'Summary Period' Ethernet Port Statistics

The following statistics are collected for the Ethernet Port object.


Parameter

Type of statistic

Description
Received octets Counter The total number of octets received on the interface, including framing characters (as defined in RFC 2233). This quantity includes errored packets.
Transmitted octets Counter The total number of octets transmitted out of the interface, including framing characters (as defined in RFC 2233). This quantity includes errored packets.
Received utilization Gauge The total number of received octets, divided by the negotiated link speed. Note that the octet count does not include the mandatory Ethernet inter-frame gap, so there may be a minor inaccuracy in this calculation.
Maximum received utilization High Tthe highest percentage utilization for received octets in any 10-second interval during the summary period.
Transmitted utilization Gauge The total number of transmitted octets, divided by the negotiated link speed. Note that the octet count does not include the mandatory Ethernet inter-frame gap, so there may be a minor inaccuracy in this calculation.
Maximum transmitted utilization High Tthe highest percentage utilization for transmitted octets in any 10-second interval during the summary period.
Received unicast packets Counter The total number of unicast packets successfully received on the interface during the summary period. This quantity does not include errored packets.
Transmitted unicast packets Counter The total number of unicast packets sent on the interface during the summary period.
Received multicast packets Counter The total number of multicast packets successfully received on the interface during the summary period. This quantity does not include errored packets.
Transmitted multicast packets Counter The total number of multicast packets sent on the interface during the summary period.
Received broadcast packets Counter The total number of broadcast packets successfully received on the interface during the summary period. This quantity does not include errored packets.
Transmitted broadcast packets Counter The total number of broadcast packets sent on the interface during the summary period.
Alignment errors Counter The number of frames received that were not an integral number of octets in length and did not pass the FCS check (as defined in RFC 2665).
FCS errors Counter The number of frames received that were an integral number of octets in length but did not pass the FCS check (as defined in RFC 2665). This count does not include frames received with frame-too-long or frame-too-short error.
Frame too long errors Counter The number of frames received that exceeded the maximum permitted frame size (as defined in RFC 2665).
Internal MAC receive errors Counter The number of frames that could not be received successfully due to an internal MAC sublayer receive error (as defined in RFC 2665).
Symbol errors Counter The number of symbol errors in received frames (as defined in RFC 2665).
