Chapter 8: 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 inter-switch links.
Use the VLAN feature to partition a single IntraCore 3724PWR 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 ?
add Create a new VLAN
delete Remove a existed VLAN
port Configure 802.1Q port parameters for VLANs
lag Configure lag to a special VLAN
Switch(Config)# interface 4
Switch(Interface 4)# vlan ?
participation Join or leave a VLAN
protected Configure port protected property
dropnq Configure port drop no 8021q frame
ingress Configure port filter
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 3724PWR. 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
.
8.1 Creating or Modifying a VLAN
To create a VLAN with id 2, enter the following commands beginning in enabled mode:
Switch#
Switch# configuration
Switch(Config)# vlan
add Create a new VLAN
delete Remove a existed VLAN
port Configure 802.1Q port parameters for VLANs
lag Configure lag to a special VLAN
Switch(Config)# vlan add
