Statistics
4-8 IF Statistics
The lower portion of the window provides the following transmit and receive
statistics; note that the Þrst four statistics are also graphically displayed in the pie
charts.
Unicast
Displays the number of packets transmitted to or received from this interface that
had a single, unique destination address. These statistics are displayed in the pie
chart, color-coded green.
Non-Unicast
Displays the number of packets transmitted to or received from this interface that
had a destination address that is recognized by more than one device on the
network segment. The non-unicast Þeld includes a count of broadcast packets Ñ
those that are recognized by all devices on a segment. These statistics are
displayed in the pie chart, color-coded dark blue.
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 trafÞc is overwhelming the
device. To solve this problem, you may need to re-conÞgure your bridging
parameters, or perhaps re-conÞgure your network to add additional bridges.
Consult the Cabletron Systems Network Troubleshooting Guide for more
information.
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 trafÞc
level on the target network, determine how large the output packet queue can
grow before the SmartSwitch 2000 will begin to discard packets.
Packets Transmitted
(Transmit only)
Displays the number of packets transmitted by this interface.
