lists IP address and wildcard bit examples.
Each individual IP address can be configured to be permitted or denied access.
Order of Entries
The order of the entries in the list is important. The entries in the list are tested sequentially, and the
action is determined by the first entry that matches the connecting IP address. Therefore, when the entry
“any” appears in an Access Control List, all succeeding entries are irrelevant.
Consider two hypothetical ACLs containing the same entries in a different order.
The following list would permit access to all IP addresses, including 10.1.1.0:
permit any
deny 10.1.1.0
Note that the above list could not actually be created using the setup utility, since after the “any” entry,
no other entries could be added to the list. The following list will deny access to IP address 10.1.1.0, but
permit access to all others:
deny 10.1.1.0
permit any
If no entry in the assigned Access Control List matches the connection, or if the Access Control List is
empty, the default action is
deny
.
