How to Upgrade Juniper EX JunOS using the Mist Dashboard

In this article I'm going to go through updating JunOS on an EX2300-C switch using the Mist Dashboard.  This functionality is included in the Wired Assurance Subscription.  Once the switch is claimed in your Mist organization (maybe a topic for another post?) the switch will be added to the Switches view and various statistics will be displayed.



Next, check the selection box for the switch(es) to upgrade and click the Upgrade Switches button in the top right. 


A new window will appear with a selection of the version of JunOS to upgrade to.



This pane also includes checkboxes to force a switch reboot once the image is copied.  A reboot can also be performed at later time (for example during a maintenance window) instead of automatically at the end of the JunOS image download.  A recovery snapshot can also be created for easy rollback to the currently running version of JunOS in case of a code related issue.  Finally, the End User License Agreement must be accepted.  Select the target version of JunOS to push to the switch and click the Start Upgrade button.

A small banner will appear at the top of the window stating Upgrading and then the switch view will change to show the upgrade progress.



Selecting the switch will also display the upgrade progress under the Statistics section. 


Navigating to Monitor ->Service Levels->Insights and selecting the switch in the drop down will show the various steps for the switch upgrade.


For this particular upgrade, we can see a storage cleanup was performed, the image was downloaded, and the image was upgraded.  The next step (if selected previously) performs an automatic reboot.  The switch will show offline in the dashboard while the reboot is occurring. 


Once the reboot has completed, the switch will reconnect to the Mist dashboard running the new version of JunOS.  

Mist Wired Assurance has come a LONG way since the Juniper acquisition and I'm very happy to see JunOS updates included in the Mist workflow now.  I look forward to future updates from Juniper/Mist especially around Wired Assurance and EX switch management.

Fix Cisco ISE Messaging Service

Cisco Identity Services Engine 2.6 introduced the concept of the ISE Messaging Service as an encrypted, lightweight protocol to replace syslog communication between the ISE nodes for logging purposes.  The ISE Messaging Services runs over TCP/8671.  In 2.6 Patch 2 and later, the Cisco ISE Messaging Service is enabled by default.   The overall implementation of the ISE Messaging Service has been buggy (but has gotten much better in recent versions) in both new ISE builds and upgrades.  One solution is simply to disable the ISE Messaging Service within Administration > System > Logging.  But then the ISE logging traffic isn't encrypted and the legacy syslog delivery method is not as efficient as the ISE Messaging Service so we will focus the rest of this article on how to identity and fix the ISE Messaging Service. Problem Identification Usually problems with the ISE Messaging Service involve a blank Live Logs page.  You know authentication is working as you have devices/users

ClearPass MPSK per Device Type with Profiling

Image
Multiple Pre-Shared Key or MPSK helps solve for IOT or other endpoint device types that are not 802.1X capable.  The Aruba ClearPass default implementation of MPSK (the configuration created by the wizard) requires manually registering, enrolling, and managing individual PSK keys per endpoint using the ClearPass Guest dashboard.  While the most secure approach, excluding any sort of API based automation, this can obviously be a nightmare to manage and support due to the sheer number of PSKs.  This approach instead delivers a unique PSK per device type (printer, thermostat, etc.) so that each flavor of endpoint would have its own PSK.  If one PSK was compromised, then only those endpoints would need to be manually re-configured.  PSK rotation would also be limited to only those specific device types allowing rotation to take place slowly over several weeks rather than all devices at the same time on the SSID with a traditional single PSK; lessoning the burden on IT staff and minimizing
