Juniper Mist Alert Types

Juniper Mist™ provides various alerts that you can enable to track ongoing issues.

Infrastructure Alerts

Infrastructure alerts are for events that potentially affect a large number of clients. For example, an unreachable Domain Name System (DNS) or a bad power supply on a switch can affect a large number of clients and a large amount of traffic.

Table 1: Infrastructure Alerts by Severity

Critical Switch Port Up
Note:

If you enable this alert, you also need to update the switch configuration to identify the critical ports. To do this:

  1. In your switch template, under Select Switches Configuration, select the rule for the ports that you want to configure. (Or add a new rule.)

  2. On the Port Config tab, select the port or port range that you want to configure.

  3. In the settings window, select the Enable critical alerts check box.

  4. Repeat these steps for all critical ports.

For more information about port configuration, see the Juniper Mist Wired Assurance Configuration Guide.
Critical WAN Edge Port Up
Note:

If you enable this alert, you also need to update the WAN or LAN configuration to identify the critical ports. To do this:

  1. In your WAN Edge template, select the WAN or LAN configuration that you want to update. (Or add a new configuration.)

  2. Under Interface, enter the port or ports, and then select the Enable critical alerts check box.

  3. Repeat these steps for all critical ports.

For more information about WAN Edges configuration, see the Juniper Mist WAN Assurance Configuration Guide.

Note:

If you enable this alert, you also need to update the switch configuration to identify the critical ports. To do this:

  1. In your switch template, under Select Switches Configuration, select the rule for the ports that you want to configure. (Or add a new rule.)

  2. On the Port Config tab, select the port or port range that you want to configure.

  3. In the settings window, select the Enable critical alerts check box.

  4. Repeat these steps for all critical ports.

For more information about switch configuration, see the Juniper Mist Wired Assurance Configuration Guide.
Critical WAN Edge Port Down
Note:

If you enable this alert, you also need to update the WAN or LAN configuration to identify the critical ports. To do this:

  1. In your WAN Edge template, select the WAN or LAN configuration that you want to update. (Or add a new configuration.)

  2. Under Interface, enter the port or ports, and then select the Enable critical alerts check box.

  3. Repeat these steps for all critical ports.

Marvis Alerts

Marvis alerts are tied into the Marvis Action Dashboard. These alerts are triggered whenever the corresponding Marvis Action is detected in your organization. For example, if an access point (AP) regularly fails health checks, Marvis notices and tracks this event.

Table 2: Marvis Alerts by Severity
Severity Applies To Alert Name
Critical AP AP health check failed
AP insufficient capacity
AP insufficient coverage
Bad cable
Non-compliant
Offline (Marvis)
AP Loop due to Switch Port Flap
AP Loop due to duplicated WLAN paths
Connectivity ARP failure (Marvis)
Authentication failure (Marvis)
DHCP failure (Marvis)
DNS failure (Marvis)
WAN Edge Bad WAN Uplink
Bad cable
Device Problem
MTU mismatch
Negotiation mismatch
VPN Path Down
Switch Bad cable
Missing VLAN
Negotiation mismatch
Port Stuck
Switch STP Loop
Warning Switch Port flap

Security Alerts

Security alerts warn you of activities or events on the network that can cost you in terms of lost data, unauthorized access to the network, or traffic that matches known security threats. Security alerts are raised by repeated events that could dramatically affect network security. For example, if a rogue AP is detected, that represents a potential security problem. If a client connects to a rogue AP, that could be even worse.

Juniper Mist lists all security alerts except those that relate to intrusion detection and prevention (IDP) or URL filtering on the Monitor > Alerts page. You can find IDP and URL filtering events and their severity on the Site > WAN Edge > Secure WAN Edge IDP/URL Events page.
