2 portBufferShow NOTES OPERANDS EXAMPLES the return trip of a MARK primitive that is sent and then echoed back to the switch. LD mode supports distances up to 500 km. Distance measurement on a link longer than 500 km might not be accurate. If the connecting port does not support LD mode, is shows "N/A". Remaining Buffers The remaining (unallocated and reserved) buffers in a port group. A hyphen in one of the display fields indicates that no relevant information is available; there may be no connection to a port, or the port is disabled, or the port is not an E_Port. When invoked without operands, this command displays the long distance buffer information for all the port groups of the switch. 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. The following operands are optional: slot For bladed systems only, specifies the slot number of the port group to display, followed by a slash (/). port Specifies the number of a port associated with the port group, relative to its slot for bladed systems. Use switchShow for a list of valid ports.
