Command Usage

• New rules are appended to the end of the list.
• Address bitmasks are similar to a subnet mask, containing four

integers from 0 to 255, each separated by a period. The binary mask
uses 1 bits to indicate “match” and 0 bits to indicate “ignore.” The
bitmask is bitwise ANDed with the specified source IP address, and
then compared with the address for each IP packet entering the port(s)
to which this ACL has been assigned.

Example
This example configures one permit rule for the specific address 10.1.1.21
and another rule for the address range 168.92.16.x – 168.92.31.x using a
bitmask.
