Autonomous AP as WGB (Multiple VLAN)

In this post we will learn how to configure an autonomous AP as WGB with Multiple VLAN.

How to setup Root AP and WGB: Check this post

***I don’t have extra switch so I will force WGB to connect to clicnet in vlan 12.

***In my post WGB and Root AP both are on vlan 11(Native) and Client will get the IP in vlan 12.

*** Link between RootAP and switch is trunk.

Switch Config:

 Int fa0/24
 Switchport trunk encapsulation dot1q
 Switchport trunk native vlan 11
 Switchport trunk allowed vlan 11,12
 Switchport mode trunk

 WGB_2vlan

Remembering Points:

  1. The AP to which a WGB associates can treat the WGB as an infrastructure device or as a normal client. By default, AP treats WGB as client devices.
  1. If WGB is an infrastructure client, it can associate to an infrastructure SSID. Infrastructure SSIDs are used to authenticate Bridges, Repeaters…Etc. A WGB in by default is a “client”, not an “infrastructure client” and therefore cannot associate to an infrastructure SSID.

Use of Infrastructure-Client Command:

  1. Used for Reliable Multicast
  2. To make WGB as Infrastructure-Client so that WGB can associate to Infrastructure-SSID.

In my example WGB is connected root AP via RSCCIEW WLAN interface.

WGB authentication with LEAP-WPA2.

Normally its not recommended by cisco to use multiple vlan on WGB 🙂

Autonomous AP as WGB (Single VLAN)

In this post we will learn how to configure an autonomous AP as WGB.

WGB can provide the wired connection to the devices which don’t have wireless adaptor so that device can directly connect to WGB Ethernet port to access the wireless network.

It can provide wireless connectivity to wired clients that are connected by Ethernet to the work-group bridge access point.00

WGB connect to root AP as a client through the wireless interface.

Basic Info:

  • Infrastructure SSID configuration not required
  • By default when the WGB associates with the root bridge, all the wired clients + the WGB are shown as normal clients.
  • A WGB can only pass one VLAN between the WGB and the root bridge(As Cisco recommend but it can also pass multiple)
  • Always use bridge-group 1 for the link between the root and WGB.
  • But if we use WGB multicast infrastructure mode on the WGB, we need to add infrastructure-client on the root AP side.
  • A WGB in standard mode is by default a “client”, not an “infrastructure client” and therefore cannot associate to an infrastructure SSID.
  • WGB is a mobile
  • Root AP can allow max 20WGB.(This must be test out)

 My Topology:

WGB_Vlan1

Remembering Points:

  1. The AP to which a WGB associates can treat the WGB as an infrastructure device or as a normal client. By default, AP treats WGB as client devices.
  1. If WGB is an infrastructure client, it can associate to an infrastructure SSID. Infrastructure SSIDs are used to authenticate Bridges, Repeaters…Etc. A WGB in by default is a “client”, not an “infrastructure client” and therefore cannot associate to an infrastructure SSID.

Use of Infrastructure-Client Command:

Autonomous AP as Wireless Bridge with Multiple VLAN

In last post we learned about how to setup a root and non-root bridge. In this post we will see the configuration for multiple VLAN on Root, Non-Root Bridge for wireless clients.

Topology is same as it was in last post: Autonomous AP as Wireless Bridge

Again here I will use WPA2-PSK to authenticate both WLAN. One WLAN for Root-AP to Wireless-Bridge communication and other WLAN for clients to authenticate.

We will not waste our much time on theory, let’s directly jump to configuration:

Autonomous AP as Wireless Bridge

In this post we will learn how to configure AP as wireless bridge. I tried to find the documents on cisco but they are very limited.

Let’s learn something about Wireless Bridges.

Here is my Topology:

Wirelessbridge1

I have two 1240 model APs.

Root-AP: 10.35.80.110

Wireless-Bridge: 10.35.80.111

A wireless bridge is a Layer 2 device; it connects two or more LANs, which can be in different buildings, through the wireless interface. Wireless bridges provide higher data rates and superior throughput for data-intensive and line of sight applications. Wireless bridges eliminate the need for expensive leased lines and fiber-optic cables and mostly used to connect two sites where either WAN line is not available or available but expensive.

In this post I will create a WLAN “RSCCIEW” to connect Root-AP & Wireless-Bridge.

Remembering Points:

  • It will always connect to Root-AP via Native VLAN.
  • It can support multiple VLAN. (Not like Repeater).

