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. With fabric mode enabled, enter the perfTTmon --show dom command. perfttmon --show dom domainid [n] [wwn | pid] where: domainid n wwn | pid The domain ID of the switch. The number of top talking flows to display, between 1 and 32. The format of the output. The default is wwn. 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 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 Limitations of Top Talker monitors Be aware of the following when using Top Talker monitors: • Top Talker monitors cannot detect transient surges in traffic through a given flow. • You cannot install a Top Talker monitor on a mirrored port. • Top Talker can monitor only 10,000 flows at a time. • Top Talker is not supported on VE_Ports, EX_Ports, and VEX_Ports. • The maximum number of F_Port Top Talker monitors on an ASIC is 8.
