Protocol Ports Configuration Screen

11.Press ENTER and the new settings are displayed under the VLAN ID, Protocol Type, and Configured Ports values.

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

13.Press ENTER. The message “SAVED OK” displays and the settings are saved. A particular line of data displayed may now be highlighted to display the Protocol Ports Configuration screen, as described in Section 3.8.3, to view, add, or delete ports from the priority in the highlighted line.

3.8.3Displaying the Protocol Types on Current Ports

To display the current ports and port types associated with a VLAN ID, the Protocol Ports Configuration screen must be displayed. While in that screen, ports and their port type may be added to, or current ones deleted from, the VLAN ID. To access the Protocol Ports Configuration screen, proceed as follows:

1.Highlight the line of information containing the VLAN ID of interest to display the current ports and port types associated with that VLAN ID. The entries in the line of information must have been saved before you can select it to display the Protocol Ports Configuration screen.

2.Press ENTER. The Protocol Ports Configuration screen displays, showing all current ports and port types associated with that VLAN ID. For more information about the Protocol Ports Configuration screen and how to use it, refer to Section 3.9.

When to Use

To display the current ports and port types associated with a VLAN and protocol selected in the Protocol VLAN Configuration screen described in Section 3.8.

NOTE: The line of information selected must have been saved before it can be used to access the Protocol Ports Configuration screen as described below.

How to Access

Use the arrow keys to highlight a line of information under the VLAN ID/Protocol Type/Configured Ports BitMap columns in the Protocol Priority Configuration screen and press ENTER. The Protocol Ports Configuration screen displays.

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.
