Top Talker monitors

1. Connect to the switch and log in as admin.
2. Remove any end-to-end monitors in the fabric, as described in “Deleting end-to-end monitors”
on page 388. Fabric Mode Top Talker monitors and end-to-end monitors cannot both exist in
the fabric.
3. Enter the perfTTmon -- add fabricmode command.
perfttmon --add fabricmode
The system responds:
Before enabling fabric mode, please remove all EE monitors in the fabric
continue? (yes, y, no, n):
4. Type y at the prompt to continue.
Top Talker monitors are added to E_Ports in the fabric and fabric mode is enabled. Any Top
Talker monitors that were already installed on F_Ports are automatically uninstalled.
If end-to-end monitors are present on the local switch, the command fails with the message:
Cannot install Fabric Mode Top Talker because EE monitor is already present
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.
Displaying the top n bandwidth-using flows on an F_Port
1. Connect to the switch and log in as admin.
2. Enter the perfTTmon -- show command.
perfttmon --show [slotnumber/]port [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, then the command displays the top 8 flows or the total number of flows,
whichever is less.
For example, to display the top 5 flows on port 7 in WWN (default) format:
perfttmon --show 7 5
To display the top flows on slot 2, port 4 on the Brocade 48000, Brocade DCX, or DCX-4S in PID
format:
perfttmon --show 2/4 pid
switch:admin> perfttmon --show 2/4 pid
