NOTES
Command syntax predating Fabric OS v6.4.0 is no longer supported as of Fabric OS v7.0.0.
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.
The bottleneck detection commands are supported on F_Ports, FL_Ports, E_Ports, and EX_Ports.
The credit recovery commands are supported only on backend ports of Condor, Condor 2, and Condor
3-based blades in the Brocade DCX 8510-8 and DCX 8510-4 chassis.
The -check option is supported only on modular switches, and only on links between Condor 2 core
blades and Condor 2 port blades. AP blades are not supported.
All credit recovery-related options are available with the creditRecovMode command as of Fabric OS
v7.2.0.
OPERANDS
Bottleneck detection commands
The following operands support bottleneck detection:
slot
On bladed systems only, specifies the slot number of the ports to be configured,
followed by a slash (/).
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.
