This feature terminates GRE packets on a TapAgg switch by stripping the GRE header and then letting the decapped packets go through the normal TapAgg path. With this feature, we can use an L3 GRE tunnel to transit tapped traffic to the TapAgg switch over an L3 network. That would widely extend the available use cases for TapAgg.

This article describes the TAP Aggregation 802.1Q (VLAN) tag stripping feature. This feature allows up to two of the outermost incoming 802.1Q tags to be stripped, and can be configured on a traffic steering policy or a tool port.

This article describes the Tap Aggregation MPLS Pop feature. The purpose of this feature is to support tools that do not parse MPLS labels and therefore need the switch to remove (pop) the MPLS header.

This feature provides support for packet counters for Tap Aggregation on default forwarding, traffic steering based on policy map and traffic steering based on traffic policy (Aegis). For brevity, counters for policy-map traffic steering will be referred to as policy-map counters, and counters for traffic-policy traffic steering will be referred to as traffic-policy counters.

As of EOS-4.25.2F some advanced Tap Aggregation features require the hardware forwarding profile to be set. On EOS-4.25.2F these features are MPLS Pop and 802.1br-E/VN Tag Stripping.

Internal recirculation interfaces, IR interfaces, can be used to internally loop-back packets for a second pass through the packet forwarding pipeline. This is particularly useful with Tap Aggregation because some combinations of advanced Tap Aggregation features cannot be simultaneously applied to a packet. Using an IR interface however, a user can apply multiple Tap Aggregation egress editing features, overcoming previous limitations.

In TAP Aggregation mode, when receiving a packet whose Frame Check Sequence (FCS) is corrupted, the default behavior is to replace the bad FCS with the correct value and forward it.

Traffic steering to nexthop groups allows specifying one or more nexthop groups as the destination for a TAP aggregation steering policy. Traffic steering is a TAP aggregation process that uses class maps and policy maps to direct data streams received on TAP ports.
