5.5 Configuring VLAN
VLANs are used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group and eliminate broadcast storms in large networks. VLANs provide a secure and efficient network environment.
VLANs are based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs. Untagged VLANs can be used for small networks attached to a single switch. Tagged VLANs should be used for larger networks, and all the VLANs assigned to the
Using multiple spanning trees allow VLAN groups to maintain a stable path between all VLAN members. This reduces the overall amount of protocol traffic crossing the network and provides a shorter reconfiguration time if any link in the spanning tree fails
Use the VLAN feature to partition a single IntraCore IC36240 into a VLAN each containing its own set of ports. Packets are forwarded only between ports belonging to the same VLAN. This allows you to restrict access from one segment to another to increase network security or to reduce traffic. To set up VLANs you should specify the ports belonging to the VLAN, the set the IP configuration, individual access map associated with a set of VLANs and enable tagging. Once you have configured the VLAN and copied the information into the
