Configuring a Standard ACL
Command Attributes
• Action – An ACL can contain any combination of permit or deny rules.
• Address Type – 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)
• IP Address – Source IP address.
• Subnet Mask – 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.
