Description
This feature was introduced on the Cisco 10000 series
router.
A receive ACL must be a numbered ACL. You cannot use a named ACL as the receive ACL.
The rules for numbered ACLs also apply to the access control entries (ACEs) of receive ACLs.
Time-based and reflexive ACLs are not supported as receive ACLs.
Only traffic processed by the RP is filtered. Traffic that is processed exclusively by the Forwarding
Processor (FP) is not filtered. For example, GRE tunneled packets, L2TP tunneled packets, and
some ICMP packets are not filtered.
