This is useful in cases where an sFlow collector does not recognize Tag Type 1991. In these
situations, the Tag Type 1991 samples can be ignored without disrupting the sFlow sequence
numbers. It is also useful for indentifying samples obtained using ACL-based sFlow that you might
want to perform other processes.

Configuring ACL-based inbound sFlow
The followings sections describe how to configure ACL-based Inbound sFlow:

•
“Specifying an sFlow collector”
Configuration considerations for ACL-based inbound sFlow
Consider the following when you configure ACL-based inbound sFlow:
•
sFlow must be enabled on the router.
•
ACL-based mirroring: The mirror and copy-sflow keywords are mutually exclusive on a per ACL
clause basis.
•
Port-based monitoring: Port-based monitoring and ACL-based sFlow can co-exist on the same
interface.
•
Port-based sFlow: Port and ACL-based sFlow can co-exist on the same interface. When both
features are configured on an interface, packets that qualify as ACL-based sFlow packets are
sent to the collector as ACL sample packets. Also, the user can configure ACL-based sFlow on
an interface without configuring port-based sFlow.
