A service of IET
A Virtual Local Area Network (VLAN) facilitates "localized" routing and resource sharing capability for any computer on the campus network even if they are not located in the same physical location. By using MultiVLAN, campus departments can decrease the number of network connections (and the associated costs) needed to support servers and firewalls that span multiple VLANs.
- Enables computers in different locations to send and receive network messages
- Increases performance, manageability and security of computers, servers and firewalls
- Order up to 6 VLANs for a single data connection
- MultiVLANs reduce the number of NAMs required for firewalls and servers.
- The MultiVLAN feature cannot be used with Wireless Access Points (WAPs) or DSL.
Each department on campus has an Authorized Telecommunications Representative (ATR) that is responsible for communications services. ATRs can access service request forms to order/change/disconnect telecommunications services, and download electronic telecommunications statements.
Customer service is available Mon-Fri, 8am-noon & 1-5pm (closed noon-1pm).
What is a VLAN?
A Virtual Local Area Network is a computer network that is usually connected to localized routers and computing resources to send and receive network messages. It facilitates "localized" routing and resource sharing capability for any computer on the campus network even if they are not located in the same physical location. The benefits of VLAN technology include increased performance, improved manageability and increased security.
The term "tag" or "VLAN tag" is used to describe the devices employed by VLAN technology. The IEEE 802.1Q protocol describes "VLAN tagging" - the use of "tags" as unique identifiers in the MAC address header. Packets with this extra tag are routed to the correct VLAN destination through the campus core network. If a network device such as a server or firewall must interpret network traffic from several (up to 6) VLANs to fulfill its function, it can be connected to a single MultiVLAN-enabled NAM and receive packets destined for 6 VLANs.
