Chapter 5: SNMP and RMON Management

RMON Alarm Group – allows a network administrator to define alarm thresholds for any MIB variable. An alarm can be associated with Low Threshold, High Threshold, or both. A trigger can trigger an alarm when the value of a specific MIB variable exceeds or falls below a threshold.

RMON Event Group – allows a network administrator to define actions based on alarms. SNMP Traps are generated when RMON Alarms are triggered. The action taken in the Network Management Station depends on the specific network management application.

5.5 Bridge Groups Supported

The switch supports the following four groups of Bridge MIB (RFC 1493):

The dot1dBase Group – a mandatory group that contains the objects applicable to all types of bridges.

The dot1dStp Group – contains objects that denote the bridge’s state with respect to the Spanning Tree Protocol. If a node does not implement the Spanning Tree Protocol, this group will not be implemented. This group is applicable to any transparent only, source route, or SRT bridge that implements the Spanning Tree Protocol.

The dot1dTp Group – contains objects that describe the entity’s transparent bridging status. This group is applicable to transparent operation only and SRT bridges.

The dot1dStatic Group – contains objects that describe the entity’s destination-address filtering status. This group is applicable to any type of bridge that performs destination-address filtering.

LEH1104A-2SFP, LEH1008A-2SFP, LEH1008A-2MMSC, LEH906A-2GSFP, LEH906A-2MMST specifications

Black Box has established itself as a leader in providing robust networking solutions, and its range of hardened managed Ethernet switches, including the LEH1104A-4MMST, LEH1008A-2MMST, LEH906A-2SFP, and LEH906A-2MMSC, exemplifies this commitment. These switches are specifically designed to withstand the harsh environments often found in industrial and outdoor settings, making them ideal for applications such as transportation, utility management, and manufacturing.

The LEH1104A-4MMST model features four 10/100/1000 Mbps Ethernet ports, providing a flexible solution for networks requiring fast and reliable connectivity. It supports Power over Ethernet (PoE), enabling both data and power to be transmitted via a single cable, thereby simplifying installations and reducing wiring costs. This model also includes advanced features such as VLAN support, IGMP Snooping, and Quality of Service (QoS), ensuring optimized traffic management and network efficiency.

Similarly, the LEH1008A-2MMST switch offers eight ports and is built to handle a higher volume of connections without sacrificing performance. It boasts Layer 2 and Layer 3 management capabilities, allowing for complex network configurations and enhanced security measures such as port security and access control lists. The robust design and metal enclosure protect it from dust, moisture, and extreme temperatures.

The LEH906A-2SFP and LEH906A-2MMSC switches focus on modularity and connectivity flexibility, with SFP (Small Form-factor Pluggable) ports that enable users to choose the appropriate transceivers for their specific distances and media types, whether they require fiber or copper connections. Both models support dual-power inputs for redundancy and reliability, critical features for mission-critical applications.

All these switches are crafted to comply with industrial standards, ensuring reliable performance in diverse applications. Features such as redundant power supplies, fast recovery times, and support for protocols like SNMP (Simple Network Management Protocol) make network monitoring and management efficient and hassle-free.

In summary, Black Box’s hardened managed Ethernet switches, including the LEH1104A-4MMST, LEH1008A-2MMST, LEH906A-2SFP, and LEH906A-2MMSC, provide a perfect blend of durability, scalability, and management capabilities. These switches are engineered to meet the rigorous demands of industrial networking while ensuring seamless connectivity for diverse applications, making them an excellent investment for organizations looking to enhance their network infrastructure.
