For IPv4 ACLs, configure these parameters:
•
Protocol—The Protocol field to use an Layer 3 or Layer 4 protocol match
condition based on the value of the IP Protocol field in IPv4 packets or the
Next Header field in IPv6 packets.
condition based on the value of the IP Protocol field in IPv4 packets or the

If you select Protocol, select one of these options:
-
Select From List—Select one of these protocols: IP, ICMP, IGMP, TCP, or
UDP.
UDP.
-
Match to Value—Enter a standard IANA-assigned protocol ID from
0 to 255. Choose this method to identify a protocol not listed by name in
the Select From List.
0 to 255. Choose this method to identify a protocol not listed by name in

•
Source IP Address—Requires a packet's source IP address to match the
address listed here. Enter an IP address in the appropriate field to apply this
criteria.
address listed here. Enter an IP address in the appropriate field to apply this
criteria.
•
Wild Card Mask—The source IP address wildcard mask.
The wildcard mask determines which bits are used and which bits are
ignored. A wildcard mask of 255.255.255.255 indicates that no bit is
important. A wildcard of 0.0.0.0 indicates that all bits are important. This field
is required when Source IP Address is checked.
ignored. A wildcard mask of 255.255.255.255 indicates that no bit is
important. A wildcard of 0.0.0.0 indicates that all bits are important. This field
is required when Source IP Address is checked.
A wildcard mask is basically the inverse of a subnet mask. For example, to
match the criteria to a single host address, use a wildcard mask of 0.0.0.0. To
match the criteria to a 24-bit subnet (for example, 192.168.10.0/24), use a
wildcard mask of 0.0.0.255.
