Enter y at the prompt to continue. Top Talker monitors are added to all E_Ports in the fabric and fabric mode is enabled. Any Top Talker monitors that were already installed on F_Ports are automatically uninstalled. If end-to-end monitors are present on the local switch, the command fails with the message: Cannot install Fabric Mode Top Talker because EE monitor is already present. If end-to-end monitors are present on remote switches running Fabric OS 6.1.0 or later, the command succeeds. On the remote switches, however, fabric mode fails and a raslog message is displayed on those switches. If end-to-end monitors are present on remote switches running Fabric OS 6.0.x, the command succeeds.

The output is sorted based on the data rate of each flow. If you do not specify the number of flows to display, the command displays the top 8 flows or the total number of flows, whichever is less. The command can display a maximum of 32 flows.
