The 9A128-01 Module View
2-18 Viewing Module Information
Three informational fields appear in the upper portion of the window:
Description
Displays the interface description for the currently selected port: Ctron SMB 1,
Ctron SMB 10, FDDI, or ATM.
Address
Displays the MAC (physical) address of the selected port.
Type
Displays the interface type of the selected port: sdlc (for SMB 1), ethernet-csmacd
(for SMB 2), fddi, or atm.
The lower portion of the window provides the following transmit and receive
statistics; note that the first 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 field includes a count of broadcast packets —
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 traffic is overwhelming the
device. To solve this problem, you may need to re-configure your bridging
parameters, or perhaps re-configure you network to add additional bridges or
switches. 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.
