Configuring a Standard IP ACL
Command Attributes
• Action – An ACL can contain all permit rules or all deny rules.
(Default: Permit rules)
• IP – Specifies the source IP address. Use “Any” to include all possible
addresses, “Host” to specify a specific host address in the Address field,
or “IP” to specify a range of addresses with the Address and SubMask
fields. (Options: Any, Host, IP; Default: Any)
• Address – Source IP address.
• SubMask – A subnet mask containing four integers from 0 to 255, each
separated by a period. The mask uses 1 bits to indicate “match” and 0 bits
to indicate “ignore.” The mask is bitwise ANDed with the specified
source IP address, and compared with the address for each IP packet
entering the port(s) to which this ACL has been assigned.
