Overview of Using VLANs

VLAN Support and the Default VLAN

In the factory default configuration, VLAN support is enabled and all ports on the switch belong to the default VLAN (named DEFAULT_VLAN). This places all ports in the switch into one physical broadcast domain. In the factory- default state, the default VLAN is the primary VLAN.

You can partition the switch into multiple virtual broadcast domains by adding one or more additional VLANs and moving ports from the default VLAN to the new VLANs. (The switch supports up to 30 VLANs.) You can change the name of the default VLAN, but you cannot change the default VLAN’s VID (which is always “1”). Although you can remove all ports from the default VLAN, this VLAN is always present.

Which VLAN Is Primary?

Because certain features and management functions, such as single IP- address stacking, run on only one VLAN in the switch, and because DHCP and Bootp can run per-VLAN, there is a need to ensure that multiple instances of

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.
