Using information resources

The following information is helpful for incident investigation and resolution when you contact your device-support provider:

• A network diagram and topology information
• A record of the steps and events leading to the incident
• Lists of applications, management agents, and scripts running at the time of the incident
• supportSave files
• Output from the show media command if the issue is related to SFP transceivers
• Outputs from any commands run while attempting to troubleshoot the problem yourself
• Any network traces captured using Wireshark software or other network analyzer.
• Terminal Access Controller Access-Control System (TACACS) server version if the issue is related to TACACS.
