This allows packets in a data stream to arrive in the same order they were sent A trunk connection can be made with any other switch that maintains host to host data streams over a single trunk port trunk connection cannot be made with switches that perform load balancing on a per packet basis VLAN VLANs a collection of switch ports grouped together in a secure autonomous broadcast and multicast domain VLANs allow a network to be segmented in order to reduce the size of broadcast domains Ethernet packets unicast broadcast multicast unknown etc entering a VLAN will only be forwarded to the ports that are members of that VLAN Another benefit of VLANs is that you can change the network topology without physically moving stations or changing cable connections Stations can be moved simply by changing 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 VLANs can also provide a level of security to your network Port based VLANs allow you to configure ports to not send or receive packets outside of the VLAN The untagging feature of IEEE 802 1Q VLANs allow VLANs to work with legacy switches and NICs that don t recognize VLAN tags in packet headers The tagging feature allows VLANs to span multiple 802 1Q compliant switches through a single physical connection and allows Spa
