Port Information

The port information is optional. To compare the source and destination ports, use the eq (equal) option,
the gt (greater than) option, the lt (less than) option, or the range (range of ports) option. You can specify
the port information in one of two ways:

Using the 32-bit quantity in four-part, dotted decimal format (10.1.1.2/0.0.0.0 is the same as host
10.1.1.2).
Each wildcard bit set to zero indicates that the corresponding bit position in the packet's ip
–
address must exactly match the bit value in the corresponding bit position in the source.
Each wildcard bit set to one indicates that both a zero bit and a one bit in the corresponding
–
position of the packet's ip address will be considered a match to this access list entry. Place ones
in the bit positions you want to ignore. For example, 0.0.255.255 to require an exact match of
only the first 16 bits of the source. Wildcard bits set to one do not need to be contiguous in the
source-wildcard. For example, a source-wildcard of 0.255.0.64 would be valid.
Using the any option as an abbreviation for a source and source-wildcard or destination and
destination-wildcard (0.0.0.0/255.255.255.255)
