Hi Team,
I have a scenario where I'd like to fill up the N7010 CAM table using Kali Linux. Kali is installed on my macbook air as a VM and i've bridged the interface to provide my VM access to the nic. When i use macof to generate tonnes of traffic from numerous src mac/dst mac, src ip/dst ip, i do not see anything in the mac address table on the N7010 (SUP2E). But i do see traffic entering the port when i take a look at the statistics. 4000pps at approx 5mbps. So i know traffic is coming in.
All i saw on the mac address table was my physical mac nic, and my VM nic. Nothing else from the packets/frames generated by my VM.
Is it that nxos is using conversational mac learning - is this by default, or is it off?
I tried to see if I could see the traffic being broadcast on other ports in the same vlan, but tcpdump showed nothing, just usual cdp/stp from the switch.
I did the very same test on a Cisco 3560, and i was able to fill up the CAM table.
Is there a difference in the way these devices/asics handle such frames?
