2 portCfgSpeed portCfgSpeed Configures the speed for a port or a range of ports. SYNOPSIS portcfgspeed [slot/]port speed portcfgspeed -i [index1[-index2] [-f] speed] portcfgspeed -x [hex1[-hex2] [...]] portcfgspeed -slot [slot1[-slot2] [...] speed portcfgspeed -h DESCRIPTION NOTES OPERANDS Use this command to set the speed on a specified port or port range. This command disables and then re-enables the ports, and the ports come online with the new speed setting. The configuration is saved in nonvolatile memory and is persistent across switch reboots or power cycles. Use the portShow command to display supported port speed levels. Use the portCfgShow command to display configured speed settings. On Condor 3-based plat forms ,the portCfgSpeed command checks if the requested speed is allowed, based on the combination configured for the octet that contains the port. If the speed is not supported by the current octet speed combination, this command exits with a warning message that displays the combination compatible with desired speed . Use the portCfgOctetSpeedCombo command to the set the suggested combination before re-executing the portCfgSpeed command. You can identify a single port to be configured by its port number or by its port index number in decimal or hexadecimal format. Port ranges are supported with port numbers, index numbers(decimal or hexadecimal) or by specifying a slot or a slot range. Use switchShow for a listing of valid ports, slots, and port index numbers. Specifying multiple ports with the index (-i) or slot (-s) option is supported only if PortSwap is disabled. They are not supported on GbE ports and configured F_Port trunks. Use the -i option without a port index argument to display the portSwap status, or alternately use portSwapShow. This configuration cannot be set on VE/VEX_Ports. For a virtual FC port, the speed is always 10 GbE and port speed autonegotiation is not possible. Speed configuration is not applicable to FCoE 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. This command has the following operands: slot For bladed systems only, specifies the slot number of the ports to be configured, followed by a slash (/). port Configures a single port identified by the port number relative to the slot on bladed systems. -i index1[-index2] Configures a port or a range of ports identified by port index numbers. Multiple port ranges are not supported with this command. -f Ignores nonexisting ports. This operand is valid only with the -i option. 718 Fabric OS Command Reference 53-1002746-01
