Port Statistics
The Switch 9100 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 two seconds. Values are displayed to nine digits of
accuracy.
To view port statistics, use the following command:
show ports <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)
■
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.
