Q: Can I configure a mesh using different AP models?

Yes. See Supported Models and Firmware for the list of supported AP models.

Question 1

Accepted Answer

Mesh is supported on the models listed below:

AP41/AP41E
AP61/AP61E
AP32/AP32E/AP33
AP34
AP43/AP43E
AP45/AP45E
AP63/AP63E

You can deploy the APs, except the AP34 and AP45/AP45E, in a mesh if the APs run firmware version 0.12.27349 and later. To use the AP34 and AP45/AP45E in a mesh deployment, ensure that the models run firmware 0.14.x or later.

You can use different AP models in the same mesh provided that all the models run the same firmware version.

Question 2

Accepted Answer

Before you set up a mesh, ensure that all the APs have a wired connection to the Mist cloud so that they can receive the configuration. After that, you can disconnect wired links from the APs.

To enable wireless mesh:

Enable mesh networking at the site level:
1. From the left menu of the Juniper Mist portal, select
  Organization
  >
  Site Configuration
  .
  The Site Configuration page appears.
2. Click a site.
3. Scroll down to the Wireless Mesh section of the page and select the
  Enable mesh networking
  check box.
  Wireless Mesh on the Site Configuration Page
  If you enable DFS scanning, the relay AP will scan for the base APs on both DFS and non-DFS channels.
4. Click
  Save
  in the upper-right corner of the page.
Designate the base and relay APs:
1. From the Mist portal, click
  Access Points
  .
  You can also designate base and relay APs in specific device profiles. To simplify the setup of APs in a mesh, you can create separate device profiles for base APs and relay APs. This allows you to easily apply the appropriate profile to different groups of APs.
2. Click an AP.
3. Scroll down to theMeshsection.
4. Select
  Enable mesh networking
  .
5. Choose the role you want for the AP, base or relay:
  - Use as a Mesh Base(AP must have a cable connection to the access switch).
  - Use as a Mesh Relay(AP will transit both client traffic, and management traffic, through a base AP).
  Enabling Mesh in the AP Configuration or Device Profile
6. Click
  Enable Grouping
  and enter a group number (1 through 9) to control which relay APs can failover to a given base AP.
  You can create mesh groups so that a base AP will only accept failovers from relay APs that are members of a given group. Assign a group number (1 through 9) to the relay APs, and then configure the base AP to only accept failover connections from relay APs with that group number.
7. Click
  Save
  in the upper-right corner of the page.
8. After you configure an AP as a relay AP, wait for a few seconds before removing its wired uplink to the switch. Ensure that the relay AP is connected to a power adapter
  The relay AP will now be connected to the base AP. In the Access Points page, you can see which of your APs are set as base and relay. You'll need to enable the Mesh column in the display menu.

If you have any SSIDs broadcasting on the relay AP but not on the base AP, specify the SSID VLAN ID(s) on the Eth0 or Eth1 port of the base AP in the

Ethernet Properties

section.

Here's an example that shows the Eth0 settings on the base AP with VLAN IDs 1, 100, and 101. VLAN 1 is the management VLAN of the AP. You must specify this value in the

Port VLAN ID

field or else the AP will disconnect from the cloud. VLAN 100 and VLAN 101 are for tagged SSIDs, which are broadcasting on the relay AP but not on the base AP.

The AP configuration page for the base and relay APs display the mesh details if the mesh is set up correctly. In the following example, you'll see the details of the relay APs on the base AP configuration page.

Similarly, the configuration page for the relay AP will display the details of the base AP that it connects to.

Question 3

Accepted Answer

In this use case, all the required VLANs in the network are being tagged in the SSIDs.

Question 4

Topology

Accepted Answer

The uplink switch interface ge-0/0/1 has a wired connection to the base AP, which has a wireless mesh link to the Relay AP.

Topology

Question 5

Requirements

Accepted Answer

Uplink switch VLANs (where the base AP gets connected) = 10,20,30
Management VLAN (through which the APs will get the IP address)= 10
Wireless SSID B= tag with VLAN 30
Wireless client should get an IP address from VLAN 30.
Both base and relay APs should get an IP from the management VLAN 10.

