Introduction

This document describes the deployment of Point-to-Point mesh links with Ethernet Bridging using Cisco Mobility Express (ME) software.

About Mobility Express

This document uses Cisco 1542 outdoor Access Points. Mesh support on Mobility Express software for indoor and outdoor APs in Flex+Bridge mode was introduced in release 8.10.

The next AP models are supported:

- As an ME Root AP:Cisco AireOS 1542, 1562, 1815s, 3802s APs

- As a Mesh AP: Cisco AireOS 1542, 1562, 1815s, 3802s APs

Mobility Express (ME) is a solution that replaces the Autonomous AP mode and software. It allows a lighter version of AireOS based Wireless LAN Controller (WLC) software to run on the Access Point itself. Both WLC and AP code is stored inside a single partition of the AP memory. A Mobility Express deployment does not require a license file, nor license activation.

Once the device running Mobility Express capable software is powered on, the "AP part"  first boots up. A few minutes later, the controller part also initializes. Once a console session is established, an ME capable device shows the WLC prompt. In order to enter the underlying AP shell, a command apciscoshell can be used:

(Cisco Controller) >apciscoshell

!!Warning!!: You are entering ap shell. This stops you from establishing new telnet/SSH/Web sessions to controller.

Also the exsisting sessions is suspended till you exit the ap shell.

To exit the ap shell, use 'logout'

Prerequisites

Components Used

- 2x 1542D-E Access Points

- 2x 3560-CX Cisco Switches

- 2x Laptops

- 1x Console Cable

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Network Diagram

All the devices in this network is located inside the 192.168.1.0/24 subnet. The Mobility Express AP (controller) has its management interface untagged, while the native VLAN on all ports is VLAN 39. AP 1542-1 takes the role of a controller and Root Access Point (RAP), while AP 1542-2 takes the role of Mesh Access Point (MAP). This table contains the IP addresses of all devices in the network:

Note: Tagging the management interface can cause issues with the AP joining the internal WLC process. If you decide to tag the management interface, ensure that the wired infrastructure part is configured accordingly.

Factory Reset of the APs

It is recommended to perform a factory reset of the APs before starting a new deployment. This can be done by pressing the mode/reset button on the AP, plugging the power in and continuing to hold it for more than 20 seconds. This ensures that all previous configuration has been wiped. The AP is accessible via a console connection with default username of Cisco and password of Cisco (case sensitive).

A factory reset does not necessarily move an AP back to lightweight mode if it is already running in Mobility Express. An important step is to identify if your APs are running a lightweight image or a Mobility express image.

If your AP is lightweight, you can convert it to Mobility Express by downloading the mobility express code. If the AP is already in mobility express mode, you have to follow the upgrade process in the GUI of the access point/controller to change the software version.

Example of a show version from AP running lightweight image :

cisco AIR-AP1562I-E-K9 ARMv7 Processor rev 1 (v7l) with 1028616/605344K bytes of memory. Processor board ID FCZ2150Z099 AP Running Image : 8.5.151.0 Primary Boot Image : 8.5.151.0 Backup Boot Image : 0.0.0.0 1 Gigabit Ethernet interfaces 2 802.11 Radios Radio Driver version : 9.0.5.5-W8964 Radio FW version : 9.1.8.1 NSS FW version : 2.4.26

This is an example of AP already running in Mobility Express software :

AP#show version . .. AP Running Image : 8.10.185.0 Primary Boot Image : 8.10.185.0 Backup Boot Image : 8.10.185.0 . .. . AP Image type : MOBILITY EXPRESS IMAGE AP Configuration : MOBILITY EXPRESS CAPABLE

Downloading Lightweight capwap Image to 1542-2 (MAP)

Laptop 1 is used as a TFTP server. AP 1542-2 can be initially connected to Switch 1 Gig 0/8 port just so that the upgrade can be performed. On software.cisco.com, under 1542 lightweight images, download 15.3.3-JJ1 (full name ap1g5-k9w8-tar.153-3.JK9.tar) which corresponds to the 8.10.185 release image. The latest lightweight AP image always corresponds to the latest ME version.

Place the image in the TFTP root folder. Connect the console cable, login using the default credentials (username is Cisco and password is also Cisco). Assign the IP address to the AP and perform the upgrade using these commands:

#capwap ap ip 192.168.1.202 255.255.255.0 192.168.1.1

#archive download-sw /reload tftp://192.168.1.100/ap1g5-k9w8-tar.153-3.JK9.tar

AP performs the upgrade and then reboot. Confirm that the upgrade has been successful using show version command:

MAP#show version

.

..

AP Running Image     : 8.10.185.0

Primary Boot Image   : 8.10.185.0

Backup Boot Image    : 8.8.125.0

AP is unplugged from Switch 1 and plugged back into the Switch 2.

Note: By upgrading the image of the MAP manually, we are avoiding the image upgrade process taking place over-the-air once the mesh link is established.

Downloading Mobility Express-Capable Image to AP 1542-1 (RAP)

Under Mobility Express 8.10.105 releases for 1542 AP, we can see 2 available files: .tar and .zip. Download the .tar file:

Download the .tar file

Unlike a physical WLC, ME Access Points do not have enough flash memory to store all the AP images, so having a TFTP server accessible at all times is necessary if you want to join further APs to your Mobility Express access point. This step is not necessary if we manually upgrade the APs like in this example.

In order to perform the upgrade, connect the console to the AP 1542-1, assign an IP address to it and perform the upgrade of the image:

#capwap ap ip 192.168.1.201 255.255.255.0 192.168.1.1

#ap-type mobility-express tftp://192.16.1.100/AIR-AP1540-K9-ME-8-10-185.tar

Once the upgrade is finished, the AP reboots. Soon after the AP is up, the controller part starts booting up as well. We soon see the zero-day provisioning SSID "CiscoAirProvision" being broadcast.

