Tap Aggregation – QinQ Identity Tagging

Identity tagging is an existing Tap Aggregation feature that allows a 802.1Q header to be added to packets sent by tool ports with a configurable identity value. This article describes a feature to enable QinQ identity tagging, allowing two 802.1Q headers to be added. Platform Compatibility DCS-7280R/R2 series DCS-7500R/R2 series Frame Format The first 802.1Q header is called the “outer” header, and the second 802.1Q header the “inner” header. Configuration To enable QinQ identity tagging, a user-defined TCAM profile must be also configured. The following commands configure the user-defined TCAM profile tap-aggregation-user-qinq, based on the existing TCAM profile tap-aggregation-extended. 7500(config-hw-tcam)#profile...
