Napatech Link-Capture™ Software offers two different port configurations, 4×10G and 1×40G, for Intel® PAC A10 GX.
AFU image files
The firmware part of Napatech Link-Capture™ Software is packaged as FPGA image files. FPGA image files for Intel® PAC A10 GX are known as AFU (Accelerator Functional Unit) image files. AFU image files can be dynamically loaded to Intel® PAC A10 GX acceleration cards.
|Port configuration||AFU filename|
AFU image files are also known as Green BitStream files and commonly use .gbs as the filename extension. AFU image files for use with Napatech Link-Capture™ Software are encrypted and use .egbs as the filename extension.
During initialization, ntservice reads /opt/napatech3/config/afu.ini and /opt/napatech3/config/ntlicense.key and loads the specified encrypted AFU image files. Your license key is valid for both types of port configuration. See Installing the License Key for Napatech Link-Capture™ Software for information about how to order and install a license key file.
Selecting 4×10G or 1×40G
- Backup any previous version of the /opt/napatech3/config/afu.ini
The installation will overwrite any previous versions.
- Run the /opt/napatech3/bin/nt_afu_ini_setup.sh configuration
script to select an AFU image file for each installed Intel® PAC A10 GX:
- If /opt/napatech3/config/afu.ini already exists, it is displayed.
Type Y to confirm
OK: 1x40G image found /opt/napatech3/images/INTEL-A10-1x40/200-7001-12-03-00-180817-1210.egbs >> Configure AFU images for PCI device found in PCI-slot 0000:04:00.0 - ([Y]es/[N]o) ?
- If /opt/napatech3/config/afu.ini does not exist, or if you
confirm reconfiguration, the script displays bus IDs for the installed Intel® PAC A10 GX SmartNICs and file
names for available AFU image files.For each Intel® PAC A10 GX, choose whether to select another AFU image file and which one:
>> Configure AFU images for PCI device found in PCI-slot 0000:04:00.0 - ([Y]es/[N]o) ? >> select 4x10G (press 1) or 1x40G (press 2)Here is a sample of the commands and output:
