6.1 Receive & Transmit
Good Octets: An octet is a sequence of eight bits. Since a byte is not
eight bits in all computer systems, octet provides an
unambiguous term.
Total good packets: Total number of packets without errors received. For the
transmit direction this is expressed as total packets sent,
since only good packets are sent.
Unicast: Total number of unicast packets. Unicast packets are
packets addressed to a single host on a LAN.
Broadcasts: Total number of broadcast packets. Broadcast packets are
packets addressed to all hosts on a LAN.
Multicasts: Total number of multicast packets. Multicast packets are
packets addressed to a subset of hosts on a LAN.
Pauses: Pause frames are sent if flow control is enabled and a port
needs to temporarily stop the flow of incoming packets.
Undersized: Number of packets received that are smaller then 64 bytes.
Fragments: Number of partial packets received.
Oversized: Number of packets received that exceed 1518 bytes (or
1522 bytes with an 802.1q VLAN tag). These errors are
caused either by damaged packets or by user network
equipment being configured to transmit jumbo frames.
Jabber errors: Packets received after a pause frame has been sent to the
remote end. It is likely that flow control is disabled at the
remote end and enabled at local end of the connection; this
problem is most easily solved by setting both ends of the
link to either have flow control enabled or disabled.
PHY errors: Receive errors on the physical interface.
