This article describes a feature for Tap Aggregation mode, which strips IEEE 802.1BR E-Tag and Cisco VN-Tag headers from all tagged packets received on tap interface before delivering them out of tool interfaces.

This feature enables Tap Aggregation generic header removal on a tap port. We support the removal of a number of bytes immediately following the ethernet header, including the VLAN tags. The number of bytes to be removed must be an even number less than or equal to 62. The original ethernet header will be removed by default but there is an option in the CLI command to preserve it.

This feature terminates GRE packets on a TapAgg switch by stripping the GRE header and then letting the decapped

This feature extends the capabilities of Tap Aggregation traffic steering to allow for using traffic policies.

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 MAC Address Replacement feature. This feature provides the ability to configure user-specific values to replace the destination and source MAC addresses of packets forwarded by Tap Aggregation.

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.

Timestamping is an important tool for network engineering and performance analysis. The timestamp can be applied to

This article describes how QoS attributes are handled on tap ports as of EOS 4.20.5F. Prior to EOS 4.20.5F, QoS

The Tap Aggregation timestamping feature supports both timestamping packets in TAI (International Atomic Time)

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.
