portCfgISLMode
Enables or disables ISL R_RDY mode on a port.
SYNOPSIS
portcfgislmode
[
slot
/]
port
,
mode
DESCRIPTION
Use this command to enable or disable interswitch link read-ready (ISL R_RDY) mode on a port. Use the
portCfgShow
command to determine whether ISL R_RDY mode is enabled on a port.
In ISL R_RDY mode, the port sends a primitive signal that the port is ready to receive frames. The port
sends an exchange link parameter (ELP) with flow control mode 02. If a port is ISL R_RDY enabled, it
can only receive an ELP with flow control mode 02. A received ELP with flow control mode 01 will
segment the fabric.
This mode cannot detect any inconsistencies in fabric operating mode parameters, such as the PID
format of connected ports. Before enabling ISL R_RDY mode, ensure that all fabric-wide parameters are
consistent for every switch in the fabric.
Use
configShow fabric.ops
to view a complete listing of fabric operating mode parameters on the
switch.
The following E_Port configurations are not applicable to a port configured for ISL R_RDY mode. If
configured, these port configuration parameters are ignored during E_Port initialization:
•
Trunk port
•
VC link init
The
portCfgISLMode
and
portCfgLongDistance
levels LE, LD, or LS only can be enabled at the same
time. Such an ISL uses R_RDY mode of flow control over the long distance link. This feature is not
backward compatible with firmware versions that do not support it.
NOTES
Changes made by
portCfgISLMode
are persistent across switch reboots and power cycles.
This configuration can be cleared but not set on VE/VEX_Ports.
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 Fabric OS port configuration commands are not supported on FCoE ports.
OPERANDS
This command has the following operands:
slot
For bladed systems only, specify the slot number of the port to display, followed by
a slash (/).
port
Specify the port to display, relative to its slot for bladed systems. Use
switchShow
to list valid ports.
mode
Specify 1 to enable ISL R_RDY mode. Specify 0 to disable ISL R_RDY mode.
EXAMPLES
To enable ISL R_RDY mode on a port:
switch:admin>
portcfgislmode 1/3, 1
ISL R_RDY Mode is enabled for port 3. Please make sure
the PID formats are consistent across the entire fabric.
