Persistent (Sticky) MAC Learning

Overview Persistent (Sticky) MAC is a Layer 2 port security feature that prevents unauthorized devices from connecting to your network. When this feature is enabled, the switch will observe the incoming source MAC addresses on a configured port and dynamically learn/save this address to memory. You can set the maximum number of MAC addresses learned....

Metrics on the Switches Page

The following are the metrics on the landing page of the Switches Switch-AP affinity PoE Compliance VLANs Version Compliance Switch Uptime   Switch-AP Affinity The Switch-AP Affinity metric displays the weighted percentage of the switches that has more number of APs connected than the configured threshold. By default the Switch-AP Affinity threshold is set to...

Switch Testing Tools

For supported models of Juniper switches which are adopted to your site, we have the ability to perform tests to monitor switch health directly from our Mist dashboard. These are found in the Utilities dropdown menu on the Switches page.  Similar to our AP Testing tools in the AP Details page, the Switch Testing Tools...

Dynamic Port Configuration

Why use Dynamic Port Configuration? Traditionally, ports are configured on a switch based on the device that is connected with a few parameters like VLAN, Trunk/Access etc on every single port basis. Port profiles provide one layer of abstraction to create those profiles with the above parameters once and then re-uses them on ports as...

Template-based Configuration with Device and Port Profile

A key feature of switch management through the Juniper Mist cloud is the ability to use configuration templates and a hierarchical model to group the switches and make bulk updates. Templates provide uniformity and convenience, while the hierarchy (Organization, Network, and Switch) provides both scale and granularity. What templates, and the hierarchical model, means in...

Switch Upgrade

With Mist, we now have the ability to upgrade switches directly from the cloud. Preconditions Ensure stable SSH connectivity from switch to the cloud Ensure enough space on the switch (more details below) Enabling Status Column from the Menu Make sure the status column is enabled in order to see Switch upgrade. The hamburger menu...

Cleanup Procedure for Switch Upgrade

Software Upgrades on EX2300 and EX3400 may fail due to limited storage space available. Should an upgrade fail due to insufficient storage space, we can see the failure reason in the Mist dashboard under Switch Insights:   We can verify available storage space via the Shell/CLI:   Note: the below command can help clear some...

Virtual Chassis

Using Virtual Chassis Juniper recommends using Virtual Chassis (VC). With VC, you can combine multiple EX switches so they act as a single device with regards to the Juniper Mist cloud. This eliminates the risk of loops, the need for legacy redundancy protocols such as spanning tree and VRRP, and the time required for individual...

Virtual Chassis Setup with Mist

Form a Virtual Chassis Onboard (claim / adopt) multiple Ex / QFX switches into MIST (say Mist-ex2300-1, Mist-ex2300-2, Mist-ex2300-3 & Mist-ex2300-4) Navigate to switches tab and ensure all four switches are seen Ensure the Switches are connected to the cloud & configuration by Mist is enabled Select Mist-ex2300-1 and Mist-ex2300-2 and click on More >...

Troubleshooting Switches

If the switch is showing disconnected in the UI but is online locally and reachable then we can try the following steps to troubleshoot further. We will need console access to the switch or SSH access to the switch to check the following: 1. Make sure the EX switch is on the supported version Minimum...
