HP Moonshot Switch Module CLI Command Reference
• Packets RX and TX 512–1023 Octets - The total number of packets (including bad
packets) received and transmitted that were between 512 and 1023 octets in length
inclusive (excluding framing bits but including FCS octets).
• Packets RX and TX 1024–1518 Octets - The total number of packets (including bad
packets) received and transmitted that were between 1024 and 1518 octets in length
inclusive (excluding framing bits but including FCS octets).
• Packets RX and TX 1519–2047 Octets - The total number of packets received and
transmitted that were between 1519 and 2047 octets in length inclusive (excluding
framing bits, but including FCS octets) and were otherwise well formed.
• Packets RX and TX 2048–4095 Octets - The total number of packets received that were
between 2048 and 4095 octets in length inclusive (excluding framing bits, but including
FCS octets) and were otherwise well formed.
• Packets RX and TX 4096–9216 Octets - The total number of packets received that were
between 4096 and 9216 octets in length inclusive (excluding framing bits, but including
FCS octets) and were otherwise well formed.
Packets Received
Successfully
• Total Packets Received Without Error - 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.
Receive Packets
Discarded
The number of inbound packets which were chosen to be discarded even though no errors
had been detected to prevent their being deliverable to a higher-layer protocol. One
possible reason for discarding such a packet could be to free up buffer space.
Packets Received
with MAC Errors
• 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). 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.
• 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.
