Maintenance – Cisco Identity Services Engine (ISE) Patching – 6/18/2026 10 PM

Description

Network Services will apply a software patch to the Cisco Identity Services Engine (ISE) to address a known memory leak.

Expected Impact:
No disruption to campus network access is anticipated during this maintenance. However, ISE is a critical authentication and authorization platform that controls access to network resources, including wireless connectivity, internet access, and other network services. While no outage is expected, there is a small risk that authentication services could be temporarily affected during the maintenance window.

Affected Services:

• Wireless Network Authentication
• Wired Network Authentication (802.1X/MAB)
• Guest Network Access
• Network Resource Authorization
• Internet Access Authentication Services
