Egress V4 RACL scale optimization

This feature optimizes the utilization of hardware resources by sharing tcam entries for a group of SVIs on which an Ipv4 Egress Router ACL is applied. The entries will be shared for all SVIs per chip. This can save a lot of hardware resources and enables RACLs to scale to larger configurations. Deployments where Ipv4 egress RACLs are applied on multiple SVIs with member interfaces on same forwarding ASIC, will benefit from this feature. For example, a trunk port carrying multiple vlans and and an egress RACL applied on all vlans will occupy lesser tcam space irrespective of number of vlans. Platform...

RACL divergence

RACL divergence enables the optimization of the utilization of hardware resources by installing ACLs only on the hardware components corresponding to the member interfaces belonging to the SVIs on which the ACL is applied. This can save a lot of hardware resources and enables RACLs to scale to larger configurations. Deployments where multiple large RACLs are applied on SVIs with member interfaces corresponding to mutually exclusive forwarding ASICs, will benefit from this feature. Terminology RACL : any access-Lists (ACL) applied to an Switched Virtual Interface (SVI). Ingress traffic : any traffic entering a VLAN is said to ingress the SVI corresponding to the VLAN Egress...
