We have recently enabled netflow on one of our Cisco 7609 routers with a Sup720 3BXL supervisor card. I am running the capture on a 10Gb transit link with around 1.5G of traffic at peak. The TCAM table is constantly showing at 100% used and I would like to know if anyone has any ideas of how to get the usage down.
