ATM ports if supported. In Figure 3-10, the priority is “0”. The

 

selections are as follows:

 

ADD PORT – adds the port selected in the Port field.

 

ADD ALL PORTS – adds ALL PORTS that are configurable to the

 

VLAN ID shown in the VLAN ID field.

 

DELETE PORT – deletes the port selected in the Port field.

 

DELETE ALL PORTS – deletes ALL PORTS that are configurable

3.9.1Adding/Deleting Ports Associated with a VLAN ID

To add or delete ports from a VLAN, proceed as follows:

1.Use the arrow keys to highlight the Port field.

2.Press the SPACE bar to step to the appropriate port number. The associated protocol is displayed for that port.

3.Use the arrow keys to highlight the DELETE ALL PORTS field.

4.Press the SPACE bar to step to the appropriate selection to ADD PORT, ADD ALL PORTS, DELETE PORT, or DELETE ALL PORTS from the VLAN ID shown in the VLAN ID field.

5.Use the arrow keys to highlight the SAVE command at the bottom of the screen.

6.Press ENTER. The message “SAVED OK” displays and the settings are saved.

802.1Q specifications

Enterasys Networks, a subsidiary of the Siemens Group, is widely recognized for its comprehensive networking solutions, with a strong emphasis on security, reliability, and performance. One of the key technologies offered by Enterasys is 802.1Q, a critical component of Ethernet networking that establishes standards for VLAN (Virtual Local Area Network) tagging. This technology is essential for enhancing network performance and managing traffic efficiently.

The primary feature of 802.1Q is its ability to create VLANs, which segment a physical network into multiple logical networks. This segmentation improves network security by isolating sensitive data and restricting access to specific users or devices. With VLANs, organizations can reduce broadcast traffic, thereby enhancing overall network efficiency. Different departments within an organization can operate on their own VLAN, ensuring that their traffic is kept separate from others.

One significant technological aspect of 802.1Q is its tagging method. When a frame passes through a switch port configured for IEEE 802.1Q, the switch appends a VLAN tag to the frame. This tag contains important information, such as the VLAN ID, enabling switches and devices throughout the network to identify which VLAN the frame belongs to. This tagging is especially critical in environments where multiple VLANs share the same physical infrastructure.

Another characteristic of Enterasys Networks' implementation of 802.1Q is interoperability with existing network standards and protocols. This means that organizations can implement VLAN tagging without requiring major upgrades or replacements of their switch hardware. Enterasys ensures that its switches are compliant with various industry standards, making it easier for enterprises to integrate these solutions into their existing network settings.

Security is another vital feature of Enterasys Networks’ 802.1Q offering. By leveraging VLANs, organizations can enforce stricter access controls and policies, reducing the risk of unauthorized access to sensitive network segments. This is particularly beneficial for industries with stringent compliance requirements, such as finance and healthcare.

In summary, Enterasys Networks' 802.1Q technology plays a pivotal role in modern networking by facilitating VLAN creation, enabling efficient traffic management, ensuring interoperability, and bolstering network security. As organizations increasingly rely on connected devices and data-driven processes, technologies like 802.1Q are essential for building robust, scalable, and secure networking environments.
