Am I understanding how switches work correctly?

• ethernet

  13 270 2.7 Go

  Package ethernet implements marshaling and unmarshaling of IEEE 802.3 Ethernet II frames and IEEE 802.1Q VLAN tags. MIT Licensed.

I find looking at the header structure directly helps me to wrap my head around it. At layer 2 you are dealing exclusively with Ethernet frames which have a number of fields in their header that indicate their source and destination MAC addresses, among other things. These frames are what the switch builds it's CAM table from and it uses that table to forward traffic, and for a layer 2 switch that is the entire picture.
