Specifying Netflow Table Entry Creation On A Per-Interface Basis - Cisco WS-C6506 Software Manual

Configuring the NetFlow Statistics on the Switch

Specifying NetFlow Table Entry Creation on a Per-Interface Basis

Note This feature requires PFC3B, PFC3BXL or later.
With software release 8.4(1) and later releases, you can create the NetFlow table entries on a
per-interface basis. This feature uses the same mechanism as the bridged-flow statistics to create flows.
The NetFlow entries are created for both VLANs on which the bridged-flow statistics are enabled and
on the VLANs on which NetFlow entry creation is enabled (see the
Bridged-Flow Statistics on VLANs" section on page
For example, if you enable the Layer 3 per-interface entry creation on VLAN 100 and 200 and at the
same time you want to enable the bridged-flow statistics on VLAN 150 and 250, the NetFlow entry and
the bridged-flow statistics are enabled on all four VLANs. To specify only the bridged-flow statistics for
VLAN 150 and 250, you must disable the per-interface entry feature.
In addition, the bridged-flow statistics are automatically enabled when you enable the NetFlow entry
creation on a per-interface basis for VLANs. The CLI allows you to disable NetFlow per interface if you
do not want this overlap in the Netflow table entry creation.
The status of this feature is displayed as part of the show mls command. The VLANs that have entry
creation enabled are displayed as part of the VLANs that have the bridged-flow statistics feature enabled.
To enable or disable the NetFlow per-interface table entries, perform this task in privileged mode:
Task
Enable the NetFlow per-interface table entries.
This example shows how to enable the NetFlow per-interface table entries:
Console> (enable) set mls netflow-per-interface enable
Console> (enable)
You can specify the VLANs for which the NetFlow entries can be enabled or disabled. To control the
flow creation on a VLAN basis, perform this task in privileged mode:
Task
Enable the per-VLAN NetFlow table entries.
This example shows how to specify the VLANs that are used to create the NetFlow table entries:
Console> (enable) set mls netflow-entry-create enable 150, 250
Console> (enable)
