A QoS Policy-maps policer is said to be shared when “set-policer” action is present under the qos features ( qos ip, qos ipv6, qos mac ) of a TCAM profile. When such shared QoS policy-map with policer action is configured on multiple interfaces, the policer instance is shared among all the interfaces, the policy-map is applied on. If in case, a unique policer instance is required per interface, a duplicate policy-map needs to be created for each interface, which will require additional TCAM resources.
