port has been lost. If the failure occurs on the fiber optic cabling, the line
card drops the link to the twisted pair port.
Some devices can be configured to take a specific action in the event of
the loss of connection on a port, to seek a redundant path to a
disconnected end node, or to send out a trap to a network management
station, and so alert the network administrator of the problem.
Smart
MissingLink
The Smart MissingLink feature performs exactly the same function as
MissingLink™ with one additional feature. When a link is lost on a port, the
LK LED of the port that still has a valid connection to its end node starts to
blink. This allows you to quickly determine which port still has a valid
connection (LK LED blinking) and which port has lost its connection (LK
LED is off).
For example, if the network twisted pair cable to the 10/100Base-TX port
on the media converter fails, the LK LED on the 100Base-FX fiber optic
port blinks, indicating a failed connection on the twisted pair port. If the
failure starts with the fiber optic cabling, the LK LED on the twisted pair
port blinks.
This allows you to quickly see which port has failed and troubleshoot your
network accordingly.
OAM
The Operation, Administration and Maintenance (OAM) is a group of
functions that provides tools and utilities used to manage a network. The
OAM feature is 802.3ah-compliant and is used to provide network
indication, system configuration, performance monitoring, security
management, diagnostic functions and configuration. OAM is described in
detail in the AT-S70 Management Software User’s Guide.
