Chapter 25 Configuring Network Security with ACLs
Using VLAN Maps with Router ACLs
ACLs and Bridged Packets
Figure 25-7 shows how an ACL is applied on fallback-bridged packets. For bridged packets, only
Layer 2 ACLs are applied to the input VLAN. Only non-IPv4, non-ARP packets can be fallback-bridged.

ACLs and Routed Packets
Figure 25-8 shows how ACLs are applied on routed packets. For routed packets, the ACLs are applied
in this order:
1. VLAN map for input VLAN
2. Input router ACL
3. Output router ACL
4. VLAN map for output VLAN
