The egress port ACL will not match packets if the destination port is a trunk member. Summary of ACL actions Actions determine how the traffic is treated. The GbE2c QoS actions include the following: • Pass or Drop • Re-mark a new DiffServ Code Point (DSCP) • Re-mark the 802.1p field • Set the COS queue Understanding ACL precedence Each ACL has a unique precedence level, based on its number. When an incoming packet matches the highest precedence ACL, the ACL's configured action takes place. The other assigned ACLs also are considered, in order of precedence. ACLs are divided into Precedence Groups, as shown in the following table. Each Precedence Group provides a different set of packet classifiers for the ACLs within the Precedence Group.
