MULTICAST FILTERING

multicasting, one of these devices is elected “querier” and assumes the role of querying the LAN for group members. It then propagates the service requests on to any upstream multicast switch/router to ensure that it will continue to receive the multicast service.

Note: Multicast routers use this information, along with a multicast routing protocol such as DVMRP or PIM, to support IP multicasting across the Internet.

Command Attributes

•IGMP Status — When enabled, the switch will monitor network traffic to determine which hosts want to receive multicast traffic. This is also referred to as IGMP Snooping. (Default: Enabled)

•Act as IGMP Querier — When enabled, the switch can serve as the Querier, which is responsible for asking hosts if they want to receive multicast traffic. (Default: Enabled)

•IGMP Query Count — Sets the maximum number of queries issued for which there has been no response before the switch takes action to drop a client from the multicast group. (Range: 2-10; Default: 2)

•IGMP Query Interval — Sets the frequency at which the switch sends IGMP host-query messages. (Range: 60-125 seconds; Default: 125)

•IGMP Report Delay — Sets the time between receiving an IGMP Report for an IP multicast address on a port before the switch sends an IGMP Query out of that port and removes the entry from its list. (Range: 5-25 seconds; Default: 10)

•IGMP Query Timeout — The time the switch waits after the previous querier stops before it considers the router port (i.e., the interface which had been receiving query packets) to have expired. (Range: 300-500 seconds; Default: 300)

•IGMP Version — Sets the protocol version for compatibility with other devices on the network. (Range: 1-2; Default: 2)

TigerSwitch specifications

The SMC Networks TigerSwitch series represents a robust line of Ethernet switches designed to cater to a wide range of networking needs, from small businesses to enterprise environments. With a strong emphasis on performance, reliability, and ease of use, the TigerSwitch series has garnered a reputation for delivering effective solutions for today’s demanding data communication requirements.

One of the standout features of the TigerSwitch is its support for Gigabit Ethernet, which enables higher data transfer rates and reduced latency. This performance boost is crucial for businesses that rely on bandwidth-heavy applications such as VoIP, video conferencing, and large file transfers. Many models in the series come with multiple Gigabit Ethernet ports, providing businesses with the flexibility to connect various devices and expand their networks seamlessly.

The TigerSwitch series also incorporates advanced Layer 2 switching capabilities, including features such as VLAN support and QoS (Quality of Service). VLAN support allows network administrators to segment network traffic, enhancing security and improving overall network performance. By segregating traffic based on user groups or applications, VLANs help manage bandwidth more effectively. QoS is particularly important in environments where voice and video services compete for bandwidth, as it prioritizes critical applications ensuring minimal interruptions in service quality.

Another key characteristic of the TigerSwitch is its user-friendly management interface. Many models come with web-based management capabilities, making it simpler for network administrators to configure settings, monitor performance, and troubleshoot issues. Additionally, the series supports SNMP (Simple Network Management Protocol), allowing for centralized network management and monitoring, which is essential for larger networks.

The TigerSwitch series also promotes energy efficiency, aligning with modern eco-friendly practices. Many of the switches feature Power over Ethernet (PoE) support, allowing them to deliver power to connected devices such as IP cameras and wireless access points over the same Ethernet cable used for data. This not only simplifies cabling requirements but also contributes to reducing overall power consumption, which is a consideration for both cost savings and environmental impact.

In conclusion, the SMC Networks TigerSwitch series stands out due to its combination of performance, advanced features, and ease of management. With its Gigabit Ethernet capabilities, VLAN and QoS support, user-friendly interfaces, and energy-efficient design, the TigerSwitch is well-equipped to meet the diverse needs of modern networking environments, offering reliable solutions that cater to both current demands and future expansions.
