To many interfaces than i need..

Hallo,

our customers are connected like this:

Customer Side (VRF-Interfaces) Our MPLS-Network
LAN-Interface (1 to 2 * FastEthernet) <= PE-ROUTER => 1 to 4* WAN-Interfaces

We are switched on Netflow accounting on the LAN-Interfaces:

IP Flow ingres
IP Flow engres

On the WAN-Interfaces no Netflow ist configured (netflow on MPLS-Interfaces is not supported)

Now i see in the NetFlowanalyzer all Interfaces of the Router and i have problems with the performance of the Server (High CPU). (200 Router with 2 - 6 Interfaces => 1.000 Interfaces in the Tool!!)

Can i switch the WAN-Interfaces to unmanged state? I only need the Data from the LAN-Interfaces - on the WAN-Interfaces I see the same redundant Data (there are only session from the LAN-side to the WAN-side). With this configuration "only" 300 Interfaces are configured.

Thanks

Tom
