Rx Dropped Identifies the number of superpackets that were
received out of sequence during the given hour.
This can result from one or more superpacket's being
lost or delivered out of order and, thus, discarded.
%Error Identifies the packet error percentage that was
received during the given hour.
Remote Gateway 9100 Series begins calculating this
statistic by adding the number out-of-sequence packets
(Rx Dropped) to the number of overruns. After
multiplying this sum by 100, Remote Gateway 9100
Series then divides the product by the number of
received decoder packets (Rx Voice Samples) to
produce the error percentage.
This is an imprecise measurement due to the fact that
multiple packet losses or overruns can be counted as a
single error.
EthTx Mcast Identifies the number of multicast packets transmitted
during the given hour.
Multicast packets are packets intended for multiple
Ethernet addresses.
EthTX Ucast Identifies the number of unicast packets transmitted
during the given hour.
Unicast packets are packets intended for a specific
Ethernet address. Voice packets are always transmitted
as unicast packets.
EthTx Disc Identifies the number of packets discarded on the
transmit side due to lack of resources, such as memory
buffers, during the given hour.
This can be an indirect result of excessive collisions in
the transmit queue.
