2-12 Monitoring Device Performance

- Out shows the percentage of packets that were discarded by the port

(determined by the port’s MIB-II ifOutErrors value) during the last

polling interval due to hardware transmission errors. This percentage

reﬂects the packets discarded compared to the total number of packets

detected at the port:

ifOutErrors/(ifInUcastPkts+ifOutUcastPkts+ifInNUcastPkts+

ifOutNUcastPkts).

•Non-Unicast (Nucast) shows the percentage of packets transmitted or

received by the port during the last polling interval that were multicast

packets.

- Total shows the percentage of packets transmitted or received by the port

during the last polling interval that were multicast packets. This

percentage reﬂects the multicast packets detected (determined by adding

the port’s MIB-II ifInNUcastPkts and ifOutNUcastPkts values) compared

to the total number of packets detected at the port: (ifInNUcastPkts+

ifOutNUcastPkts)/(ifInUcastPkts+ifOutUcastPkts+ifInNUcastPkts+

ifOutNUcastPkts).

- In shows the percentage of packets received by the port during the last

polling interval that were multicast packets. This percentage reﬂects the

multicast packets detected (determined by the port’s MIB-II

ifInNUcastPkts value) compared to the total number of packets detected

at the port:

ifInNUcastPkts/(ifInUcastPkts+ifOutUcastPkts+ifInNUcastPkts+

ifOutNUcastPkts).

- Out shows the percentage of packets transmitted by the port during the

last polling interval that were multicast packets. This percentage reﬂects

the multicast packets detected (determined by the port’s MIB-II

ifOutNUcastPkts value) compared to the total number of packets

detected at the port:

ifOutNUcastPkts/(ifInUcastPkts+ifOutUcastPkts+ifInNUcastPkts

+ifOutNUcastPkts).

Port Color Codes for the Interface Application Display

For each port display form, the color-coding of each interface reﬂects a

combination of MIB-II interface operational status (ifOperStatus), administrative

status (ifAdminStatus), and the interface’s physical link status (if it applies).

Green On — The interface’s operational status is returned as “UP” —

and it has been administratively enabled; if the interface

supports link state, a physical link has been detected at the port.

NOTE

For the statistical port display form options listed above, three dashes (---) will display for

all inactive ports; any active (green) port will display a numeric value, even if it’s 0 (zero).
