Syntax

[no] {permit deny} {any source bitmask host source}

•any – Any source IP address.

•source – Source IP address.

•bitmask – Decimal number representing the address bits to match.

•host – Keyword followed by a specific IP address.

Default Setting

None

Command Mode

Standard ACL

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.
