+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).
