Synopsis perfttmon

perfttmon --add egress | ingress [slot/]port
perfttmon --show [slot/]port [number of flows] [wwn| pid]
perfttmon --delete [slot/]port
Fabric Mode:

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 Talker supports two modes, Port Mode and Fabric Mode:
1. 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 will be displayed in a sorted order
based on the data rate of each flow.
2. 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).
Notes The Top Talker Monitor feature requires a Brocade Advanced Performance Monitor license.
All platforms supported under FOS v6.0 support TopTalkers. This includes Condor and Condor2
ASICs. The GoldenEye ASIC does not support Top Talker.
