Chapter 7: VLAN Configuration
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
Use the VLAN feature to partition a single IntraCore 3624/48 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, and setup of tagging. The following shows the commands available to configure VLAN’s.
Switch(Config)# vlan ? | Create a new VLAN |
add | |
delete | Remove a existed VLAN |
port | Configure 802.1Q port parameters for VLANs |
lag | Configure lag to a special VLAN |

pvid | Configure port PVID |
The switch is shipped with a default VLAN with VLAN ID (VID) 1. All switch ports are included in the default VID 1. The default VID 1 cannot be deleted.
Up to 256 Virtual LANs (VLANs) are supported on the IntraCore 3624/48. The default VLAN with VLAN ID (VID) 1. All switch ports are included in the default VID 1. The default VID 1 cannot be deleted.
