Question 1

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.

If you intend to set up wireless mesh at scale, we recommend that you usedevice profiles

Device profiles provide uniformity and scale when onboarding and managing Juniper APs at the organization level.

to save time and simplify management. In such a case, you would create one profile for the base APs and another for the relay APs and then attach the various APs to the correct device profile according to role.

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
  .
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. (Optional, to control failover with multiple mesh links in a site) 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 2

Accepted Answer

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

Question 3

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 4

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 5

Procedure

Accepted Answer

Configure the uplink switch port:
1. Navigate to the switch details page (
  Switches
  >
  Switch Name
  ).
2. Navigate to the Networks and Port Profiles section, and click
  Add Networks
  . Specify a name for the VLAN and specify the VLAN ID. In this example, we’ll create VLANs with VLAN IDs 10, 20, and 30.
  Click the check mark at the upper right of the New Network window to save the configuration.
3. Under Port Profiles, click
  Add Profile
  and create a port profile with the following details:
  - Mode—Trunk
  - Port Network—vlan10
  - Trunk Networks—vlan10, vlan30
  Click the check mark at the upper right of the Port Profile window to save the configuration.
4. Assign the port profile to the ge-0/0/1 port on the uplink switch. Navigate to the Device section, and click
  Add Port Configuration
  . Select the Port ID (ge-0/0/1) and the configuration profile that you created in the previous step.
  Click the check mark at the upper right of the New Port Configuration window to save the configuration.
Designate the base AP in the AP configuration page as shown.
Designate the relay AP in the AP configuration page as shown:
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.

Question 6

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 7

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 8

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

Can I configure a mesh using different AP models?

Accepted Answer

Question 11

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

Accepted Answer

We recommend that you use APs running the same firmware version.

Question 12

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

Yes, it is possible to deploy multiple mesh relay APs on one mesh base AP. We recommend not to exceed 4 mesh relay APs, which we have tested in our environment. A failover from one base AP to another can occur if the signal is weak or if the first base AP goes down.

Question 13

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 14

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.
