GS716Tv2 and GS724Tv3 Software Administration Manual
Unicast Packets Received The number of subnetwork-unicast packets delivered to a higher-layer
protocol.
Multicast Packets Received The total number of good packets received that were directed to a multicast
address. This number does not include packets directed to the broadcast
address.
Broadcast Packets
Received
The total number of good packets received that were directed to the broadcast
address. This does not include multicast packets.
Total Packets Received with
MAC Errors
The total number of inbound packets that contained errors preventing them
from being deliverable to a higher-layer protocol.
Jabbers Received The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets), and had either a bad Frame
Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad
FCS with a non-integral number of octets (Alignment Error). This definition of
jabber is different than the definition in IEEE-802.3 section 8.2.1.5 (10BASE5)
and section 10.3.1.4 (10BASE2). These documents define jabber as the
condition where any packet exceeds 20 ms. The allowed range to detect
jabber is between 20 ms and 150 ms.
Fragments Received The total number of packets received that were less than 64 octets in length
with ERROR CRC (excluding framing bits but including FCS octets).
Undersize Received The total number of packets received that were less than 64 octets in length
with GOOD CRC (excluding framing bits but including FCS octets).
Alignment Errors The total number of packets received 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 a non-integral number of octets.
Rx FCS Errors The total number of packets received 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
Overruns The total number of frames discarded as 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 which were discarded (i.e., filtered) by the
forwarding process.
Local Traffic Frames The total number of frames dropped in the forwarding process because the
destination address was located off of this port.
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.
Multicast Tree Viable
Discards
The number of frames discarded when a lookup in the multicast tree for a
VLAN occurs while that tree is being modified.
