Total Errors - the sum of Single, Multiple, and Excessive Collisions.
FCS Errors - the total number of packets transmitted 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
Oversized - the total number of frames that exceeded the max permitted frame
size. This counter has a max increment rate of 815 counts per sec. at 10 Mb/s.
Underrun Errors - the total number of frames discarded because the transmit
FIFO buffer became empty during frame transmission.
Transmit Discards
Total Discards - the sum of single collision frames discarded, multiple collision
frames discarded, and excessive frames discarded.
Single Collision Frames - a count of the number of successfully transmitted
frames on a particular interface for which transmission is inhibited by exactly
one collision.
Multiple Collision Frames - a count of the number of successfully transmitted
frames on a particular interface for which transmission is inhibited by more than
one collision.
Excessive Collisions - a count of frames for which transmission on a particular
interface fails due to excessive collisions.
Port Membership - the number of frames discarded on egress for this port due
to egress filtering being enabled.
VLAN Viable Discards - the number of frames discarded on this port when a
lookup on a particular VLAN occurs while that entry in the VLAN table is being
modified, or if the VLAN has not been configured.
Protocol Statistics
BPDU's received - the count of BPDU's (Bridge Protocol Data Units) received
in the spanning tree layer.
BPDU's Transmitted - the count of BPDU's (Bridge Protocol Data Units)
transmitted from the spanning tree layer.
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.
GVRP PDU's Received - the count of GVRP PDU's received in the GARP
layer.
GVRP PDU's Transmitted - the count of GVRP PDU's transmitted from the
GARP layer.
GVRP Failed Registrations - the number of times attempted GVRP
registrations could not be completed.
GMRP PDU's received - the count of GMRP PDU's received in the GARP
layer.
GMRP PDU's Transmitted - the count of GMRP PDU's transmitted from the
GARP layer.
GMRP Failed Registrations - the number of times attempted GMRP
registrations could not be completed.
