Parameters

acl ipv4-acl-number: Specifies an IPv4 ACL by its number. For an IPv4 basic ACL, the value range is

Usage guidelines
NetStream filtering uses an ACL to identify intended packets.
• If you want to collect data for specific flows, use the ACL permit statements to identify the flows.
NetStream collects data only for these flows.
• If you do not want to collect data for specific flows, use the ACL deny statements to identify the
flows. NetStream does not collect data for these flows.
Examples
# Use ACL 2003 for outbound NetStream filtering on GigabitEthernet 1/0/1.
