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.
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.
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.
