Overview of EX Series Switches and the Juniper Mist Cloud

 

This example uses Junos OS Release 18.4R2.7 running on a Juniper Networks EX3400 switch with connections from Juniper access points (APs) driven by Mist AI. All the features you need to set up interoperability between APs with EX Series switches are available in Junos OS Release 18.4R2.7 and later.

We recommend Juniper EX Series switches for interoperability with Juniper access points driven by Mist AI. These devices support Juniper’s Virtual Chassis, which we discuss later in this NCE, and provide Power over Ethernet (PoE) network interfaces and supply 8, 24, or 48 multigigabit ports that comply with IEEE 802.3af standards (such as delivering a regulated 15.4 watts of power).

EX Series switches also support PoE+, which extends normal operation to comply with IEEE 802.3at standards. PoE ports are typically used to connect VoIP telephones, wireless access points, video cameras, point-of-sale devices, and other such devices because they safely deliver power from the interface connection over a copper Ethernet LAN cable, and provide the necessary scale.

We recommend using any of the EX Series switches shown in the following table for use with Juniper access points driven by Mist AI. They meet both the PoE and speed requirements needed for AP deployments, and they support Juniper’s Virtual Chassis.

Cloud-ready, or “greenfield,” switches can be automatically added to the Juniper Mist cloud using the zero-touch provisioning (ZTP) option, and then adopted in the Juniper Mist portal.

“Brownfield” switches, that is, switches being brought into the Juniper Mist cloud from a previous deployment, can also be added to the Juniper Mist cloud.

In either case, the switch needs to connect to a Domain Name System (DNS) server – a Network Time Protocol (NTP) server is also recommended – and it needs to be able to connect to the Juniper Mist cloud over the Internet. If there is a firewall between the cloud and the switch, you need to allow outbound access on TCP port 2200 to the management port of the switch.

We recommend that all switches added to the Juniper Mist cloud be managed exclusively through the Juniper Mist portal, and not from the device’s CLI.

The Juniper Mist portal provides the user interface, and includes AI-driven cloud services and architecture. You can access these through your Juniper Mist account.

The Juniper website provides extensive documentation on both the Junos operating system and the EX Series hardware used in this NCE. Likewise, you can find documentation on Juniper Mist Premium Analytics including configuration details for Juniper APs on mist.com.
