MACsec

New

MACsec (Media Access Control Security) is a Layer 2 encryption protocol based on the IEEE 802.1AE standard. It provides hardware-based, low-latency encryption for data in transit over a physical connection. If you enable MACsec when you create a physical port, you can manage MACsec keys on the MACsec tab of the physical port details page.

Failover

New

If multiple VBRs are associated with an ECR, you can enable failover for two or more VBRs. When BFD detects a failure, traffic automatically switches from the failed VBR to a standby VBR within seconds. This ensures service continuity.

Enable fast failover for VBRs on an ECR

ECR flow log

New

ECR now supports flow logs to collect and analyze traffic between VBRs and VPCs, or between VBRs and Transit Router (TR) instances. Use flow logs to monitor traffic patterns and evaluate network throughput and performance.
