Deleting The Fabric Mode Top Talker Monitors; Displaying Top Talking Flows For A Given Domain Id (Fabric Mode); Limitations Of Top Talker Monitors - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

If end-to-end monitors are present on remote switches running Fabric OS 6.1.0 or later, the command
succeeds; however, on the remote switches, 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.
If a new switch joins the fabric, you must run the perfTTmon --add fabricmode command on the
new switch. The Top Talker configuration information is not automatically propagated to the new switch.

Deleting the fabric mode Top Talker monitors

1. Connect to the switch and log in as admin.
2. Enter the perfTTmon
perfttmon --delete fabricmode
All Top Talker monitors are deleted.

Displaying top talking flows for a given domain ID (fabric mode)

1. Connect to the switch and log in as admin.
2. With fabric mode enabled, enter the perfTTmon
perfttmon --show dom domainid [n] [wwn | pid]
where:
domainid
n
wwn | pid
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 eight flows or the total number of flows, whichever is less. The
command can display a maximum of 32 flows.
For example, to display the top 5 flows on for domain 1 in WWN (default) format:
perfttmon --show dom 1 5
To display the top flows on domain 2 in PID format:
perfttmon --show dom 2 pid
The following is a sample command and output.
switch:admin> perfttmon --show dom 2 pid

• Top Talker can monitor only 10,000 flows at a time.
• Top Talker is not supported on VE_Ports, EX_Ports, and VEX_Ports.
