Purpose
Enters the global configuration mode.
Enters interface configuration mode and configures an interface.
Command parameters for the interface configuration include:
You cannot attach a NetFlow monitor to a port channel interface. If both
service module interfaces are part of an EtherChannel, you should attach
the monitor to both physical interfaces.
Associate an IPv4 or an IPv6 flow monitor, and an optional sampler to
the interface for input or output packets.
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
Note
configure a sampler. If the sampler is missing, you will receive
an error message.
Returns to privileged EXEC mode.
