portCfgEportCredits portCfgEportCredits Configures normal distance E_Port buffer allocation. Synopsis portcfgeportcredits --enable [slot/]port credits portcfgeportcredits --disable [slot/]port portcfgeportcredits --show [slot/]port portcfgeportcredits --help Description Use this command to change the default credit allocation for a normal distance E_Port or EX_Port by allocating the specified number of credits to the port. When port credit allocation is enabled, the number of credits specified overrides the default E_Port credit allocation; that is, a new credit model is constructed based on the user-configured credits value. When the configuration is disabled, the default credit allocation (default credit model) is restored. Only a normal distance E_Port and EX_Port can utilize the new credit model constructed by this command, and the allocated credits are reserved only for that port. ICL ports are supported and are used in conjunction with 2 km ICL QSFPs. The E_Port credit configuration is persistent across system reboots and High Availability (HA) failover. Use the portcfgeportcredits --show command to display the configured credits. Use the portBufferShow command to determine current port buffer allocations. 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. The E_Port credits feature does not support ports configured as F_Ports, Mirror Ports, L_Ports, and Trunk Areas. If E_Port credits are configured on ports, moving the ports from one logical switch to another logical switch is not permitted. The Fabric OS port configuration commands are not supported on FCoE ports. The E_Port credits are mutually exclusive with F_Port buffers, longdistance, ISL R_RDY, and Buffer Optimized mode. Operands This command has the following operands: --enable Enables the E_Port credit configuration on a specified port. A port and credits allocation must be specified with this option. --disable Disables the E_Port credit configuration on a specified port. --show Displays the credits configured on a specified port. slot Specifies the slot number on bladed systems, followed by a slash (/).
