GVRP

■If the switch already has a static VLAN assignment with the same VID as in the advertisement, and the port is configured to Auto for that VLAN, then the port will dynamically join the VLAN and begin moving that VLAN’s traffic. (For more detail on Auto, see “Per-Port Options for Dynamic VLAN Advertising and Joining” on page 9-79.)

■Ignore the advertisement for that VID and drop all GVRP traffic with that VID.

■Don’t participate in that VLAN.

Note also that a port belonging to a Tagged or Untagged static VLAN has these configurable options:

■Send VLAN advertisements, and also receive advertisements for VLANs on other ports and dynamically join those VLANs.

■Send VLAN advertisements, but ignore advertisements received from other ports.

■Avoid GVRP participation by not sending advertisements and dropping any advertisements received from other devices.

IP Addressing. A dynamic VLAN does not have an IP address, and moves traffic on the basis of port membership in VLANs. However, after GVRP creates a dynamic VLAN, you can convert it to a static VLAN. Note that it is then necessary to assign ports to the VLAN in the same way that you would for a static VLAN that you created manually. In the static state you can configure IP addressing on the VLAN and access it in the same way that you would any other static (manually created) VLAN.

Per-Port Options for Handling GVRP “Unknown VLANs”

An “unknown VLAN” is a VLAN that the switch learns of by GVRP. For example, suppose that in figure 9-58 (page 9-76),port 1 on switch “A” is connected to port 5 on switch “C”. Because switch “A” has VLAN 22 statically configured, while switch “C” does not have this VLAN statically configured, VLAN 22 is handled as an “Unknown VLAN” on port 5 in switch “C”. Con- versely, if VLAN 22 was statically configured on switch C, but port 5 was not a member, port 5 would become a member when advertisements for VLAN 22 were received from switch “A”.

When you enable GVRP on a switch, you have the per-port join-request options listed in table 9-8:

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.
