IPv4 Access Control Lists (ACLs)

Configuring Standard ACLs

[ log]

This option generates an ACL log message if:

The action is deny.

There is a match.

ACL logging is enabled on the switch. (Refer to “” on page 9-96.)

(Use the debug command to direct ACL logging output to the current console session and/or to a Syslog server. Note that you must also use the logging < ip-addr> command to specify the addresses of Syslog servers to which you want log messages sent. See also “” on page 9-96.)

Example of Creating and Listing a Standard, Named ACL. This exam­ ple illustrates how to create a standard, named ACL with several ACEs. This example creates an ACL that:

1.permits IPv4 traffic from a host with the address of 10.10.10.104

2.creates another ACE that blocks all other IPv4 traffic from the same subnet

3.allows all other IPv4 traffic

ProCurve(config)# ip access-list standard Sample-List ProCurve(config-std-nacl)# permit host 10.10.10.104 ProCurve(config-std-nacl)# deny 10.10.10.1/24 log ProCurve(config-std-nacl)# permit any ProCurve(config-std-nacl)# exit ProCurve(config)# _

Creates the “Sample-List” ACL and enters the “Named ACL” context for this list.

Appends three ACEs to the list in the order shown.

Exits from the nacl context.
