Port Assignment
If you choose Port Assignment, each port’s status box will display a letter which
designates its current repeater channel assignment (A-H).
Errors or Frame Size
If you choose the Errors or Frame Size modes, additional menus offer the
following options for each mode:
Errors Total Errors, Collisions, Alignment, CRC, Runts, Giants,
or OOW Collisions
Frame Size Runts, 64-127, 128-255, 256-511, 512-1023, 1024-1518, or
Giants
The port status boxes will display the percentage for each active port that
represents what portion of that port’s total traffic is of the specific type (Errors or
Frame Sizes) that you selected.
Select one of the Errors options to see what percentage of the total packets
received by each active port during the last polling interval was of the error type
you selected. This percentage reflects the number of errors generated by devices
connected to that port in relation to the total number of packets processed by the
port (errors ÷ [errors + packets]).
Choose the Frame Size option to check on the sizes, in bytes, of frames passing
through your ports. The percentages are calculated just like the Errors selection
described above: the number given represents the number of packets of the
selected size generated by devices connected to that port in relation to the total
number of packets processed. Remember, these percentages are calculated based
on the numbers of packets processed during one polling cycle.
NOTE
Because BNC thin coax and AUI ports do not support the link feature, the displayed
Admin/Link, Admin, and Link status conditions will not always follow the pattern
described above:
Under Admin/Link status mode, BNC ports will display as ON if there is a valid
connection and the port has been enabled; OFF if the port has been disabled; and SEG if
the port has experienced 33 consecutive collisions or if there is no cable attached. A n AUI
port will display as ON if the port has been enabled (regardless of whether or not there is a
valid connection), OFF if the port has been disabled, and SEG if the port has detected 33
consecutive collisions. Note that the Admin/Link status displays for BNC and AUI ports
can be misleading in terms of troubleshooting; be sure to keep in mind that a BNC port
displaying as segmented may only have had its cable disconne cted, and an AUI port that
appears to be on and linked may not have any cable attached.
Under Admin status mode, AUI and BNC ports will display as ON if the port has been
enabled, and OFF if it has been disabled; as with other port types, these ON and OFF
conditions indicate nothing about link status.
Under Link status mode, AUI and BNC port display boxes will display N/A, indicating
that NetSight Element Manager is unable to determine their link status.
