STEP 1 Click VLAN Management > Voice and Media > SIP/H323 Based in the navigation window.

The table lists the administrative and operational statuses for SIP/H323 Auto VoIP on each interface, and shows the class that traffic will be assigned to. The traffic class corresponding to the highest priority queue on the port is chosen automatically.

STEP 2 Use the Interface Type menu to display ports or LAGs in the SIP/H323 Based Interface Settings Table.

STEP 3 Select the port or LAG interface to configure and click Edit.

STEP 4 Select Enable for the Auto VoIP Mode.

STEP 5 Click Apply and then click Close. Your changes are saved to the Running Configuration.

Media VLAN

The Media VLAN feature enables switch ports to carry voice, video, and signaling traffic with an assigned priority value. Assigning different priorities to traffic enables separation of media and data traffic coming into a port. The Media VLAN feature helps to ensure that the sound or video quality of an IP phone or video device is safeguarded from deterioration when data traffic on the port is high.

The inherent traffic isolation provided by VLANs ensures that inter-VLAN traffic is under management control and that network-attached clients cannot initiate a direct attack on voice components. The switch uses the IP-DSCP or 802.1p value in packets from media devices to assign this traffic to high priority queues.

The switch uses Media VLANs to support LLDP-MED applications. (See LLDP- MED for information on the protocol.) Each Media VLAN corresponds to an LLDP- MED application for a specific type of media traffic. The LLDP-MED applications are voice, voice signaling, guest voice, guest voice signaling, softphone voice, video conferencing, streaming video, and video signaling. Each Media VLAN is associated with the following parameters

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.
