Configuring and Managing the Switch

etherStatsMcastPkts: The number of frames that are detected without errors and are directed to a non-broadcast group address. This doesn’t include frames received with Too Long, Runt, FCS, or Alignment errors.

etherStatsCRCAllignPkts: The number of packets received that had a length (excluding framing bits, but including FCS octets) of between 64 and 1518 octets and had a bad Frame Check Sequence (FCS) with either an FCS error or an Alignment error.

etherStatsUndersizePkts: The number of packets received that were less than 64 octets long (excluding framing bits, but including FCS octets) but were otherwise well-formed.

etherStatsOversizePkts: The number of packets received that were longer than 1518 octets (excluding framing bits, but including FCS octets) but were otherwise well-formed. Might indicate VLAN frames entering the port.

etherStatsRuntPkts: The number of frames detected that are less than the minimum permitted frame size and have a good FCS.

etherStatsJabberPkts: The number of packets received that were longer than 1518 octets (excluding framing bits, but including FCS octets), and had a bad Frame Check Sequence (FCS) with either an FCS error or an Alignment error. The allowed range to detect jabber is between 20 and 150 ms. This is usually caused by a malfunctioning network adapter.

etherStatsCollisions: The number of collisions on this Ethernet segment (port).

etherStatsPkts64Octets: Number of packets 64 octets in length (the minimum size of an Ethernet packet).

etherStatsPkts65to127Octets: Number of packets 65 to 127 octets in length.

etherStatsPkts128to255Octets: Number of packets 128 to 255 octets in length.

etherStatsPkts256to511Octets: Number of packets 256 to 511 octets in length.

etherStatsPkts512to1023Octets: Number of packets 512 to 1023 octets in length.

etherStatsPkts1024to1518Octets: Number of packets 1024 to 1518 octets in length (1518 is the maximum size of an Ethernet packet).
