Figure 2-2 Collapsed Backbone Meeting Room With eight 1000 Mbps parallel bridging ports (i.e., eight distinct collision domains), this switch can function as an efficient bridged node that is ideal for a meeting room e...

Network Planning 2-4 2 Making VLAN Connections The switch supports VLANs that can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more secur...

Application Notes 2-5 2 Application Notes 1. Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode. 2. For network applications t...
