Port Commands
monitor port counters (continued)
Defaults: All types of statistics are displayed for all ports. MSS refreshes the statistics every
5 seconds. This interval cannot be configured. Statistics types are displayed in the
following order by default:
• Octets
• Packets
• Receive errors
• Transmit errors
• Collisions
• Receive Ethernet statistics
• Transmit Ethernet statistics
Access: All
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 the table below to
control the monitor display.
Key Effect on Monitor Display
Spacebar Advances to the next statistic type.
Esc Exits the monitor. MSS stops displaying the statistics
and displays a new command prompt.
c Clears the statistics counters for the currently
displayed statistics type. The counters begin
incrementing again.
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.
Examples: The following command starts the port statistics monitor beginning with octet
statistics (the default):
DWS-1008# monitor port counters
As soon as you press Enter, MSS clears the window and displays statistics at the top of the
window.
