7705 SAR Interfaces

Unknown proto
discards
Input/Output
For packet-oriented interfaces, the number of packets received via the
interface that were discarded because of an unknown or unsupported
protocol. For character-oriented or fixed-length interfaces that support
protocol multiplexing, the number of transmission units received via
the interface that were discarded because of an unknown or
unsupported protocol. For any interface that does not support protocol
multiplexing, this counter will always be 0. Unknown proto discards do
not show up in the packet counts.
Port Discard Statistics
Unk L2 Packets
Input/Output
The number of packets discarded due to an unknown L2 ID
CSM Ingress
Queues
Input/Output
The number of incoming control packets discarded
CSM Egress
Queues Output
The number of outgoing control packets discarded
Ethernet-like Medium Statistics
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 that 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
FCS Errors The number of frames received that are an integral number of octets in
length but do not pass the FCS check
SQE Errors The number of times that the SQE TEST ERROR is received
CSE The number of times that the carrier sense condition was lost or never
asserted when attempting to transmit a frame
Too long Frames The number of frames received that exceed the maximum permitted
frame size
Symbol Errors For an interface operating at 100 Mb/s, the number of times there was
an invalid data symbol when a valid carrier was present
Sngl Collisions The number of frames that are involved in a single collision, and are
subsequently transmitted successfully
Mult Collisions The number of frames that are involved in more than one collision and
are subsequently transmitted successfully
