    An access list is a sequential collection of permit and deny conditions that apply to IP addresses. The Cisco IOS software tests addresses against the conditions in an access list one by one. The first match determines whether the software accepts or rejects the address. Because the software stops testing conditions after the first match, the order of the conditions is critical.
  • Page 155 However, the current implementation of access lists is incompatible with Cisco IOS Release 11.1 or earlier. If you create an access list using the current Cisco IOS release and then load older Cisco IOS software, the resulting access list will not be interpreted correctly.
