Monitoring Device Performance 2-11Using the TSX-1620 Hub View
- Out shows the percentage of packets transmitted during the last polling
interval to devices connected to the port. This percentage reflects the
packets transmitted (determined by the change in the port’s MIB-II
ifOutOctets value during the last polling interval, multiplied by 800)
compared to the port’s ifSpeed value.
•Discards shows the percentage of total, inbound, or outbound packets that
were discarded by the port during the last polling interval due to congestion
or filtering.
- Total shows the percentage of packets that were discarded by the port
(determined by adding the port’s MIB-II ifInDiscards and ifOutDiscards)
during the last polling interval due to congestion or filtering. This
percentage reflects the packets discarded compared to the total number of
packets detected at the port:
(ifInDiscards+ifOutDiscards)/(ifInUcastPkts+
ifOutUcastPkts+ifInNUcastPkts+ifOutNUcastPkts).
- In shows the percentage of packets received by the port that were
discarded (determined by the port’s MIB-II ifInDiscards value) during the
last polling interval due to congestion. This percentage reflects the packets
discarded compared to the total number of packets detected at the port:
ifInDiscards/(ifInUcastPkts+ifOutUcastPkts+ifInNUcastPkts+
ifOutNUcastPkts).
- Out shows the percentage of packets filtered (not forwarded) by the port
(determined by the port’s MIB-II ifOutDiscards value) during the last
polling interval. This percentage reflects the packets discarded compared
to the total number of packets detected at the port:
ifOutDiscards/(ifInUcastPkts+ifOutUcastPkts+ifInNUcastPkts+
ifOutNUcastPkts).
•Errors shows the percentage of total, inbound, or outbound packets that were
discarded by the port during the last polling interval due to hardware
reception or transmission errors.
- Total shows the percentage of packets that were discarded by the port
(determined by adding the port’s MIB-II ifInErrors and ifOutErrors
values) during the last polling interval due to hardware reception or
transmission errors. This percentage reflects the packets discarded
compared to the total number of packets detected at the port:
(ifInErrors+ifOutErrors)/
(ifInUcastPkts+ifOutUcastPkts+ifInNUcastPkts+ifOutNUcastPkts).
- In shows the percentage of packets that were discarded by the port
(determined by the port’s MIB-II ifInErrors value) during the last polling
interval due to hardware reception errors. This percentage reflects the
packets discarded compared to the total number of packets detected at the
port: ifInErrors/(ifInUcastPkts+ifOutUcastPkts+ifInNUcastPkts+
ifOutNUcastPkts).
