Fast Ethernet Switching System User's Guide VLAN Port Management The VLAN Port Management Menu, shown in Figure 61, enables you to create, delete and modify VLANs. A Virtual Local Area Network (VLAN) is a logical subgroup within a LAN that is created with software rather than physical connections. The purpose of a VLAN is to prevent broadcast storms and ease congestion on the network. Each VLAN created is a broadcast domain. A broadcast is a packet that is sent to all nodes on the network. A broadcast domain is a domain in which every node in the domain receives the broadcast packet. The advantage of creating VLANs is that they permit you to group LAN segments together in order to get the most out of your network. VLANs become more important as the network grows and traffic increases. VLANs are usually used on high traffic networks. You should consider a VLAN on a smaller network if a department or workgroup routinely does tasks that take up a lot of bandwidth and they are not already on their own LAN segment. VLANs can be used to subdivide the network. The DES-5600 supports port based VLAN. Port based VLAN means that the VLAN is grouped by port. If a VLAN is created using three ports, then those ports become a separate broadcast domain. By using VLANs, members of a particular department or workgroup can be partitioned from the rest of the network. For example, the marketing department can be on one VLAN and the accounting department can be on another. If a workstation in marketing sends a broadcast packet to another workstation in marketing the packet will remain on the marketing VLAN. Create VLAN/ Modify VLAN The Create VLAN panel, shown in Figure 61, enables you to create VLAN by selecting specific ports as part of a VLAN. The default value is that all ports belong to one VLAN. You can create up to eight separate VLANs. Ports can belong to two VLANs at the same time. Each VLAN is a broadcast domain. If you have created a trunking group, you must include the entire trunk group in the VLAN. Delete VLAN Deletes VLANs in their entirety. Web Management 105

VLAN Port Management
The VLAN Port Management Menu, shown in Figure 61, enables you to create,
delete and modify VLANs. A Virtual Local Area Network (VLAN) is a logical
subgroup within a LAN that is created with software rather than physical
connections. The purpose of a VLAN is to prevent broadcast storms and ease
congestion on the network.
Each VLAN created is a broadcast domain. A broadcast is a packet that is sent to
all nodes on the network. A broadcast domain is a domain in which every node in
the domain receives the broadcast packet. The advantage of creating VLANs is
that they permit you to group LAN segments together in order to get the most out
of your network.
VLANs become more important as the network grows and traffic increases.
VLANs are usually used on high traffic networks. You should consider a VLAN
on a smaller network if a department or workgroup routinely does tasks that take
up a lot of bandwidth and they are not already on their own LAN segment.
VLANs can be used to subdivide the network. The DES-5600 supports port based
VLAN. Port based VLAN means that the VLAN is grouped by port. If a VLAN is
created using three ports, then those ports become a separate broadcast domain.
By using VLANs, members of a particular department or workgroup can be
partitioned from the rest of the network. For example, the marketing department
can be on one VLAN and the accounting department can be on another. If a
workstation in marketing sends a broadcast packet to another workstation in
marketing the packet will remain on the marketing VLAN.
Create VLAN/ Modify VLAN
The Create VLAN panel, shown in Figure 61, enables you to create VLAN by
selecting specific ports as part of a VLAN. The default value is that all ports
belong to one VLAN. You can create up to eight separate VLANs. Ports can
belong to two VLANs at the same time. Each VLAN is a broadcast domain. If
you have created a trunking group, you must include the entire trunk group in the
VLAN.
