  • Page 30: Vlans And Broadcast Domains

    24-port NWay Ethernet Switch User’s Guide Figure 5-3. Port trunking example The switch treats all ports in a trunk group as a single port. As such, trunk ports will not be blocked by Spanning Tree. Data transmitted to a specific host (destination address) will always be transmitted over the same port in a trunk group.

  • Page 31: Mac-Based Broadcast Domains

    24-port NWay Ethernet Switch User’s Guide communicate with its members and share its resources, simply by changing the port VLAN settings from one VLAN (the sales VLAN, for example) to another VLAN (the marketing VLAN). This allows VLANs to accommodate network moves, changes and additions with the utmost flexibility. MAC-based broadcast domains, on the other hand, allow a station to be physically moved yet still belong to the same broadcast domain without having to change and configuration settings.

    24-port NWay Ethernet Switch User’s Guide Figure 5-5. Data transmissions between 802.1Q-compliant Switches In the above example, step 4 is the key element. Because the packet has 802.1Q VLAN data encoded in its header, the ingress port can make VLAN-based decisions about its delivery: whether server #2 is attached to a port that is a member of VLAN 2 and thus, should the packet be delivered;...

  • Page 35: Broadcast Storms

    However, with the advent of VLANs, switches are now able to limit broadcast domains better and cheaper than routers. Also, many switches, including the DES-3225G series, have broadcast sensors and filters built into each port to further control broadcast storms.
