Rx FCS Errors The total number of packets received with 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
Overruns The total number of frames discarded because this port was overloaded with
incoming packets, and could not keep up with the inflow.
Total Received Packets Not
Forwarded
A count of valid frames received that were discarded (that is, filtered) by the
forwarding process.
802.3x Pause Frames
Received
A count of MAC control frames received on this interface with an opcode
indicating the PAUSE operation. This counter does not increment when the
interface is operating in half-duplex mode.
Unacceptable Frame Type The number of frames discarded from this port due to being an
unacceptable frame type.
Total Packets Transmitted
(Octets)
The total number of octets of data (including those in bad packets)
transmitted 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
must 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).
Packets Transmitted > 1518
Octets
The total number of packets transmitted that were longer than 1518 octets
(excluding framing bits, but including FCS octets) and were otherwise well
formed. This counter has a max increment rate of 815 counts per sec at 10
Mb/s.
Maximum Frame Size The maximum Ethernet frame size the interface supports or is configured to
use, including Ethernet header, CRC, and payload. (1518 to 9216). The
default maximum frame size is 1518.
