Port-Based Virtual LANs (Static VLANs)

saved by not allowing packets to flood out all ports. An external router is required to enable separate VLANs on a switch to communicate with each other.

For example, referring to figure 9-39,if ports 1 through 4 belong to VLAN_1 and ports 5 through 8 belong to VLAN_2, traffic from end-node stations on ports 2 through 4 is restricted to only VLAN_1, while traffic from ports 5 through 7 is restricted to only VLAN_2. For nodes on VLAN_1 to communicate with VLAN_2, their traffic must go through an external router via ports 1 and 8.

Figure 9-39. Example of Routing Between VLANs via an External Router

Overlapping (Tagged) VLANs. A port on the SMC6624M switch can be a member of more than one VLAN if the device to which it is connected complies with the 802.1Q VLAN standard. For example, a port connected to a central server using a network interface card (NIC) that complies with the 802.1Q standard can be a member of multiple VLANs, allowing members of multiple VLANs to use the server. Although these VLANs cannot communicate with each other through the server, they can all access the server over the same connection from the switch. Where VLANs overlap in this way, VLAN “tags” are used to distinguish between traffic from different VLANs.

SMC6624M specifications

SMC Networks SMC6624M is a robust and versatile managed switch designed to meet the needs of enterprises seeking reliable network solutions. This device features 24 Gigabit Ethernet ports that allow for high-speed data transfer, making it ideal for environments that demand high bandwidth. The SMC6624M is particularly suited for small to medium-sized businesses that require a powerful network backbone to support various applications, including voice, video, and data transmission.

One of the standout features of the SMC6624M is its Layer 2 and Layer 3 switching capabilities, enhancing the flexibility and efficiency of network management. The switch supports VLANs (Virtual Local Area Networks), which allow administrators to segment network traffic for improved security and performance. This capability is essential for organizations looking to optimize their network resources and apply policies that enhance security.

The SMC6624M also integrates advanced Quality of Service (QoS) features, enabling the prioritization of network traffic. This is particularly useful for applications such as VoIP and video conferencing, where maintaining low latency and jitter is crucial for ensuring a seamless user experience. Users can define traffic classes and manage bandwidth allocation, which helps in maintaining the quality of critical applications even during peak usage times.

In terms of connectivity and performance, the SMC6624M includes 4 Gigabit SFP ports, allowing for fiber optic connections to extend network reach and provide flexibility in deployment. The ability to take advantage of high-speed fiber connections means businesses can scale their networks as needed without significant infrastructure changes.

Management options for the SMC6624M are comprehensive. It supports SNMP (Simple Network Management Protocol) for monitoring and managing network performance effectively. Additionally, the switch can be configured using a web-based interface, command-line interface (CLI), or through SNMP, providing flexibility to network administrators with different preferences and expertise.

Furthermore, the SMC6624M is built with a fanless design, which ensures quiet operation and is energy efficient. Its compact form factor and sturdy build make it suitable for installation in various environments, including data centers and office settings.

Overall, the SMC Networks SMC6624M stands out for its combination of speed, flexibility, and management features, making it an excellent choice for businesses looking to enhance their network infrastructure. With a focus on reliability and performance, this managed switch promises to deliver the capabilities that today's modern networks demand.
