2 perfTTmon perfTTmon Installs the Top Talker monitor in the specified mode. Synopsis perfttmon Port Mode (F_Port): perfttmon --add egress | ingress [slot/]port perfttmon --show [slot/]port [number_of_flows] [wwn| pid] perfttmon --delete [slot/]port 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: 32 For the Brocade 300, 5100, 5300, 8000 (FC Ports only) 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. Top Talkers are incompatible with Frame Redirection, and therefore this feature is not supported on the Brocade Encryption switch for encrypted data traffic. Top Talkers are not supported on embedded platforms. Top Talkers are not supported on VE_Ports, EX_Ports, VEX_Ports, FCoE ports or ports configured as mirror ports. 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. 594 Fabric OS Command Reference 53-1001764-02
