Adding a Top Talker monitor to a port (port mode)
1. Connect to the switch and log in as admin.
2. Enter the perfTTmon
--add command.
perfttmon --add [egress | ingress] [slotnumber/]port
For example, to monitor the incoming traffic on port 7:
perfttmon --add ingress 7
To monitor the outgoing traffic on slot 2, port 4 on an enterprise-class platform:
perfttmon --add egress 2/4
Adding Top Talker monitors on all switches in the fabric (fabric mode)
When fabric mode is enabled, you can no longer install Top Talker monitors on an F_Port unless you
delete fabric mode.
1. Connect to the switch and log in as admin.
2. Remove any EE monitors in the fabric, as described in “Deleting end-to-end monitors” on
page 398. Fabric mode Top Talker monitors and EE 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 EE 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 EE monitors are present on remote switches, the command succeeds; however, on the
remote switches, fabric mode fails and a raslog message is displayed on those switches.
If a new switch joins the fabric, you must run the perfTTmon
--add fabricmode command on
that switch. The Top Talker configuration information is not automatically propagated to the
new switch.
Displaying the top n bandwidth-using flows on a port (port mode)
1. Connect to the switch and log in as admin.
2. Enter the perfTTmon
--show command.
perfttmon --show [slotnumber/]port [n] [wwn | pid]
