Interface Statistics 3-9
Statistics
Packets Received (Received only)
Displays the number of packets received by the selected interface.
Transmit Queue Size (Transmit only)
Displays the number of packets currently queued for transmission from this
interface. The amount of device memory devoted to buffer space, and the traffic
level on the target network, determine how large the output packet queue can
grow before the MultiSwitch 700 module will begin to discard packets.
Packets Transmitted (Transmit only)
Displays the number of packets transmitted by this interface.
Making Sense of Interface Statistics
The statistics available in this window can give you an idea of how an interface is
performing; by using the statistics in a few simple calculations, it’s also possible to
get a sense of an interface’s activity level:
To calculate the percentage of input errors:
Received Errors /Packets Received
To calculate the percentage of output errors:
Transmitted Errors /Packets Transmitted
To calculate the total number of inbound and outbound discards:
Received Discards + Transmitted Discards
To calculate the percentage of inbound packets that were discarded:
Received Discards /Packets Received
To calculate the percentage of outbound packets that were discarded:
Transmit Discards /Packets Transmitted
