The following example configures two Numbered IPv4 ACLs. ACL 3017
permits packets from TCP port 67 to 87 on IPv4 addresses 154.11.234.0/
24 to 154.11.235.0/24. ACL 3005 denies packets from TCP ports 67
through 87 to any IPv4 address. This example requires a permit ACL
because the permitted traffic is a subset of all TCP packets on the port:
Numbered IPv4 ACL with UDP Port Packets Example
access-list
id_number action
udp
src_ipaddress
eq|lt|gt|ne|range
src_udp_port dst_ipaddress
eq|lt|gt|ne|range
dst_udp_port
vlan
vid
The ID_NUMBER parameter assigns the ACL a unique ID number in the
range of 3000 to 3699. Within this range, you can number ACLs in any
order.
The ACTION parameter specifies the action that the port performs on
packets matching the filtering criteria of the ACL. Here are the possible
actions:
permit— Forwards all ingress packets that match the ACL. Ports,
by default, accept all ingress packets. Consequently, a permit ACL
is only necessary when you want a port to forward a subset of
packets that are otherwise discarded.
deny— Discards all ingress packets that match the ACL.
copy-to-mirror— Copies all ingress packets that match the ACL to
the destination port of the mirror port. This action must be used

154.11.234.0/24 to 154.11.235.0/24.
awplus(config)# access-list 3005
deny tcp any any range 67 87
Define ACL 3005 to deny packets from TCP
ports 67 through 87 to any IPv4 address.
awplus(config)# interface port1.0.21 Move to the Port Interface mode for port 21.
awplus(config_if)# access-group 3017 Apply ACL 3017 to the port with the
ACCESS-GROUP command.
awplus(config_if)# access-group 3005 Apply ACL 3005 to the port with the
ACCESS-GROUP command.
