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...

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 burde...

Aruba AOS-CX Switch 802.1X/MAB Template for ClearPass, ISE, FortiAuthenticator, etc

Below is a template for Aruba AOS-CX Switches for 802.1X and MAB. This template can be used with any standards-based RADIUS server such as Aruba ClearPass, Cisco Identity Services Engine, Fortinet FortiAuthenticator, FortiNAC, FreeRADIUS, etc. This configuration is just basic 802.1X and MAC Address Bypass, it does not cover Downloadable User Roles (DUR) or other advanced Aruba segmentation features.  The various sections of the configuration are explained prior to each as a comment denoted by !. This configuration should be valid for any version of AOS-CX and has practically been tested with both Cisco ISE and Aruba ClearPass. !Define the RADIUS servers. This can be a ClearPass VIP, a load-balancer, or the actual RADIUS servers. Replace the x.x.x.x with your RADIUS server IPs. radius-server host x.x.x.x key plain-text SuperSecureKey! radius-server host x.x.x.x key plain-text SuperSecureKey! !Place the RADIUS servers inside a AAA group.
