Why each option
To obtain detailed troubleshooting information about an authentication failure on a specific port, the `show authentication sessions interface <interface_id> details` command is required.
`show authentication sessions` provides a summary of all active authentication sessions but lacks the detailed information necessary for in-depth troubleshooting of a specific failure.
The `show authentication sessions interface Gi1/0/1 details` command provides a comprehensive view of the authentication session on the specified interface, including authentication method, status, authorization policy hit, and other granular details essential for diagnosing authentication problems. This command provides more in-depth information than a basic summary.
