A variety of dynamic counter features, primarily configured by the [no] hardware counter feature [feature] CLI commands, may be enabled simultaneously. Compatibility of these features has been enhanced to allow for greater flexibility in simultaneously enabled counter features. 

This feature introduces the possibility of creating Tap Aggregation PMF profiles consisting of 80 bit keys, to make a more efficient use of TCAM resources. Previously, we could only have key sizes of 160 or 320 bits.

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 document describes the truncation capability for Tap Aggregation, which allows tapped traffic to be truncated to a smaller size before being transmitted.
