IPv4 Access Control Lists (ACLs)
Traffic Management and Improved Network Performance
Table 9-5.
Addr
Shaded areas indicate bit settings that must be an exact match.
If there is a match between the policy in the ACE and the IP address in a packet,
then the packet is either permitted or denied, according to how the ACE is
configured. If there is not a match, the next ACE in the ACL is then applied to
the packet. The same operation applies to a destination IP address (DA) used
in an extended ACE. (Where an ACE includes both source and destination IP
addresses, there is one IP-address/ACL-mask pair for the source address, and
another IP-address/ACL-mask pair for the destination address. See "Configur­
ing and Assigning an ACL" on page 9-33.)
CIDR Notation. For information on using CIDR notation to specify ACL
masks, refer to "Using CIDR Notation To Enter the ACL Mask" on page 9-39.
