The Device View
If you have selected the Link status mode, a port is considered:
•LNK (Linked) when a valid link has been established between the port and the device at the other end of the segment.
•NLK (Not Linked) when the port is on, but there is no physical link to the port or the device at the other end of the port’s segment is down.
•N/A (not available) when NetSight Element Manager cannot determine the link status for the port.
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. An 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 disconnected, 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.
