Overview:

Data received by a Gigabit Switch Router (GSR) can be divided into two broad categories. First one is traffic that passes through the router via the forwarding path and second traffic that must be sent via the receive path to the GRP for further analysis. " In normal operations, the vast majority of traffic simply flows through a GSR en route to other destinations. This paper describes a new security feature called receive Access Control Lists (rACLs) and presents recommendations and guidelines for rACL deployments. Receive ACLs are used to increase security on Cisco 12000 routers by protecting the router's GRP from unnecessary and potentially nefarious traffic.