Let’s start with configuration:

Basic Root-AP/Wireless-Bridge Configuration with WPA2 encryption/single SSID.

Root AP:

Once completion of configuration, we will these logs:

*** If we want to authenticate Wireless-Bridge with LEAP(How to Authenticate with LEAP) or EAP-FAST(How to Authenticate with LEAP) then we have to use the same method as we did for Repeaters. Check my old post to use EAPFAST or LEAP to authenticate Repeater, Wireless Bridge, WGB, and Universal WGB.

In the next post we will learn how to Authenticate Repeater via EAP-FAST.

Autonomous AP as Repeater with WPA2

In this post we will learn how to configure a repeater to extend our wireless coverage.

To extend or increase the range of our WLAN, we can add a repeater AP to the network. This repeater AP will not physically connected to the WLAN, but is instead added to radio range of the wired connected Access Point and the clients that access the WLAN.

***AP has two radios, only one can be used as a repeater. We must configure the other as a root radio.

***Repeater only can connect to root AP in Autonomous mode.

Here is my test lab setup:

Client………..Repeater-AP…………Root-AP——–Switch

Repeater_setup

When we configure an AP as a repeater, the access point’s Ethernet port does not forward traffic.

*** After our AP is configured as a repeater, it shuts down its Ethernet connection. Any devices connected to the Ethernet port are disconnected from the AP.

Of-course we can configure multiple APs as repeaters, but throughput decreases as additional APs are added to the chain, because each repeater must receive/retransmit the packet on the same channel. Because of this, throughput is cut in half for each repeater added.

A repeater AP connects to the root AP which has the best connectivity. But we can specify the AP to which the repeater associates. Setting up a static, specific association between a repeater and a root access point improves repeater performance.

Remembering Points:

  • It’s best to use repeaters to serve clients that do not require high throughput.
  • Cisco AP repeaters work best when clients are Cisco devices. Problems occur when third-party devices try to associate with repeater APs.
  • Ensure the data rates configured on the repeater AP match the data rates of the parent AP.
  • We can’t configure multiple VLANs on repeater access points. Repeater access points support only native VLAN.
  • If Repeater is connected to root AP, which has many BSSIDs and we are adding/deleting SSID on root AP that might change the parent mac address. So if we are making some changes on root AP then we must again check the connectivity between root AP and repeater after modification.

Steps to Configure the AP as Repeater:

  1. Enable Aironet extensions on both the parent and repeater APs. By default, these extensions are enabled. (Aironet extensions, which are enabled by default, improve the access point’s ability to understand the capabilities of Cisco Aironet client devices associated with the access point.)
  2. Setup the SSID under specific Radio {0 or 1}
  3. Assigns the SSID as an infrastructure SSID. This is the SSID the repeater uses to associate to the root AP.

The infrastructure SSID must be assigned to the native VLAN. If more than one VLAN is created on an AP, an infrastructure SSID cannot be assigned to a non-native VLAN. The following message appears when the infrastructure SSID is configured on non-native VLAN:

ap(config-ssid)#infrastructure-ssid optional
 Dot11Radio0: SSID Test must be configured as native-vlan before enabling infrastructure-ssid
ap(config-ssid)#

*** The ”optional” argument allows regular clients to associate as well.

  1. Establishes this AP’s role as a repeater.

By using this command: station-role repeater

  1. We can enter MAC addresses for up to four parents. If the repeater fails to associate to the first parent, it moves to the next on the list. We can enter a timeout, which establishes how long the repeater tries to associate to a parent before it moves to the next.

Once completion of configuration, we will these logs:

*Oct 6 09:23:28.003: %DOT11-6-ASSOC: Interface Dot11Radio0, Station Repeater-AP 2894.0fa8.a594 Associated KEY_MGMT[WPAv2 PSK]

Now let’s connect a client to repeater AP and see its Status:

Root-AP#sh dot11 ass
 802.11 Client Stations on Dot11Radio0:
 SSID [RSCCIEW] :

Root-AP#

If we want fix the repeater to associate to specific root Aps, we can use “Parent <1-4>mac-address [timeout]” command under radio interface of repeater. Maximum 4 parent’s mac addresses are allowed. In our case we have only one Root-AP.

Also we can enter a timeout value in seconds that determines how long the repeater attempts to associate to a parent access point before trying the next parent in the list. Timeout value varies from 0 to 65535 seconds.

Here is the command:

Repeater-AP#Conf t
Repeater-AP(config)#Parent 1 mac 003a.9914.1370

In next post we will see the Repeater authentication via LEAP.
