log-input
—Specifies sending an informational syslog message about the
packet that matches the entry. Because forwarding is done in hardware
and logging is done in software, if a large number of packets match a deny
ACE containing a log-input keyword, the software might not be able to
match the hardware processing rate, and not all packets will be logged.
Default
No IPv4 access list is defined.
Command Mode
IP Access-list Configuration mode
User Guidelines
You enter IP-access list configuration mode by using the IP Access-list Global
Configuration command.
After an access control entry (ACE) is added to an access control list, an
implied deny any any condition exists at the end of the list. That is, if there
are no matches, the packets are denied. However, before the first ACE is
added, the list permits all packets.
The number of TCP/UDP ranges that can be defined in ACLs is limited. You
can define up to #ASIC-specific ranges for TCP and up to #ASIC-specific
ranges for UDP. If a range of ports is used for source port in ACE it would be
not be counted again if it is also used for source port in another ACE. If a
range of ports is used for destination port in ACE it would be not be counted
again if it is also used for destination port in another ACE.
If a range of ports is used for source port, it would be counted again if it is also
used for destination port.
Example
console(config)# ip access-list extended server
console(config-ip-al)#
deny
ip 1.1.1.0 0.0.0.255 1.1.2.0 0.0.0.0
