TATISTICS

The Summit provides a facility for viewing port statistic information. The summary
information lists values for the current counter against every port on the Switch, and it
is refreshed approximately every two seconds. Values are displayed to nine digits of
accuracy.

To view port statistics, enter

show port <portlist> stats

The following port statistic information is collected by the Switch:

¥ Link Status Ñ

The current status of the link. Options are

Ñ

Ready Ñ The port is ready to accept a link.

Ñ

Active Ñ The link is present at this port.

¥ Transmit Packet Count (Tx Pkt Count) Ñ

The number of packets that have been

successfully transmitted by the port.

¥ Transmit Byte Count (Tx Byte Count) Ñ

The total number of data bytes

successfully transmitted by the port.

¥ Total Collisions Ñ

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) Ñ

The total number of good packets that

have been received by the port.

¥ Received Byte Count (RX Byte Count) Ñ

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)

Ñ The total number of frames received by the port

that are addressed to a broadcast address.

¥ Receive Multicast (RX Mcast)

Ñ The total number of frames received by the port

that are addressed to a multicast address.
