configured. Statistics types are displayed in the following order by
default:
„
Octets
„

Access — All.
History—Introduced in MSS Version 3.0.
Usage — Each type of statistic is displayed separately. Press the Spacebar
to cycle through the displays for each type.
If you use an option to specify a statistic type, the display begins with that
statistic type. You can use one statistic option with the command.
Use the keys listed in Table 16 to control the monitor display.
For error reporting, the cyclic redundancy check (CRC) errors include
misalignment errors. Jumbo packets with valid CRCs are not counted. A
short packet can be reported as a short packet, a CRC error, or an
overrun. In some circumstances, the transmitted octets counter might
increment a small amount for a port with nothing attached.
