Usage Each fabric, cluster, standalone switch, or virtual network can track application flow statistics. This command displays information about vflows configured on the switch.
Examples To display vFlow information, use the following command:
CLI (network-admin@switch) > vflow-show
switch name scope type burst-size precedence from-tunnel-decap transparency enable table-name
