Monitoring Device Performance

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+

).

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

 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+

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.
