ORT
The BlackDiamond 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 port <slot:portlist> stats
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.
— Chassis — The link is connected to a Summit Virtual Chassis.
• 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.
