+description: |
+ The Lan966x Enterprise Ethernet switch family provides a rich set of
+ Enterprise switching features such as advanced TCAM-based VLAN and
+ QoS processing enabling delivery of differentiated services, and
+ security through TCAM-based frame processing using versatile content
+ aware processor (VCAP).
