Monitor Session Smart Router Deployed as WAN Edge

In monitoring Juniper® Session Smart™ Routers deployed as WAN edge device, you’ll explore the most efficient ways to monitor your WAN edge device in the Juniper Mist™ portal following your initial deployment phase.

WAN Edges

In the Juniper Mist Portal, select WAN Edges > WAN Edges to view basic device monitoring. Notice the Organization name at the top of the GUI, AI-DRIVEN SDWAN AND SASE FULL STACK. This is the largest container and represents your entire organization. Beneath the organization name, you can see your site devices in either a List format or a graphical Topology format. Here, you see Dallas-FullStack is your site, and lab1-dallas is your WAN edge device.

Figure 1: Accessing WAN Edges Page Accessing WAN Edges Page

The List view outlines the following information:

  • Config Success—Percentage of online WAN edges with successful configuration
  • Version Compliance—Percentage of WAN edges that have the same software version per model.
  • WAN Edge Uptime—Percentage of time a WAN edge was up during the past seven days, averaged across all EAN edges.

The Traffic Steering and Application Policy sections show how you use the Session Smart Secure Vector Routing process to create rules for path choice and routing behavior. Note that on the SRX Series deployed as a WAN edge, the Application Policy and Traffic Steering path determine destination zones and must be assigned. The Session Smart router is first and foremost, a router and will use the closest match for the address.

Paths Untagged VLAN (SRX only)

Application Policies are the heart of Juniper’s AI-Driven SD-WAN. Remember that Application Policies are security policies in Juniper WAN Assurance design, where you define which network and users can access which applications, and according to which traffic steering policy. You must create Networks, Applications, and establish Traffic Steering profiles to define an Application Policy. These elements become matching criteria to allow access to or block access from applications or destinations.

Figure 18: Application Policies Application Policies

In the Juniper Mist™ cloud portal, the Networks or Users setting determines the source zone. The Applications and Traffic Steering settings determine the destination zone. Traffic Steering paths determine the destination zone in Juniper Networks® SRX Series Firewalls, so ensure that you assign Traffic Steering profiles to the Application Policies.

Table 13: Application Policies Details
Field Description

Peer Path Statistics

The Session Smart WAN edge devices deployed in Juniper Mist™ WAN Assurance provide insights for liveness and path quality through Session Smart, Secure Vector Routing. The Session Smart use of the Bidirectional Forwarding Detection (BFD) signal on port 1280 checks with the downstream Session Smart Routers for liveness and monitors jitter, latency, loss, and mean opinion score (MOS). This insight works only with our Session Smart devices.

We return to WAN Edge Insights to find the Session Smart Peering metrics on your Mist dashboard. These graphs are at the bottom of the page, with a default view showing the worst three peer connections: jitter, latency, loss, and MOS. Drill down into the data here, using the same time ranges for the WAN Edge Charts. This also means that the graphs are interrelated and cross referenced.

Alerts for Interfaces Status

In Juniper Mist, alerts present network and device issues that are ongoing. You can view alerts on Juniper Mist portal by selecting Monitor > Alerts.

You can set up alerts and email updates for when certain ports on a WAN Edge device go online or offline. To configure alerts for specific ports, you need to label these ports in LAN or WAN settings of WAN Edge device.

To configure the alerts and notifications for specific port, you must:

  • Change the WAN or LAN settings to label the specified ports in WAN Edge template or at device-level configuration page.
    1. In the Juniper Mist cloud portal, select Organization > WAN > WAN Edge Templates and select the WAN or LAN configuration that you want to update. (Or add a new configuration.)

      To configure at the device-level, select WAN Edges on the left-navigation bar and select WAN or LAN configuration of the selected device.

    2. Under Interface, enter the port or ports, and then select Enable “Up/Down Port” Alert Type check-box.
