Using vCLI to troubleshoot the VMkernel

Note: With the release of 5.0, the majority of the legacy esxcfg-*/vicfg-* commands have been migrated over to esxcli. At some point, hopefully not in the distant future, esxcli will be parity complete and the esxcfg-*/vicfg-* commands will be completely deprecated and removed including the esxupdate/vihostupdate utilities.

  • esxcfg-nics
  • vicfg-nics
  • esxcfg-route
  • vicfg-route
  • esxcfg-vmknic
  • vicfg-vmknic
  • esxcfg-vswitch
  • vicfg-vswitch
  • esxcli network nic
  • esxcli network interface
  • esxcli network vswitch
  • esxcli network ip
