creditRecovMode If you suspect complete credit loss on a particular virtual channel (VC) on a particular backend port, use the --check option to examine that particular backend port and VC for credit loss. If the command detects complete credit loss, it reports the information. If, in addition, you have enabled link resets on backend ports, this command will perform a link reset on the link in an attempt to recover from the problem. You must explicitly initiate this check and it is a one-time operation. In other words, this command does not continuously monitor for credit loss in the background. Detection of credit loss takes 2 to 7 seconds, after which the results of the operation are displayed. A link reset also generates a RASlog message. For more information on the RASlog messages, refer to the Fabric OS Message Reference. Notes The execution of this command is subject to Virtual Fabric restrictions that may be in place. Refer to "Using Fabric OS Commands" and "Command Availability" for details. This command is supported only on backend ports of 8 Gbps-capable, 16 Gbps-capable, and 32 Gbps-capable blades. The --check option is supported only on modular switches, and only on links between 8 Gbps-capable backend ports or the 8 Gbps-capable to 16 Gbps-capable backend ports. AP blades are not supported. The --fe_crdloss option is supported only on 8 Gbps-capable front-end interswitch link (ISL) ports. Operands This command has the following operands: --cfg Configures credit recovery for backend ports. Use one of the following required recovery options to configure credit recovery: onLrOnly Enables the backend port recovery feature in link reset mode. onLrThresh Enables the backend port recovery feature in link reset threshold mode. off Disables the backend port credit recovery feature. -lrthreshold threshold Specifies the link reset threshold value. The default value is 2. Note that the threshold value set using this option will apply only when the recovery mode is onLrThresh. --fault Configures the blade fault option. Valid values are as follows: edgeblade The edge blade alone is faulted when the link reset threshold is reached. coreblade The core blade alone is faulted when the link reset threshold is reached. edgecoreblade The edge blade is faulted the first two times the link reset threshold value is reached. If the threshold value is reached the third time, the core blade is faulted. 162 Brocade Fabric OS Command Reference 53-1004112-02