Question 6

Procedure

Accepted Answer

Configure the uplink switch port by using the following commands:
set interfaces ge-0/0/1 native-vlan-id 10
set interfaces ge-0/0/1 unit 0 family ethernet-switching interface-mode trunk vlan members [10,30]
SeeAdd or Delete a CLI Configurationfor information about adding CLI configurations to a switch from the Mist portal.
Designate the base AP in the AP configuration page as shown.
AP Settings for Use Case 1 Base AP
Designate the relay AP in the AP configuration page as shown:
AP Settings for Use Case 1 Relay AP
Configure the WLAN for the wireless clients to connect to the base or relay AP. In this example, the clients will obtain an IP address from VLAN 30.
WLAN Settings for Use Case 1

Question 7

Accepted Answer

In this scenario, we need to connect a switch on a relay AP and configure a VLAN on a downlink switch that is not being tagged in the SSIDs.

Question 8

Topology

Accepted Answer

The uplink switch interface ge-0/0/1 has a wired connection to the base AP, which has a wireless mesh link to the relay AP. The relay AP connects to a downlink switch on interface ge-0/0/1. A PC on an access port configured with VLAN 20 connects over interface ge-0/0/2 on the downlink switch.

Topology

The configuration for this use case is similar toUse Case 1, but we also need to enable the Ethernet port configurations in order to pass VLAN 20, which is not in the wireless network.

Question 9

Requirements

Accepted Answer

The Wired PC on the downlink switch should get its IP from VLAN 20.
No wireless SSID is tagged on VLAN 20.
Wireless clients get IPs on VLAN 30.
Switches and APs get IPs on VLAN 10.

Question 10

Procedure

Accepted Answer

Configure the uplink switch ports by using the following commands:
- ge-0/0/1
  - set interfaces ge-0/0/1 native-vlan-id 10
  - set interfaces ge-0/0/1 unit 0 family ethernet-switching interface-mode trunk vlan members [1,10,20,30]
SeeAdd or Delete a CLI Configurationfor information about adding CLI configurations to a switch from the Mist portal.
Configure two ports on the downlink switch port:
- ge-0/0/1
  - set interfaces ge-0/0/1 native-vlan-id 10
  - set interfaces ge-0/0/1 unit 0 family ethernet-switching interface-mode trunk vlan members [1,10,20,30]
- ge-0/0/2
  - set interfaces ge-0/0/2 unit 0 family ethernet-switching interface-mode access vlan member 20
Designate the base AP. Enable mesh, as inUse Case 1. Also enable Ethernet port configurations and enter the settings.
Ethernet Configuration for Use Case 2 Base AP
Designate the relay AP. Enable mesh, as inUse Case 1. Also enable Ethernet port configurations and enter the settings. In this example, you'll see that wired clients connecting to Eth1 on the relay AP will get the IP address on VLAN 10.
Ethernet Configuration for Use Case 2 Relay AP
Configure the WLAN:

Question 11

Can I configure a mesh using different AP models?

Accepted Answer

Yes. SeeSupported Models and Firmwarefor the list of supported AP models.

Question 12

Can I configure a mesh using APs running different firmware versions?

Accepted Answer

We recommend that you use APs running the same firmware version. SeeSupported Models and Firmwarefor information about the supported firmware versions.

Question 13

How many mesh relay APs can be deployed for one mesh base AP?

Accepted Answer

You can deploy up to four mesh relay APs for one base AP.

Question 14

Can I deploy one mesh relay AP for multiple mesh base APs? If yes, how many mesh base APs can be deployed? Will the mesh base APs support failover?

Accepted Answer

A relay AP establishes a mesh link with only one base AP. You can configure up to four base APs to support failover. A failover from one base AP to another can occur if the signal is weak or if the first base AP goes down.

Question 15

Will clients connected to a mesh relay AP have a lower throughput than clients connected to a mesh base AP?

Accepted Answer

If both the mesh and client are on the 5 GHz band, the bandwidth available for the client is shared. Although the bandwidth is shared, it has a minimal impact on the overall throughput. Mist supports only single hop mesh. In multihop mesh, bandwidth is reduced at every mesh hop.

Question 16

What is the recommended distance between a mesh base AP and a mesh relay AP?

Accepted Answer

The distance is dependent on the AP models and antenna types.
