Does a switch have the ability to send IP addresses?

Answer Posted / john robbins

Depends whether or not the "switch" is a layer2 only, or
layer 2/3 capable. Some switches these days can perform
routing, run IGPs such as OSPF, etc. - for these with
layer3 capabilily and DHCP, you can create loopback IP's to
source a packet, such as for 802.1x authentication. For
traditional switches, layer2 only, packets are broadcast
with IP addresses (source/destination) simply passed
through - entire frames are "switched" based on MAC address
(layer2) with no layer3 lookup/routing.
