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.

This command adds a rule to an Extended IP ACL. The rule sets a

filter condition for packets with specific source or destination IP

addresses, protocol types, source or destination protocol ports, or TCP

control codes. Use the no form to remove a rule.

Syntax

[no] {permit | deny} [protocol-number | udp]

{any | source address-bitmask | host source}
