TapAgg support on MACsec linecards
Introduction Media Access Control Security (MACsec) is an industry standard security technology that provides secure communication for all traffic on Ethernet links. As of EOS 4.20.5F for Arista 7500 lines of switches, users of the tap aggregation features can benefit from using MacSec on tap/tool ports on MacSec capable line cards.
