Viewing Device Information 2-13
The Gator Module View
Discarded
Displays the number of packets which were discarded even though they
contained no errors that would prevent transmission. Good packets are typically
discarded to free up buffer space when the network becomes very busy; if this is
occurring routinely, it usually means that network traffic is overwhelming the
device. To solve this problem, you may need to re-configure your bridging
parameters, or perhaps re-configure your network to add additional bridges or
switches.
These statistics are displayed in the pie chart, color-coded magenta.
Error
Displays the number of packets received or transmitted that contained errors.
These statistics are displayed in the pie chart, color-coded red.
Unknown Protocol (Received only)
Displays the number of packets received which were discarded because they were
created under an unknown or unsupported protocol.
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 MRXI will begin to discard packets.
Packets Transmitted (Transmit only)
Displays the number of packets transmitted by this interface.
Making Sense of Detail Statistics
By using a few simple calculations, the I/F Statistics window can give you an idea
of the interface’s activity level and how the interface is performing .
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 Di Transmitted Discards
To calculate the percentage of inbound packets that were discarded:
Received Discards /Packets Received
