About QoS TCAM Lite Regions

IPV4 requires QoS TCAM regions to be double wide TCAMs to support conform/violate policer statistics.
If conform/violate statistics are not required, the size of the QoS TCAM entries can be reduced to single wide
TCAMs by using QoS TCAM lite regions. Policing is supported by these regions, however only violate
packets/bytes statistics are supported.
Purpose
QoS policy applied on Layer 2
interfaces.
QoS policy applied on VLAN.
QoS policy applied on FEX
interfaces.
