If you're connected to a switch and your NIC is in promiscuous mode, what traffic would you be able to capture
If you're connected to a switch and your NIC is in promiscuous mode, the traffic would you be able to capture would be broadcast traffic.
What is Broadcast traffic?
Broadcast traffic is used to send packets to all hosts on the network using the network's broadcast address. With a broadcast, the packet contains a destination IP address that only has numbers one (1s) in the host portion. This means that all hosts on that local network (broadcast domain) will receive and verify the packet. Many network protocols, such as DHCP, use broadcasts. When a host receives a packet sent to the network's broadcast address, the host processes the packet as a packet addressed to its unicast address.
Also, there are two types of broadcasts: directed broadcast and limited broadcast.
