flow monitor m1
! monitor refers record configuration and optionally exporter
! configuration. It specifies the cache size i.e. how many unique flow
! records to collect
record r1
exporter e1
cache timeout active 60
cache timeout inactive 30
cache entries 1000

2. Flow collection is supported on multiple targets (Port, VLAN, per-port per-VLAN (FNF can be
enabled on a specific VLAN on a given port)) and on a port-channel (FNF is configured on the
port-channel interface, rather than individual member ports).
3. 64 unique flow record configurations are supported.
4. Flow QoS/UBRL and FNF cannot be configured on the same target. (For information on Flow-based
QoS, see the section Flow-based QoS, page 44-10.)
5. 14,000 unique IPv6 addresses can be monitored.
6. On a given target, one monitor per traffic type is allowed. However, you can configure multiple
monitors on the same target for different traffic types.
For example, the following configuration is allowed:
! vlan config 10
ip flow monitor <name> input
ipv6 flow monitor <name> input
!
The following configuration is not allowed:
!
interface GigabitEthernet 3/1
ip flow monitor m1 input
ip flow monitor m2 input
7. On a given target monitoring Layer 2 and Layer 3, simultaneous traffic is not supported:
interface channel-group 1
datalink flow monitor m1 input
ip flow monitor m2 input
!
8. Selection of Layer 2 and Layer 3 packet fields in a single flow record definition is disallowed.
However, ingress 802.1Q VLAN Id of packet and Layer 3 packet field selection is allowed.
9. To attach a monitor to port or port-vlan targets, a flow record matching on ingress 802.1Q VLAN Id
as the key field, must also match on the input interface as the key field.
