# Low Latency Interrupts (LLI)

The LLI feature enables the network device to by-pass the configured interrupt moderation scheme based on the type of data being received. It configures which arriving TCP packets trigger an immediate interrupt, enabling the system to handle the packet more quickly. Reduced data latency enables some applications to gain faster access to network data.

| NOTE: When LLI is enabled, system CPU utilization may increase.

LLI Options:

You may evoke LLI for data packets containing a TCP PSH flag in the header or for specified TCP ports.

Use for packets with TCP PSH flag: | Any incoming packet with the TCP PSH flag will trigger an immediate interrupt. The PSH flag is set by the sending device.
Use for these TCP ports: | Every packet received on the specified ports will trigger an immediate interrupt. Up to 8 ports may be specified.
