Synopsis perfttmon
Port Mode (F_Port):
perfttmon --add egress | ingress [slotnumber/]portnumber
perfttmon --show [slotnumber/]portnumber [number of flows] [wwn| pid]
perfttmon --delete [slotnumber/]portnumber
Fabric Mode:
perfttmon --add fabricmode
perfttmon --show dom domain id [number of flows] [wwn| pid]
perfttmon --delete fabricmode
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:
Top Talker supports two modes, Port Mode and Fabric Mode:
•

Notes This command requires an Advanced Performance Monitor license.
Most platforms supported under Fabric OS v6.0.0 and later support TopTalkers. The Brocade 200E
does not support Top Talkers.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may
be in place. Refer to chapter 1, "Using Fabric OS commands" and Appendix A, "Command
Availability" for details.

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.
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.
