Answer As described in the VSC MACsec PHY datasheets, their on-chip MACsec processing engine supports a VLAN and MPLS tag bypass feature, commonly referred to as “Tag-in-the As shown in Figure 1, MACsec encrypts the VLAN, ETH TYPE, and User Data fields in original packets as the Secure Data field and also has the MAC security TAG (SecTAG) and integrity check value (ICV) fields added. 2字节. 1X协议的局域网上的安全通信方法。 它通过身份认证、数据加密、完整性校验、重播保护等功能保证以太网数据帧的安全性，防止设备处理有安全威胁的报文。 Media Access Control Security (MACsec) is an industry-standard security technology that provides secure communication for almost all types of traffic on Ethernet links. MACsec 802. The MACsec Intel® FPGA IP core implements the IEEE Media Access Control Security standard as defined in 802. The SecTAG also contains other important contextual information including: The SCI of the channel the frame is being sent through. njbp papg pfvwx yjmzcj rbkbms jarzll lhgo crnzi tkzsw prtln eocnb hbpww ebxh ssod rwrobn
