MIB-2 defines a set of manageable objects in various layers of the TCP/IP protocol suites. MIB-2 covers all manageable objects from layer 1 to layer 4 and, as a result, is the major SNMP MIB supported by all vendors in the net- working industry. The GigaSwitch supports a complete implementation of SNMP Agent and MIB-2.

RMON MIB (RFC 1757) and Bridge MIB (RFC 1493)

The GigaSwitch provides hardware-based RMON counters in the switch chipset. The switch manager CPU polls these counters periodically to collect the statistics in a format that complies with the RMON MIB definition.

RMON GROUPS SUPPORTED

The GigaSwitch supports the following RMON MIB groups defined in RFC1757:

RMON Statistics Group maintains utilization and error statistics for the switch port being monitored.

RMON History Group gathers and stores periodic statistical samples from the previous Statistics Group.

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 a threshold, falls below a thresh- old, or 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 trig- gered. The action taken in the Network Management Station depends on the specific network management application.

BRIDGE GROUPS SUPPORTED

The GigaSwitch supports the following four groups of Bridge MIB (RFC1493):

The dot1dBase Group a mandatory group that contains the objects appli- cable to all types of bridges.

The dot1dStp Group contains the 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 imple- ments 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 destina- tion-address filtering status. This group is applicable to any type of bridge which performs destination-address filtering.

EG24M specifications

The Linksys EG24M is a powerful and versatile network switch that caters to the needs of both small and medium-sized businesses. With its robust features and reliable performance, the EG24M has established itself as a go-to choice for enhancing network connectivity in diverse environments.

At the heart of the Linksys EG24M are 24 Ethernet ports, all of which support Gigabit speed. This allows for rapid data transfer rates, making it ideal for bandwidth-intensive applications such as video streaming, online gaming, and large file transfers. All ports are auto-sensing and configure themselves automatically to the speed of connected devices, optimizing performance without the need for manual configurations.

One of the standout features of the EG24M is its support for Power over Ethernet (PoE). This technology enables the switch to deliver electrical power along with data over standard Ethernet cables, eliminating the need for additional power supplies for PoE-enabled devices like IP cameras, VoIP phones, and wireless access points. This simplifies installation and reduces clutter, allowing for flexible deployments in various environments.

The Linksys EG24M also incorporates advanced Layer 2 switching capabilities. It supports features such as VLANs (Virtual Local Area Networks), allowing network segmentation to enhance security and traffic management. This is particularly beneficial in larger networks where different departments or functions require isolated communication channels. Additionally, the switch supports Quality of Service (QoS) features, enabling prioritization of critical network traffic to ensure smooth performance for essential applications.

Security is another key aspect of the Linksys EG24M. It has built-in features to protect the network against unauthorized access, ensuring that sensitive data remains secure. The switch also supports storm control and broadcast control to mitigate network congestion and enhance overall performance.

In terms of design, the EG24M features a compact and robust form factor, which makes it suitable for mounting in standard racks or desktop environments. Its fanless design ensures silent operation, making it ideal for office use where noise can be a distraction.

In conclusion, the Linksys EG24M is an efficient and reliable network switch that combines high-speed connectivity with advanced features like PoE, VLAN support, and enhanced security. Its design and capabilities make it a valuable asset for any business looking to improve its network infrastructure. With Linksys backing its technology, the EG24M is poised to deliver exceptional performance and reliability for diverse networking needs.
