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 end-to-end monitors in the fabric, as described in “Deleting end-to-end monitors”
on page 390. 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.
Deleting the fabric mode Top Talker monitors
1. Connect to the switch and log in as admin.
2. Enter the perfTTmon
--delete fabricmode command.
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. Enter the perfTTmon
--show dom command.
perfttmon --show dom domainid [n] [wwn | pid]
Fabric mode must be enabled for this option.
