Acme is having BGP issues with its AOS-CX switch and has asked you to helptroubleshoot...

The question involves troubleshooting BGP issues on an AOS-CX switch, and the task is to identify the appropriate CLI command to begin the troubleshooting process.

Analysis of Options:

Option A (show run | route destination):Incorrect syntax; the show running-config command with a filter is not specific to BGP troubleshooting.

Option B (show debug start):Incorrect; AOS-CX does not use show debug start for initiating debugging.

Option C (show buffer | debug):Incorrect; this is not a valid AOS-CX command for BGP troubleshooting.

Option D:Correct. The show debug destinations command displays the current debug settings, including whether BGP debugging is enabled, which is a critical first step in troubleshooting BGP issues.

Why Option D is Correct:To troubleshoot BGP issues, the first step is to verify if debugging is enabled for BGP events, as this provides detailed logs of session states, messages, and errors. The show debug destinations command on AOS-CX switches shows which debug types (e.g., BGP) are active and where logs are sent (e.g., console, syslog). If BGP debugging is not enabled, the administrator can enable it using debug bgp to capture relevant information, making this the ideal starting point for BGP troubleshooting.

Relevance to Certification Objectives:

Troubleshooting (10%):Involves performing advanced troubleshooting of routing protocols like BGP.

Routing (16%):Includes diagnosing BGP session and configuration issues.
