Hi Im new to cisco wireless AP.
I need your advice and best way to configure wireless AP. we have 50-70 users in 2 buildings 3 storey. 2 vlans
I have 2 cisco aironet 2602i and 1 1142 aironet.. it is okey if AP-1142 to be access points? and 2 -2602i will be the bridge? can anyone give me configurations?
Thanks

Hi
seems like I am not helping you. so far no ratings :(
Anyway , to be clear please provide this info (represent in X)
vlan 10 - 172..x.x.0/24 (SSID name : xxxx)
vlan 20 - 172.x.x.0/24 (SSID name : xxxx)
vlan x - 172.22.7.0 /24
Note that BVI interface should be un-tagged. So vlan X should be the native vlan of the trunk link. If 172.22.7.0/24 is not suitable for that you need to choose a different subnet for AP management.(in otherwords that subnet cannot be use for AP management IP & given for user under SSID configuration)

Hi Rasika,
I'm not aware the ratings sorry, let me check this so i can rate your answers.
You help a lot rasika your time and efforts is enough and most of all the configurations you send to me. your a bright cisco engineer. :)
Anyway , to be clear please provide this info (represent in X)
vlan 10 - 172..22.7.0/24 (SSID name : TODO_AP1)
vlan 20 - 172.22.10.0/24 (SSID name : TODO_AP1)
vlan x - 172.21.10.0 /24

here are few things to note here.
You cannot assign two vlan for the same SSID in autonomous AP. if you want single SSID, then you have to choose one vlan.
You mentioned you would like to put 172.22.7.34 for the AP which is vlan 10. Since you wan to use this vlan for SSID (wireless users traffic will tag to vlan 10), you cannot use the same vlan for AP management which should be untagged.
You need to have separate vlan/subnet to assign for AP management. You can assign vlan 1 if it is ok & if you have defined gateway for vlan 1 on your switch.
Once we clear on this I can post you the required configuration.
by the way thanks for using the rating system :)

Hi Rasika,
If i can't assign two vlans for the same SSID is there other configurations for this?
what should be the best way to use 2 AP's one SSID in my network with all the vlans and subnets we have?
Here is the configurations of the L3 switch
interface Vlan1
no ip address
!
interface Vlan10
ip address 172.22.10.2 255.255.255.0
ip helper-address 172.22.x.x
!
interface Vlan20
ip address 172.22.7.2 255.255.255.0
ip helper-address 172.22.x.x.
Please advise

What's the point of assigning all current wired user vlans to the wireless network. Typically it is good practice to assign a separate subnet for wireless users rather than mixing wireless users into wired subnets.
If I was you, I will create another vlan (let's say 25) for wireless users & configure a single SSID on all those 3 AP & assign vlan 25. In this way wireless users can move around without changing thier IP/etc (roaming)
Hope that make sense.
What is your exact business requirement of this wireless network ?

Hi Rasika,
Okey i'm good to your suggestions, what should be the configurations for...
*Separate vlans-wireless users
*Single SSID on all those 3 AP & assign vlan 25.
Thanks,

If you ok with that here is what you have to do.
vlan 25 - 172.22.25.0/24
1. Define this L2 vlan on your switch
2. Define SVI for vlan 25 (int vlan 25) & assign 172.22.25.2 /24 (assuming it is the correct gateway IP you want to have)
3. Define DHCP pool for vlan 25 (assume first 20 addresses reserved for APs & SVI). Follow the same configuration options you given for vlan 10,20. So wireless users will get IP in the range of 172.22.25.21 - 172.22.25.254
4. Configure the below configuration on AP-01 & do the same on AP-02 & AP-03 with modified BVI IP & hostname. (I used WLAN password, hostname, SSID given in your config- if you need modify those)
AP-01 : 172.22.25.11/24
AP-02 : 172.22.25.12/24
AP-03 : 172.22.25.13/24
conf t hostname LEDO_AP01 ! dot11 ssid LEDO_WIFI authentication open authentication key-management wpa version 2 guest-mode wpa-psk ascii 7 03035704040E2D5C411E1C17 ! interface Dot11Radio0 encryption mode ciphers aes-ccm ssid LEDO_WIFI no shutdown ! interface Dot11Radio1 channel width 40-above encryption mode ciphers aes-ccm ssid LEDO_WIFI no shutdown ! interface BVI1 ip address 172.22.25.11 255.255.255.0 ! ip default-gateway 172.22.25.2 end write memory !
5. Configure 3 switchports for access vlan 25 & plug those 3 AP. Here is a sample config for a switchport.
interface gx/x description Access Point switchport mode access switchport access vlan 25 spanning-tree portfast
6. Test your wireless connectivity
Give us a try & let us know if you have any further queries.

Hi Rasika,
Thanks for the reply, How can i erase the previous configurations for all the AP's?
I don't want to reset default (by pressing mode button)because start up config will be erase the autonomous which i load from the start up config.
Thanks

Hi
You simply require erase the startup-config & reload without saving.
AP#erase startup-config Erasing the nvram filesystem will remove all configuration files! Continue? [confirm] [OK] Erase of nvram: complete AP#reload System configuration has been modified. Save? [yes/no]: no Proceed with reload? [confirm]
Once reloaded, you can apply the new configurations

Hi Rasika,
its seems working now, please see attached for your comments!

looks good.
If you do "show dot11 association" in AP CLI you will get same detail. Does both 2.4GHz & 5GHz radio enable & clients associate in both bands ?

Very good to see that you get it working.. though it took some time , I think you finally managed it well.
Once everything ok (all 3 AP setup) you can mark this thread as answered.
Thanks for the appreciation & give us a shout for any Cisco wireless queries in future.
