Switch Memory issue due to Netflow

Netflow is the mechanism through which we can capture the real time data of the network to analyse the traffic pattern , Bandwidth usage and to troubleshoot the utilization of the network .

Some time Netflow cause the Memory utilization causing switch to go in romman mode .

When switch goes in romman mode it gives the following error :

Sep 26 13:26:00.113 UTC: %EARL_NETFLOW-SP-4-TCAM_THRLD: Netflow TCAM threshold exceeded, TCAM Utilization [99%]

To solve this we need to configure the following :

Core-Switch(config)#no mls flow ip interface-full
Core-Switch(config)#mls flow ip interface-destination-source
