Port Statistics
The switch software provides a facility for viewing port statistic
information. The summary information lists values for the current
counter against each port on each operational module in the system,
and it is refreshed approximately every 2 seconds. Values are
displayed to nine digits of accuracy.
To view port statistics:
Use the following command:
show ports
The following port statistic information is collected by the switch:
❑ Link Status — The current status of the link. Options are
— Ready (the port is ready to accept a link)
— Active (the link is present at this port)
❑ Transmit Packet Count (Tx Pkt Count) — The number of
packets that have been successfully transmitted by the port.
❑ Transmit Byte Count (Tx Byte Count) — The total number of
data bytes successfully transmitted by the port.
❑ Total Collisions — The total number of collisions seen by the
port, regardless of whether a device connected to the port
participated in any of the collisions.
❑ 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.
❑ Receive Broadcast (RX Bcast) — The total number of frames
received by the port that are addressed to a broadcast
address.
❑ Receive Multicast (RX Mcast) — The total number of frames
received by the port that are addressed to a multicast address.
