WLC will tag all the packets going out of management interface with that VLAN. With native vlan configured in switch port, switch expects frames in native vlan come without any tag 😞 i will recommand to create a vlan and set IP.I will recommand to use tagged the vlan for WLC.

4.Yes AP should be in Access mode if AP are in local mode.

5.yes , its always good to put AP and WLC in same subnet.

By your recomendation, at WLC create VLAN 120 and set IP as 10.154.120.231, is it?

If you're not using 10.154.120.231 with other device. of course you can use it. For me the best way is have the AP's and the WLC on the same vlan, like your picture as well.

Re: wlc 2504 beginner question

Mohd Khairul Nizam — Tue, 25 Feb 2014 17:58:58 GMT

should the IP 10.154.120.231 be configured at management interfaces?

how about other vlan? can it communicate/ping with the WLC?

The WLC is connected to an access vlan 120, so you just need to make sure vlan 120 is being passed on all switches. The wlc port can be an access port, but if you want to use multiple vlans and put users on a different vlan, then you want to trunk it. Best practice is not to use the native vlan and to actually tag the management. You don't need to have vlan120 interface created, because the management already on that vlan. You create dynamic interfaces if you want to place users on a different vlan than 120.

Thanks,

Scott

Yes. Should be. I don't see other vlan's.

Re: wlc 2504 beginner question

Sandeep Choudhary — Tue, 25 Feb 2014 18:27:14 GMT

First thing.

did you created vlan 120 on core swicth ?? if yes then just assign the IP to WLC:10.154.120.231.

If you want to create many wlans..then you have to use trun port for WLC.

Example:

My core: in my examlple wlc and AP are in vlan 80.

WLC ip is 10.99.80.1

Core Switch:

interface Vlan80

ip address 10.99.80.241 255.255.255.0

interface FastEthernet0/18

description *** WLAN Controller, ***

switchport trunk encapsulation dot1q

switchport trunk allowed vlan 80-82

switchport mode trunk

Edge switch:

interface FastEthernet0/21

description *** AP ***

switchport access vlan 80

switchport mode access

If vlan 120 is already exists then just connect WLC to port(trunk- when u need more then 1 vlan to allow) and configure management ip as 10.154.120.231.

What is the ip of vlan 120, it must be diff from wlc management IP.

Hi all,

The problem now is, when i try to tagged the management int to vlan 120, i will lose the connectivity with the WLC.

Why is it?

Re: wlc 2504 beginner question

Sandeep Choudhary — Wed, 26 Feb 2014 07:02:31 GMT

Hi Mohd,

It will be better to configure from the WLC scratch.

Start configuring intial config agaiun and then try.

Hi all,

Thanks for the reply.

Please see attachment

Now i did change the overall IP address. if you all can see that the IP address of WLC and AP were the same as the existing switch. (10.154.101.x/24)

now CORE-->WLC-->Edge SW-->AP can ping each other.

The AP is in Level 2, all device in this floor is using VLAN 120. I can see the wireless signal but unable to retrive the DHCP address. Already assign DHCP server in the management interface.

How can user VLAN 120, connect to the AP?

Post your show WLAN

If you connect a wired laptop to a port in the switch that the AP's are connected to and put that port on Vlan 120, does the laptop get an IP address.

Do you want that user get ip in vlan 120 or ?

It will be better if you use other vlan for user like 121 or any other.

You can use vlan 120 only for manageemnt: its just a suggestion.

Hi Scott,

I don't have connection to the device now, thus i can't show u the result.

I did try to connect my laptop to port 3 at poe switch, i remember i didn't get IP address for vlan 120.

Is it because the port 3 only allow vlan 1 only?

Re: wlc 2504 beginner question

Mohd Khairul Nizam — Wed, 26 Feb 2014 12:46:23 GMT

we have other vlan (130,150) but let say this floor all user is vlan 120, how does when connect to the AP, i get IP address from vlan 120.

right now, i able to connect to the AP but with limited access due to not getting IP address from dhcp server

Re: wlc 2504 beginner question

Mohd Khairul Nizam — Wed, 26 Feb 2014 13:08:09 GMT

i only have 1 WLAN ID using WPA-PSK

Re: wlc 2504 beginner question

Sandeep Choudhary — Wed, 26 Feb 2014 13:29:18 GMT

HI,you hafve vlan 120 on core swicth right ?

did you enter ip helper command under int vlan 120.

Example:

interface Vlan120

ip address 10.xx.120.254 255.255.255.0

ip helper-address 10.xx.21.1 -----> dhcp server IP address

Try this and let us know.
