enabling netflow in cisco 2960 and 4948 switches

Hi all,

I am unable to input the command "ip flow-cache timeout active 1" to my cisco 2960 and 4948 switches. But i am able to do so in my cisco 6500 series switch. Hence how do i enable netflow on both 2960 and 4948 devices?

My 2960 and 4948 are L3 switches. Pls advise what commands or additional hardware module are required. Thks in advance.

Both switches don't support Netflow as of the feature-navigator. So probably you're out of luck with that.

The 2960 is layer 2 so it won't do netflow. The 4948 does not support it. I had tried to configure it on a 3560 and although it took my commands netflow would not work. I instead had to use my asa 5520.

Is Netflow via SNMP an option on switches?

According to this Cisco doc, it appears possible.

Neither the Catalyst 2960 nor the 4948 will provide Netflow data. Please see manageengines' site for a good summary of which Cisco devices provide Netflow data.

Hi,

Hi,

Seems like depending of the IOS, a 2960 switch is able to report NetFlow.
