Viewing Port Statistics

ExtremeXOS software provides a facility for viewing port statistical information. The summary information lists values for the current counter for each port in the system. The switch automatically refreshes the display (this is the default behavior).

You can also display a snapshot of the real-time port statistics at the time you issue the command and view the output in a page-by-page mode. This setting is not saved; therefore, you must specify the no-refresh parameter each time you want a snapshot of the port statistics.

Values are displayed to nine digits of accuracy.

View port statistics with the following command:
show ports {port_list | stack-ports stacking-port-list} statistics {no-refresh}
The switch collects the following port statistical information:
- Link State—The current state of the link. Options are:
  - Active (A)—The link is present at this port.
  - Ready (R)—The port is ready to accept a link.
  - Loopback (L)—The port is configured for WANPHY loopback.
- Transmitted Packet Count (TX Pkt Count)—The number of packets that have been successfully transmitted by the port.
- Transmitted Byte Count (TX Byte Count)—The total number of data bytes successfully transmitted by the port.
- Received Packet Count (RX Pkt Count)—The total number of good packets that have been received by the port.
- Received Byte Count (RX Byte Count)—The total number of bytes that were received by the port, including bad or lost frames. This number includes bytes contained in the Frame Check Sequence (FCS), but excludes bytes in the preamble.
- Received Broadcast (RX Bcast)—The total number of frames received by the port that are addressed to a broadcast address.
- Received Multicast (RX Mcast)—The total number of frames received by the port that are addressed to a multicast address.
