What L3 functionality enables a L3 switch to effectively inhibit 'sniffing' by a promiscuous NIC on one of the modes.

Is it VLANs and Trunks

I thorught VLAN's and Trunks were L2.  Is that a misunderstanding on my part ?

    Accepted Solution

    It's the functionality to determine which path to use to forward network traffic based on logical (IP) addressing, not just on physical (MAC) addressing.

    Normally a layer-3 capable switch will perform layer 3 logical adressing if it is not deliberately put into "bridge" mode.
