Tag :: Timestamp

This article describes a feature for Tap Aggregation mode, which supports filtering and forwarding packets with Arista proprietary Tap Aggregation timestamp inserted after MAC address and before VLAN tag and IP header With this feature enabled, timestamped packets can be correctly parsed and be subject to load balancing of port channels and TCAM-based filtering/traffic-steering, the same way as regular packets. When this feature is enabled, regular packets without timestamp are unaffected. This feature may be useful for Arista switches that are expected to receive such timestamped packets so that load balancing, ACL, service policy and traffic policy can be applied to correctly forward and filter such packets.
