Synopsis portcfgislmode [[slotnumber/]]portnumber, mode Description Use this command to enable or disable ISL R_RDY mode on a port. If enabling ISL R_RDY mode on a port, make sure the PID format is consistent across the entire fabric. Refer to the configure command for more information on the core PID format. This configuration can be cleared but not set on VE/ VEX_Ports. ISL R_RDY mode sends an ELP with flow control mode 02. If a port is ISL R_RDY mode-enabled, it can only receive ELP with flow control mode 02; ELP with flow control mode 01 segments the fabric. This mode cannot detect any inconsistencies in fabric operating mode parameters, such as the PID format of connected ports. Before using this mode, the fabric administrator must ensure all fabric-wide parameters are consistent for every switch in the fabric. The complete list of fabric operating mode parameters is shown below: Disable Device Probing fabric.ops.mode.fcpProbeDisable Isolated Operation fabric.ops.mode.isolate Long Distance Fabric fabric.ops.mode.longDistance Suppress Class F Traffic fabric.ops.mode.noClassF Switch PID Format fabric.ops.mode.pidFormat Sequence Level Switching fabric.ops.mode.tachyonCompat Unicast-only Operation fabric.ops.mode.unicastOnly Per-frame Route Priority fabric.ops.mode.useCsCtl These parameters can be modified using configure (see configure for more information on the fabric parameters). The following E_Port configurations are not applicable to a port configured for ISL R_RDY mode: • Trunk port • Long distance (L0.5, L1, or L2) • VC link init If configured, these port configuration parameters are ignored during the E_Port initialization. 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. If the PID format for two ISL R_RDY mode ports are not the same, zoning will drop frames. This feature is persistent across reboots and power cycles. Use the portCfgShow command to view whether ISL R_RDY mode is enabled on a port. Note The portCfgISLMode and portCfgLongDistance mode both cannot be enabled at the same time; otherwise, fabric segmentation occurs.
