Virus Throttling (Connection-Rate Filtering)
Configuring and Applying Connection-Rate ACLs
ip-addr < mask-length >: Applies the ACEs action (filter
or ignore) to IP traffic having an SA within the range
defined by either:
< src-ip-addr/cidr-mask-bits>
or
<src-ip-addr < mask >>
Use this criterion for traffic received from either a
subnet or a group of IP addresses. The mask can be in
either dotted-decimal format or CIDR format with the
number of significant bits. Refer to “Using CIDR
Notation To Enter the ACE Mask” on page 3-25.