If you ar eon console, you can see a CLI wizard but do not configure the AP that way. The over-the-air GUI wizard is the way to go.

Zero-day SSID Provisioning

Connect to the "CiscoAirProvision" SSID broadcast by the AP using the password password. The laptop gets an IP address from the subnet 192.168.1.0/24.

In case you do not see the SSID being broadcast, it is still possible that the AP is in "Mobility express CAPABLE" but not running as mobility express. You then would have to connect to the AP CLI and enter ap type mobility-express and the AP reboots and broadcasts the provisioning SSID.

It is also possible to convert the AP between local mode and mesh mode using capwap ap mode local/flex-bridge if you need to, during this setup.

Open the address http://192.168.1.1 in a web browser. This page redirects to the initial configuration wizard. Create an admin account on the controller by specifying admin username and password and then clickStart.

In the next step set up the controller by specifying the values.

Field Name

Description

System Name

Enter the system name for the Mobility Express AP. Example: MobilityExpress-WLC

Country

Choose a country from the drop-down list.

Date & Time

Choose the current date and time.

Note: The wizard attempts to import the clock information (date and time) from the computer using JavaScript. It is highly recommended that you confirm the clock settings before continuing. The access points depend on clock settings to join the WLC.

Timezone

Choose the current time zone.

NTP Server

Enter the NTP server details.

Management IP

Enter the Management IP address. NOTE : It must be different from the IP assigned to the access point ! In this example, while the AP got the .201 IP, we assign .200 in the configuration wizard. both is used.

Subnet Mask

Enter the subnet mask address.

Default Gateway

Enter the default gateway.

In this setup, the DHCP server is running on Switch 1, so there is no need to enable it on the ME WLC. Slide the Mesh option to Enable and click Next.

In the next step create the wireless network by specifying these fields:

Field Name

Description

Network Name

Enter the network name.

Security

Choose the WPA2 Personal security type from the drop-down list.

Passphrase

Specify the Pre-Shared Key (PSK).

Confirm passphrase

Re-enter and confirm the pass phrase.

This network can be disabled in later stage.

In the Advanced Settings tab, leave the RF Parameter Optimization slider disabled and click Next:

Once the settings are confirmed, the WLC reboots:

Additional Mesh Configuration

Before establishing the mesh link, MAP needs to be converted to flex-bridge mode. The RAP is already in flex-bridge mode if the mesh option has been enabled during initial config. This can be done from the CLI:

MAP# capwap ap mode flex-bridge

MAP#[*11/05/2019 18:26:28.1599] AP Rebooting: Reset Reason - AP mode changed

In order for MAP top join the ME controller, it needs to be authorized. On MAP, find the mac address of its ethernet interface:

MAP#show interfaces wired 0

wired0    Link encap:Ethernet  HWaddr 00:EE:AB:83:D3:20

inet addr:192.168.1.202  Bcast:192.168.1.255  Mask:255.255.255.0

UP BROADCAST RUNNING PROMISC MULTICAST  MTU:1500  Metric:1

RX packets:183 errors:0 dropped:11 overruns:0 frame:0

TX packets:192 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:80

RX bytes:19362 (18.9 KiB)  TX bytes:22536 (22.0 KiB)

From laptop 1, access the ME controller web interface via https://192.168.1.200. After expert mode has been enabled (top right corner), a mesh tab appears under Wireless settings. Under mac filtering, add the ethernet MAC address of the MAP:

Note: Any subsequent AP in bridge or flex-bridge mode that is being joined to ME WLC needs to be authorized as well

After setting this up, a mesh link is established. In order for wired client behind the MAP to pass the traffic over the mesh link, Ethernet Bridging needs to be enabled on the MAP under Wireless Settings > Access Points > MAP > Mesh:

If the mesh link is using a 5GHz band, it can be affected by radar signatures. Once the RAP detects a radar event, it switches to another channel. It is recommended to enable the Channel Change Notification so RAP notifies the MAP that the channel is switched. This significantly lowers the convergence time as MAP does not have to scan all the available channels:

Verify

We can verify that the MAP has joined by running show mesh ap summary command:

(Cisco Controller) >show mesh ap summary

In order to test if the link is passing through the traffic, Cisco tries to ping from Laptop 1 to Laptop 2:

VAPEROVI:~ vaperovi$ ping 192.168.1.101

PING192.168.1.101 (192.168.1.101): 56 data bytes

64 bytes from192.168.1.101: icmp_seq=2 ttl=64 time=2.875 ms

Note: You are able to ping MAP or RAP IP address only once the mesh link has been established.

Troubleshooting

On the MAP/RAP:

- debug mesh events

On ME WLC:

- debug capwap events enable

- debug capwap errors enable

- debug mesh events enable

Tips, Tricks and Common Mistakes

- By upgrading the MAP and RAP to the same image version over the wire, we are avoiding image download going over the air (which can be problematic in "dirty" RF environments).

- Increasing the channel width of the 5GHz backhaul link can lead to lower SNR and false radar detections (mainly on 80MHz and 160 MHz).

- Mesh link connectivity must not be tested by pinging MAP or RAP. They is not pingable once the mesh link comes up.

- It is highly recommended to test out the setup in a controlled environment before deploying it on site.

- If APs with external antennas are being used, make sure to consult the deployment guide to check which antennas are compatible and which port they must be plugged in.

- In order to bridge the traffic from different VLANs over the mesh link, VLAN Transparent feature needs to be disabled.

- Consider having a syslog server local to the APs, as it can provide debug information otherwise only available with a console connection.
