Hierarchy Level


Enables the low-latency mode on the selected NP-IOC. Low-latency is not enabled by default. The low latency allows you to configure the mode of the network processor’s traffic manager (TM) on the egress path. If low latency is enabled, the network processor is initialized without the traffic manager, thus reducing the overall latency in the Express Path (formerly known as services offloading).


Because all SRX Series CoS functions are supported by the traffic manager, CoS functions are not supported when low latency is enabled.
