NOTES
This command requires an Advanced Performance Monitor license.
Top Talkers are incompatible with Frame Redirection, and therefore this feature is not supported on the
Brocade Encryption switch for encrypted data traffic.
Top Talkers are not supported on embedded platforms.
Top Talkers are not supported on FCoE ports or ports configured as mirror ports. Top Talkers are not
supported on VE_Ports, EX_Ports, VEX_Ports.
You cannot install a Top Talker and an End-to-End Monitor on the same port. Brocade recommends
against installing a Top Talkers and an End-to-End Monitor on the ports belonging to the same ASIC chip.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
details.
OPERANDS
This command has the following operands:
slot
For bladed systems only, specifies the slot number of the port on which to
configure Top Talkers, followed by a slash (/).
port
Specifies the number of the port on which the Top Talker is to be configured,
relative to its slot for bladed systems. Use switchShow for a list of valid ports.
On 8Gb (Condor 2-based) platforms, port-based Top Talkers are supported only
on F_Ports. On 16Gb (Condor 3-based) platforms, port-based Top Talkers are
supported on both F_Ports and E_Ports.
Port-level Top Talker commands:
--add
Installs the Top Talker monitor on a specified F_Port or E_Port.
egress | ingress
Used with the --add option to specify the direction in which the traffic is monitored
as incoming or outgoing. This operand is required.
-force
Overrides a hardware limitation that does not allow incompatible monitors to
coexist on the same ASIC chip.
--show
Displays the top talking flows on a specified port.
number of top talking flows
Specifies "n" top talking flows. Valid values are between 1 and 32. If a value
greater than 32 is entered, Top Talker displays counters for only 32 flows and a
warning message. This operand is optional; if omitted, the command displays the
top 8 flows.
wwn | pid
Specifies the output display as either WWN or PID format. This operand is
optional. If omitted, the command displays in WWN format.
--delete
Deletes existing Top Talker monitors on the specified F_Ports or E_Ports. You can
specify a single monitor by its port number, or you can specify all monitors. The
-sconfig option deletes all stale monitors.
-all
Deletes all Top Talker monitors from online ports.
