WebPAUSE frames, or Xoff frames, appear in the output of the ifstat -a -v command. In 10Gbps, the ifstat –a command might list 'PAUSE' frames; in 1Gbps, it will typically be listed as Xoff and Xon. A PAUSE frame includes the period of pause time being requested, in the form of a two byte unsigned integer (0 through 65535) known as a 'quanta'.

WebFrom Wikipedia, the free encyclopedia. A cyclic redundancy check ( CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents.
