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 install
Top Talkers, followed by a slash (/).
port
Specifies the number of the port on which the Top Talker is to be installed, relative
to its slot for bladed systems. Use switchShow for a list of valid ports.
On 8G (Condor 2-based) platforms, port-based Top Talkers are supported only on
F_Ports. On 16G (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.
--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 a specified F_Port or E_Port. 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.
-sconfig
Deletes all stale Top Talker entries from the configuration file. A Top Talker monitor
is considered stale when it can no longer monitor due to a configuration change,
but it still exists in the persistent configuration. For example, a Top Talker
becomes stale when a port configured for Top Talker goes offline. The -sconfig
option provides a mechanism for deleting the Top Talker monitors, as well as the
configuration keys of all ports on Condor 2-based platforms, and of all offline ports
belonging to a port blade that has been removed from the chassis. When a stale
Top Talker entry is still present in the configuration file, you cannot enable FC
routing services.
