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.
