Associate an IPv4 or an IPv6 flow monitor, and an optional sampler to
the interface for input or output packets.
{ip flow monitor | ipv6 flow monitor}name
[|sampler name] { input |output }
Step 3

Switch(config-if)# ip flow monitor
To monitor datalink L2 traffic flows, you would use datalink flow
monitor name sampler sampler-name {input} interface command. This
specific command associates a datalink L2 flow monitor and required
sampler to the interface for input packets. When a datalink flow monitor

is assigned to an interface or VLAN record, it only creates flows for
non-IPv6 or non-IPv4 traffic.
Whenever you assign a flow monitor to an interface, you must
configure a sampler. If the sampler is missing, you will receive
an error message.
