EJFAT Status

• Currently using ESnet FPGA f/w build 28 April
  • Specs
  • Jumbo Frames
  • arp, ping, ICMP filtering
  • Port entropy
• Script based LB Control Plane
• EJFAT VLAN Open for Business:
  • Hosts running Ubuntu 20.04
  • 1 Gbs i/f are: ejfat-1, ejfat-2, ejfat-3, ejfat-3, ejfat-5, ejfat-6, ejfat-fs, indra-s2
  • 100 Gbs i/f are: ejfat-1-daq, ejfat-2-daq, ejfat-3-daq, ejfat-3-daq, ejfat-5-daq, ejfat-6-daq, ejfat-fs-daq, indra-s2-daq
