perfTTmon 2 NOTES OPERANDS Because of a hardware limitation on Brocade devices, the following types of monitors cannot coexist on the same ASIC chip: • If an end-to-end monitor is installed on a port in a given ASIC, you cannot install an ingress or egress Top Talker monitor on another port on the same ASIC. • If an ingress Top Talker monitor is installed on a port in a given ASIC, you cannot install an egress Top Talker monitor or an end-to-end monitor on another port of the same ASIC. • If an egress Top Talker monitor is installed on a port in a given ASIC, you cannot install an ingress Top Talker monitor or an end-to-end monitor on another port of the same ASIC. You can use the -force option to override these limitations and install incompatible monitors on ports of the same ASIC. However, if you choose to do so, be aware that the statistics will not be accurate. 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. 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. Fabric OS Command Reference 615 53-1002746-01
