Chapter 3: Configuration

3.7.2 VLAN Configuration

When MLD snooping is enabled on a VLAN, the switch acts to minimize unnecessary multicast traffic. If the switch receives multicast traffic destined for a given multicast address, it forwards that traffic only to ports on the VLAN that have MLD hosts for that address. It drops that traffic for ports on the VLAN that have no MLD hosts. The switch will use the last entry of the currently displayed entry as a basis for the next lookup. When the end is reached, the text “No more entries“ is shown in the displayed table. Use the Refresh button to start over.

Web Interface

To configure the MLD Snooping VLAN Configuration in the Web interface:

1.Click Configuration, MLD Snooping, VLAN Configuration.

2.Specify the VLAN ID with the number of entries per page.

3.Click “Refresh“ to refresh an entry.

4.Click “<< or >>“ to move to the previous or next entry.

Figure 3-35. The MLD Snooping VLAN Configuration screen.

Parameter Description

•VLAN ID: The VLAN ID of the entry.

•Snooping Enabled: Enable the per-VLAN MLD Snooping. Up to 32 VLANs can be selected.

•MLD Querier: A router sends MLD Query messages to a particular link. This Router is called the Querier. Enable the MLD Querier in the VLAN.

•Compatibility: Compatibility is maintained by hosts and routers taking appropriate actions depending on the versions of MLD

operating on hosts and routers within a network. Possible selections include: MLD-Auto, Forced MLDv1, and Forced MLDv2. The default compatibility value is MLD-Auto.

•RV: Robustness Variable. The Robustness Variable allows tuning for the expected packet loss on a network. The range is 1 to 255; the default robustness variable value is 2.

•QI: Query Interval. The Query Interval is the interval between General Queries sent by the Querier. The range is 1 to 31744 seconds; the default query interval is 125 seconds.

•QRI: Query Response Interval. The Maximum Response Delay used to calculate the Maximum Response Code inserted into the periodic General Queries. The range is 0 to 31744 in tenths of seconds; the default query response interval is 100 in tenths of seconds (10 seconds).

•LLQI (LMQI for IGMP): Last Listener Query Interval. The Last Listener Query Interval is the Maximum Response Delay used to calculate the Maximum Response Code inserted into Multicast Address Specific Queries sent in response to Version 1 Multicast Listener Done messages. It is also the Maximum Response Delay used to calculate the Maximum Response Code inserted into Multicast Address and Source Specific Query messages. The range is 0 to 31744 in tenths of seconds, the default last listener query interval is 10 in tenths of seconds (one second).

•URI: Unsolicited Report Interval. The Unsolicited Report Interval is the time between repetitions of a node’s initial report of interest in a multicast address. The range is 0 to 31744 seconds, default unsolicited report interval is 1 second.

LPB2848A, LPB2826A, LPB2810A, PoE+ Gigabit Managed Switch Eco specifications

The Black Box PoE+ Gigabit Managed Switch series, including the models LPB2810A, LPB2826A, and LPB2848A, presents a robust solution for businesses looking to enhance their network efficiency and reliability. Designed to support the growing demand for Power over Ethernet (PoE) devices, these switches provide the perfect backbone for modern network infrastructures.

One of the most significant features of this series is its PoE+ capability, which allows it to deliver power and data over a single Ethernet cable. This functionality simplifies cabling and installation, making it easier to deploy PoE devices such as IP cameras, VoIP phones, and wireless access points. The LPB2810A offers 8 PoE+ ports, the LPB2826A ups the ante with 24 ports, and the LPB2848A provides a whopping 48 ports, each capable of delivering up to 30 watts of power per port.

The managed switch system ensures that users can customize and optimize their network performance. With advanced features such as VLAN support, Quality of Service (QoS), and link aggregation, organizations can effectively manage traffic, prioritize critical applications, and potentially enhance overall network security. Furthermore, these switches support Layer 2 and Layer 3 functionalities, which allows for greater flexibility when implementing routing policies.

Another critical aspect of the LPB series is its built-in security features. The switches come equipped with advanced security protocols, including IEEE 802.1X port-based access control, which enables network administrators to authenticate devices before granting access to the network. This significantly reduces the risk of unauthorized access and ensures data integrity across the connected devices.

The Black Box PoE+ Gigabit Managed Switches are designed with reliability and ease of use in mind. Their fanless design promotes silent operation, making them ideal for deployment in both office environments and data centers. Additionally, the switches offer a user-friendly web-based interface and CLI options for straightforward management and configuration, catering to both novice and seasoned network administrators.

In conclusion, the Black Box PoE+ Gigabit Managed Switch series, featuring models LPB2810A, LPB2826A, and LPB2848A, stands out with its power-efficient design, extensive port options, and advanced security measures. These switches are an excellent choice for organizations that require a dependable and scalable networking solution to support their growing Ethernet and PoE device needs.
