Port Trunking
Another performance enhancing feature of the SmartSTACK ELS100-16TX is Port Trunking. The SmartSTACK ELS100-16TX allows two Trunk groups of up to eight 10 Mbps or 100 Mbps ports to be connected between the SmartSTACK ELS100-16TX and network devices including Cabletron’s SmartStack 10, FastNET products and ATX LAN switch. This capability provides a scalable dedicated bandwidth in a single trunk group of up to 1.6 Gbps (full duplex) when using 100BaseX ports or 160Mbps (full duplex) when using the ports in 10BaseT mode. This is accomplished without introducing any emerging technologies such as Gigabit Ethernet or ATM. By connecting multiple SmartSTACK ELS100- 16TX products using port trunking, the network administrator can create a virtual chassis (spanning multiple physical chassis), providing many-switched Ethernet and Fast Ethernet ports at a very low cost per port.
Autonegotiation
Auto-negotiation is supported on all of the 16 switched Ethernet
