3.1. MACsec Intel FPGA IP Parameter Settings
|Snapshot Enable for Statistics Counters.
Controlled ports for encryption and decryption lanes.
|Uncontrolled Port Enable
|Indicates whether the uncontrolled ports for both transmit and receive lanes are enabled to receive user traffic. When disabled, the uncontrolled ports are hidden from the user.
|Number of TX+RX Ports
|The number of Controlled Ports supported in MACsec for all ports and streams. In ENCRYPT_DECRYPT mode, the number of TX ports always equals the number of RX ports.
|Interface Property Tab
|Port VLAN Clear
|Defines whether VLLAN Clear is supported for Port X.
|User Data Width
|Width of data bus inside the MACsec IP's Port MUX & DEMUX blocks. This indicates the width of data after being muxed which is coming into the MACsec IP and the width of data before demuxing and being sent out of the MACsec IP. Supported values are 256 and 512.
|Indicates there is user metadata which is tagged along with incoming/outgoing packets into the MACsec IP. Required to support PTP use case.
|Selects the port for which parameters are to be configured.
|Port Data Width
|Width of the AXI-ST data ports at the edge of the MACsec IP as presented to the MUX and DEMUX blocks. This indicates the width of AXI-ST data ports before being muxed which is coming into the MACsec IP and the width of data after demuxing and being sent out of the MACsec IP. Supported values are 64, 128, 256, and 512.
|Arbiter Ready Latency
|Mux/Demux per-port ready latency on the AXI-ST ports at the edge of the MACsec IP. Defines the association between assertion of the READY signal and the corresponding VALID on the Port Mux/Demux and MACsec SIP interface.
|802_1AE-2018 Options Tab
|Strict, Check, Disable, Null
|Indicates the transmitted/received frames check level.
|Frames Protection Enable
|Enables Anti-Replay Protection check on packets which go through the RX path.
|Indicates whether the 64b Extended Packet Number is supported.
|Example Designs Tab
|Example Design Files
|Selects the supported example design to be generated.
The example design generates with only the Example Design Options specified in the drop-down menu. No other IP parameters that you specify applies to the example design generation.
|Required to be checked to generate an example design. When checked, you acknowledge that the example design generates with ONLY the Example Design options specified in the drop-down menu, and that no other IP parameters which you specify apply to the generated Example Design.
|Generated HDL Format
|General file format
|HDL format of generated files.
