perfttmon --show [slotnumber/]portnumber [number of flows] [wwn| pid]
perfttmon --delete [slotnumber/]portnumber

Description Use this command to install the Top Talker monitor. The TopTalker feature provides real-time
information about the top 'n' bandwidth consuming flows from a set of a large number of flows
passing through a specific point in the network (after initial stabilization).
Top Talkers can display between 1 and 32 flows depending on hardware platform. The maximum
flows displayed are as follows:
32 For the Brocade 300, 5100, 5300, and FC8-xx port blades.
16 For the Brocade 4100, 4900, 5000, 7600, and FC4-xx port blades.
4 For the Brocade 7500.
Top Talker supports two modes, Port Mode and Fabric Mode:
• In Port Mode, Top Talker is installed on an F_Port to measure the traffic originating from the
F_Port and flowing to different destinations. The output displays the data in a sorted order
based on the data rate of each flow.
• In Fabric Mode, Top Talker measures the top "n" bandwidth using flows on a given switch. Top
Talker installs only on E_Ports and measures the data rate of all the possible flows in the
fabric. Flow is a pair of communicating FC addresses (SID and DID). Top Talkers in Fabric Mode
and EE monitors are mutually exclusive. EE monitors must be removed from all switches before
enabling fabric mode.
Notes This command requires an Advanced Performance Monitor license.
Most platforms supported under Fabric OS v6.0.0 and later support TopTalkers. This includes
Condor and Condor2 ASICs. The GoldenEye ASIC does not support Top Talker.
