Odom,Wendell-_CCNA_200-301_Official_Cert_Guide,_Volume_1.pdf :
many SOHO Ethernet LANs today combine the router and switch into a single device. Vendors sell consumer-grade integrated networking devices that work as a router and Ethernet switch, as well as doing other functions. These devices typically have “router” on the packaging, but many models also have four-port or eight-port Ethernet LAN switch ports built in to the device.
When choosing between straight-through and cross-over cables should I treat those integrated networking devices frequently called routers as of the same type as PC's NIC (or router) or of the type of switch?
I am aware that the presence auto-mdix in such devices may diminish the importance of the cable choice. But let this be outside of the scope of the question.
