If there is a switching circuit in the hub (or in any hub in a stack), it will serve as a bridge between the two repeaters. 10Mbps Repeater Switching Circuit 100Mbps Repeater NWay Detection RJ-45 Ports 100Mbps Ethernet Station 100Mbps Ethernet Station 10Mbps Ethernet Station 10Mbps Ethernet Station 100Mbps Ethernet Station The switching circuit does not, however join the 10Mbps Ethernet collision domain with the 100Mbps Fast Ethernet collision domain; it only allows them to communicate. The two repeaters are two separate collision domains regardless of whether a switching circuit is present. If a DFE-2600 series hub or hub stack is uplinked through a twisted-pair or Uplink port to another dual-speed or Fast Ethernet hub or stack, the hub will function as a Class II Fast Ethernet device and be subject to those connectivity rules. If it is uplinked to a 10BASE-T Ethernet hub or stack (10Mbps only) then it will function as a normal 10BASE-T Ethernet repeater and is then subject to those connection rules. And because it is a dual-speed hub with two separate repeaters, it can connect to both at the same time, counting as a repeater in each of the collision domains. For more detailed information, please refer to Chapter 4, Making Connections. Introduction 5
