fragments
To optimize whether an IPv4 or IPv6 ACL permits or denies noninitial fragments that do not match an explicit
permit
or
deny
command in the ACL, use the
fragments
command. To disable fragment optimization, use
the
no
form of this command.

Usage Guidelines
The
fragments
command allows you to simplify the configuration of an IP ACL when you want to permit
or deny noninitial fragments that do not match an explicit
permit
or
deny
command in the ACL. Instead of
controlling noninitial fragment handling by using many
permit
or
deny
commands that specify the
fragments
keyword, you can use the
fragments
command instead.
When a device applies to traffic an ACL that contains the
fragments
command, it only matches noninitial
fragments that do not match any explicit
permit
or
deny
commands in the ACL.
This command does not require a license.
Examples
This example shows how to enable fragment optimization in an IPv4 ACL named lab-acl. The
permit-all
keyword means that the ACL permits any noninitial fragment that does not match a
deny
command that
includes the
fragments
keyword.
