2 bottleneckMon port_list Specifies one or more ports, relative to the slot on bladed systems. Use switchShow for a listing of valid ports. The --show option allows only a single port or all ports ('*') to be specified with this command, unless it is used without port operand. A port list should be enclosed in double quotation marks and can consist of the following: • A single port, for example, "8" or "5/8" on blades systems. • A port range where beginning and end port are separated by a dash, for example, "8-13" or "5/8-13" on blades systems. A port range cannot span multiple slots. • A set of ports, separated by a space, for example "3 5 7 8"or 5/3 5 7 8 on bladed systems. • A wildcard ('*') indicates all ports. The wildcard must be enclosed in single quotation marks and is not allowed with the --config option. To make switch-wide changes, use --config without a port specifier. --enable Enables bottleneck detection on the switch. This operation is switch-wide and affects all F[L]_Ports and F_Ports. This operation enables bottleneck detection on all eligible ports of a switch, no matter when they become eligible. If you have Virtual Fabrics enabled and you move ports into a bottleneck enabled logical switch from another logical switch, bottleneck detection is enabled upon completion of the move. You can configure optional thresholds and alerts when you enable the feature, or you can change selected parameters later with the --config command. --config Modifies bottleneck detection parameters on specified ports or, when a port list is not specified, on the entire switch. Bottleneck detection must first be enabled before you can fine-tune the configuration with the --config command. The history of bottleneck statistics thus far will not be lost for the specified ports and can be viewed with the --show option. However, alert calculations restart on the specified ports when parameters change. This operation is allowed on excluded ports. The following parameters can be optionally set with the --enable and --config commands. Any numerical parameters not specified with the --config option will retain the current configured values. Whereas, any parameters not specified with the --enable option will assume their default values. -alert Enables both congestion and latency alerts. You can optionally specify either a congestion threshold or a latency threshold, or both. This operand is optional; if omitted, the alerts are disabled. To retain the current alert configuration, you must specify the -alert options for every --config operation. -alert=congestion Enables congestion alerts only. You can optionally specify a congestion threshold for this type of alert. Latency thresholds are not valid. -alert=latency Enables latency alerts only. You can optionally specify a latency threshold for this type of alert. Congestion thresholds are not valid. 82 Fabric OS Command Reference 53-1002746-01
