Usage Guidelines You can apply named or numbered standard or extended IP access lists to an interface. To define an
access list by name, use the ip access-list global configuration command. To define a numbered access
list, use the access list global configuration command. You can used numbered standard access lists
ranging from 1 to 99 and 1300 to 1999 or extended access lists ranging from 100 to 199 and 2000 to
2699.
You can use this command to apply an access list to a Layer 2 interface. However, note these limitations
for port ACLs:
•
•
•
•
You can use input port ACLs and VLAN maps on the same switch. However, a port ACL takes
precedence over a VLAN map. When both an input port ACL and a VLAN map are applied, incoming
packets received on ports with the port ACL applied are filtered by the port ACL. Other packets are
filtered by the VLAN map.
