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
together with the port mirror feature, explained in Chapter 27, "Port
Mirror" on page 459.
The SRC_IPADDRESS and DST_IPADDRESS parameters specify the
source and destination IPv4 addresses. Choose from the following
options:
 any— Matches any IPv4 address.

ipaddress/mask— Matches packets that have an IPv4 address of a
subnet or an end node. The mask is a decimal number that
represents the number of bits in the address, from left to right, that
constitute the network portion of the address. For example, the
subnet address 149.11.11.0/24 has a mask of "24" for the first
twenty-four bits of the network portion of the address. The IPv4
address and the mask are separated by a slash (/); for example,
"149.11.11.0/24."
 host ipaddress— Matches packets with a specified IPv4 address
and is an alternative to the IPADRESS/MASK variable for
addresses of end nodes. The HOST keyword indicates that the
address is of a specific end node and that no mask is required.
The VLAN parameter determines if an ACL filters VLANs. You use the
parameter to specify the VID. You can specify one VID per command. If
you omit this parameter, the ACL applies to all traffic. In other words, no
filtering is done by the ACL based on the VLAN.
In the following example, a Numbered IPv4 ACL is created with an ID
number of 3000, that blocks all untagged ingress ICMP packets with a
source address of 192.168.1.10/32:
