Brocade Fabric OS Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 506)

If a new switch joins the fabric, you must run the perfTTmon --add fabricmode command on that
switch. The Top Talker monitor configuration information is not automatically propagated to the new
switch.
Displaying the top bandwidth-using flows on a port (port mode)
1. Connect to the switch and log in using an account with admin permissions.
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.
The following example displays the top 5 flows on port 7 in WWN (default) format:
perfttmon --show 7 5
The following example displays the top flows on slot 2, port 4 on a Backbone in PID format:
switch:admin> perfttmon --show 2/4 pid
========================================
Src_PID Dst_PID MB/sec
========================================
0xa90800 0xa05200 6.926
0xa90800 0xa908ef 6.872
Displaying top talking flows for a given domain ID (fabric mode)
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the perfTTmon --show dom command.
perfttmon --show dom domainid [n] [wwn | pid]
Fabric mode must be enabled for this option.
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. The command can display a maximum of 32 flows.
The following example displays the top 5 flows on domain 1 in WWN (default) format:
perfttmon --show dom 1 5
The following example displays the top flows on domain 2 in PID format:
switch:admin> perfttmon --show dom 2 pid
=================================================================
Src_PID Dst_PID MB/sec Potential E-Ports

0x03f600 0x011300 121.748 2/0,2/2,2/3
0x03f600 0x011300 121.748 3/14,3/15
Deleting a Top Talker monitor on a port (port mode)
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the perfTTmon --delete command.
perfttmon --delete [slotnumber/]port
