SFTOS Command Reference for the S2410, Version 2.4.1.0 71
Packets Received 1519-1522 Octets The total number of packets (including bad packets) received
that were between 1519 and 1522 octets in length inclusive
(excluding framing bits but including FCS octets).
Packets Received > 1522 Octets The total number of packets received that were longer than
1522 octets (excluding framing bits, but including FCS octets)
and were otherwise well formed.
Packets Received Successfully
Total The total number of packets received that were without errors
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. Note that 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. Note that this does not include
multicast packets.
Packets Received with MAC Errors
Total 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). Note that 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/Undersize Received The total number of packets received that were less than 64
octets in length (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
Received Packets not forwarded
Total A count of valid frames received which were discarded (i.e.
filtered) by the forwarding process
