Commands and Parameters Applicable to vFlow Traffic


The vFlow feature includes several commands and keyword parameters to configure and monitor various vFlow actions. Some of the important commands and parameters are explained in this section.


  • To create a new vFlow object, use the command:


CLI (network-admin@switch-1) > vflow-create name <vflow-name> scope [local|fabric] {parameters}


  • To modify an existing vFlow object,


CLI (network-admin@switch-1) > vflow-modify name <vflow-name> {parameters}


  • To delete an existing vFlow object,


CLI (network-admin@switch-1) > vflow-delete name <vflow-name> 


  • To display existing vFloiw objects,


CLI (network-admin@switch-1) > vflow-show {parameters}
