TS
The Ethernet Stats web page reports TCP throughput and error information for the
Ethernet
connection of the subscriber module. The following definitions are
available:
inoctets count:
displays the total number of octets received on the interface, including
framing
characters.
inucastpkts count:
displays the total number of subnetwork-unicast packets delivered to a
higher
layer
protocol
innucastpkts count:
displays the total number of non-unicast (i.e. subnetwork-broadcast
or
subnetwork-multicast) packets delivered to a higher layer
protocol.
indiscards count:
displays the total number of inbound packets which were chosen to
be
discarded even though no errors had been detected to prevent their be deliverable to higher
layer
protocol. One possible reason to discard could be to free up buffer
space.
inerrors count:
displays the total number of inbound packets that contained errors
preventing
them from being delivered to a higher layer
protocol.
inunknownprotos count:
displays the total number of packets received via the interface
which
were discards because of an unknown or unsupported
protocol.
outoctets count:
displays the total number of octets transmitted out of the interface,
including
framing
characters.
outucastpkts count:
displays the total number of packets that higher-level protocols requested
be
transmitted to a subnetwork-unicast address, including those that were discarded or not
sent.
outnucastpkts count:
displays the total number of packets that higher-level protocols
requested
be transmitted to a non-unicast (i.e. subnetwork-broadcast or subnetwork-multicast)
address,
including those that were discarded or not
sent.
outdiscards count:
displays the total number of outbound packets which were chosen to
be
discarded even though no errors had been detected to prevent their being transmitted.
One
possible reason for discarding such a packet could be to free up buffer
space.
outerrrors count:
displays the total number of outbound packets that could not be
transmitted
because of
errors.
RxBabErr:
displays the total number of receiver babble
errors
EthBusErr:
displays the total number of Ethernet bus errors on the Ethernet
controller.
CRCError:
displays the total number of CRC errors on the Ethernet
controller.
RxOverrun:
displays the total number of receiver-overrun errors on the Ethernet
controller.
Late
Collision:
displays the total number of late collisions on the Ethernet controller. A
normal
collision occurs during the first 512 bits of the frame transmission. If a collision occurs after the
512
