CSR1000V:Troubleshooting - Self-diagnosis Tools

From DocWiki

Jump to: navigation, search

The self-diagnosis tool, accessible by CLI, displays CSR1000V information critical to identifying misconfiguration, in order to help resolve configuration problems.

Based on feedback about common configuration mistakes, the self-diagnosis tool is improved, providing more and more relevant information about the most common configuration issues.

Note: Additional self-diag tools are planned for a future release, to assist in error checking for:

  • Memory configuration
  • Hypervisor compatibility
