Showing Port Statistics
You can display standard statistics on network traffic from the Interfaces
Group MIB, Ethernet-like MIB, and RMOM MIB. These statistics display
errors on the traffic passing through each port. This information can be
used to identify potential problems with the switch (such as a faulty port or
unusually heavy loading). All values displayed have been accumulated since
the last system reboot, and are shown as counts per second. Statistics are
refreshed every 5 seconds.
Note: RMON groups 2, 3 and 9 can only be accessed using SNMP
management software.
Field Attributes
• State – Shows whether or not the port is operational.
• Link – Indicates if the link is Up or Down.
• TxGoodPkt – The total number of packets transmitted out of the
interface, including framing characters.
• TxBadPkt – The number of outbound packets that could not be
transmitted because of errors.
• RxGoodPkt – The total number of packets received on the interface,
including framing characters.
• RxBadPkt – The number of inbound packets that contained errors
preventing them from being delivered to a higher-layer protocol.
• TxAbort – The number of outbound packets which were chosen to be
discarded even though no errors had been detected to prevent their
being transmitted. One possible reason for discarding such a packet
could be to free up buffer space.
• Collision – The best estimate of the total number of collisions on this
Ethernet segment.
• DropPkt – The total number of events in which packets were dropped
due to lack of resources.
