Packets
Transmitted
Octets
•
Total Bytes
- The total number of octets of data (including those in bad packets) received on the
network (excluding framing bits but including FCS octets). This object can be used as a reasonable
estimate of Ethernet utilization. If greater precision is desired, the etherStatsPkts and
etherStatsOctets objects should be sampled before and after a common interval. -----
•
Packets Transmitted 64 Octets
- The total number of packets (including bad packets) received
that were 64 octets in length (excluding framing bits but including FCS octets).
•
Packets Transmitted 65-127 Octets
- The total number of packets (including bad packets)
received that were between 65 and 127 octets in length inclusive (excluding framing bits but
including FCS octets).
•
Packets Transmitted 128-255 Octets
- The total number of packets (including bad packets)
received that were between 128 and 255 octets in length inclusive (excluding framing bits but
including FCS octets).
•
Packets Transmitted 256-511 Octets
- The total number of packets (including bad packets)
received that were between 256 and 511 octets in length inclusive (excluding framing bits but
including FCS octets).
•
Packets Transmitted 512-1023 Octets
- The total number of packets (including bad packets)
received that were between 512 and 1023 octets in length inclusive (excluding framing bits but
including FCS octets).
•
Packets Transmitted 1024-1518 Octets
- The total number of packets (including bad packets)
received that were between 1024 and 1518 octets in length inclusive (excluding framing bits but
including FCS octets).
•
Max Frame Size
- The maximum size of the Info (non-MAC) field that this port will receive or
transmit.
Packets
Transmitted
Successfully
•
Total
- The number of frames that have been transmitted by this port to its segment.
•
Unicast Packets Transmitted
- The total number of packets that higher-level protocols requested
be transmitted to a subnetwork-unicast address, including those that were discarded or not sent.
•
Multicast Packets Transmitted
- The total number of packets that higher-level protocols requested
be transmitted to a Multicast address, including those that were discarded or not sent.
•
Broadcast Packets Transmitted
- The total number of packets that higher-level protocols
requested be transmitted to the Broadcast address, including those that were discarded or not sent.
Transmit Errors
•
Total Errors
- The sum of Single, Multiple, and Excessive Collisions.
•
Tx FCS Errors
- The total number of packets transmitted that had a length (excluding framing bits,
but including FCS octets) of between 64 and 1518 octets, inclusive, but had a bad Frame Check
Sequence (FCS) with an integral number of octets.
•
Oversized
- The total number of frames that exceeded the max permitted frame size. This counter
has a max increment rate of 815 counts per sec. at 10 Mb/s.
•
Underrun Errors
- The total number of frames discarded because the transmit FIFO buffer became
empty during frame transmission.
Transmit Discards
•
Total Discards
- The sum of single collision frames discarded, multiple collision frames discarded,
and excessive frames discarded.
•
Single Collision Frames
- A count of the number of successfully transmitted frames on a particular
interface for which transmission is inhibited by exactly one collision.
•
Multiple Collision Frames
- A count of the number of successfully transmitted frames on a
particular interface for which transmission is inhibited by more than one collision.
•
Excessive Collisions
- A count of frames for which transmission on a particular interface fails due
to excessive collisions.
•
Port Membership Discards
- The number of frames discarded on egress for this port due to egress
filtering being enabled.
