Line Swap Fast Recovery
Using Line-Swap-Fast-Recovery
The Line-Swap Fast Recovery function, which is enabled by default, allows the NPort S8000 to return to normal
operation extremely quickly after devices are unplugged and then re-plugged into different ports. The recovery
time is on the order of a few milliseconds (compare this with standard commercial switches for which the
recovery time could be on the order of several minutes). To disable the Line-Swap Fast Recovery function, or
to re-enable the function after it has already been disabled, access either the Console utility’s Line-Swap
recovery page, or the Web Browser interface’s Line-Swap fast recovery page, as the following figure
shows:

Ethernet Traffic Prioritization
Using Traffic Prioritization
The NPort S8000’s traffic prioritization capability provides Quality of Service (QoS) to your network by making
data delivery more reliable. You can prioritize traffic on your network to ensure that high priority data is
transmitted with minimum delay. Traffic can be controlled by a set of rules to obtain the required Quality of
Service for your network. The rules define different types of traffic and specify how each type should be treated
as it passes through the switch. The NPort S8000 can inspect both IEEE 802.1p/1Q layer 2 CoS tags, and even
layer 3 TOS information to provide consistent classification of the entire network. The NPort S8000’s QoS
capability improves the performance and determinism of industrial networks for mission critical applications.
