The type of the original default VLAN is changed from Default to Static, and it can be deleted. One exception is VLAN 1. Even if it is no longer designated as the default VLAN, VLAN 1 cannot be deleted.

To select a default VLAN:

STEP 1 Click VLAN Management > Default VLAN Settings in the navigation window.

STEP 2 Select the VLAN from the list.

STEP 3 Click Apply.

Voice and Media

Voice-over-Internet-Protocol (VoIP) allows using a computer data network for voice telephone calls. With the increased deployment of delay-sensitive applications such as VoIP in modern networks, proper QoS configuration is needed to ensure high-quality performance. The Voice and Media feature provides a simple classification mechanism for voice packets so that they can be prioritized above data packets.

The Voice and Media feature identifies VoIP streams in Ethernet switches and provides them with a better Class-of-Service (CoS) than ordinary traffic. The switch supports two types of Voice and Media:

Protocol-based—Identifies a VoIP session using the Session Initiation Protocol (SIP) and H.323 control traffic, and assigns these packets the highest priority on the voice VLAN.

OUI-based—Ports that are enabled for this feature automatically become members of the configured voice VLAN. The switch detects Organizationally Unique Identifier (OUI) values in the first three bytes of the MAC addresses in client packets to classify them on the VoIP VLAN and prioritize them on the Auto VoIP-enabled ports.

SLM2008PTNA specifications

Cisco Systems SLM2008PTNA is a robust network switch designed specifically for small to medium-sized businesses. It operates with 8 Fast Ethernet ports, providing advanced features and best-in-class performance to enhance your network infrastructure. This model ensures seamless connectivity for multiple devices, making it an ideal choice for environments requiring reliable network communication.

One of the standout features of the SLM2008PTNA is its Layer 2 switching capabilities. This switch supports auto-negotiation, which allows each port to automatically detect the speed of the connected device and adjust accordingly. This ensures optimal performance and smooth operation across various connected devices. Additionally, the switch supports a non-blocking architecture, ensuring that bandwidth is not shared, which significantly enhances data transmission speed.

Power over Ethernet (PoE) is another key technology incorporated into the Cisco SLM2008PTNA. It simplifies the installation of network devices such as VoIP phones, security cameras, and wireless access points by supplying power through the Ethernet cable. This eliminates the need for separate power sources, reducing installation costs and increasing flexibility in device placement.

Moreover, the SLM2008PTNA comes equipped with advanced security features, such as port security and VLAN support. Port security allows network administrators to restrict access to the network based on MAC addresses, preventing unauthorized access and enhancing network security. The support for Virtual Local Area Networks (VLANs) enables the segmentation of the network into different logical networks, improving traffic management and security within each segment.

The switch is designed for easy management and monitoring, featuring a user-friendly web interface that simplifies configuration. This allows network administrators to quickly set up and manage the device without requiring extensive technical knowledge. Additionally, its compact design makes it suitable for desktop or rack-mount installation, maximizing space efficiency in network environments.

In conclusion, the Cisco Systems SLM2008PTNA is an essential component for small to medium-sized businesses looking to enhance their network performance. With its Layer 2 switching capabilities, Power over Ethernet support, advanced security features, and ease of management, this switch provides a well-rounded solution for modern networking needs, delivering reliable performance and scalability for growth.
