Explanation

When troubleshooting guest portal access issues in Cisco ISE, the most effective tool is a session trace using the endpoint's ID. This is found in the ISE Operations > RADIUS > Live Logs or via Context Visibility. A session trace shows the full authentication and authorization flow-including which policy was matched, what result was returned, and where the process may have failed. This pinpoints whether the issue lies in authentication, authorization policy matching, redirect ACLs, CoA, or portal configuration. Other options like traceroute or posture status checks do not provide the granular ISE policy flow detail needed here.
