portCfgEport portCfgEport Enables or disables E_Port capability on a port or locks down a port as an E_Port. Synopsis portcfgeport [slot/]port mode portcfgeport -i [index1[-index2] [...] [-f] mode] portcfgeport -slot [slot1[-slot2] [...] portcfgeport -h Description Use this command to enable or disable E_Port capability on a port or to lock down a port as an E_Port. E_Port capability is enabled by default. When an interswitch link (ISL) is connected to a port and the port's E_Port capability is disabled, the ISL is segmented, and all traffic between the switches stops. Fabric management data, such as zoning information, can no longer be exchanged through this port. You can identify a single port to be configured by its port number or by its port index number. Port ranges are supported with index numbers or by specifying a slot or a slot range. Use switchShow for a listing of valid ports, slots, and port index numbers. When used without operands, this command displays all persistently disabled ports on the switch. 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. Changes made by this command are persistent across switch reboots or power cycles. 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. Regardless of how many E_Ports are connected between two switches, the maximum routing paths are limited to 16 E_Ports. The Fabric OS port configuration commands are not supported on FCoE ports. Operands This command has the following operands: slot For bladed systems only, specifies the slot number of the port to be configured, followed by a slash (/). port Specifies the number of the port to be configured, relative to its slot for bladed systems. Use switchShow to display a listing of valid ports. -i index1[-index2] Specifies a range of ports identified by port index numbers. You may specify multiple index ranges separated by a space, for example, -i 33-38 40-60. -f Ignores nonexisting ports. This operand is valid only with the -i option.
