•Event: a function that operates with the Alarm group to define an action that will be taken when an alarm condition occurs. The event may write a log entry and/or send a trap message.

Note that RMON statistics and other information can only be viewed using a connection to the on-board Web agent or via other compatible SNMP management applications.

Port Mirroring

The VH-8TX1UM/VH-8TX1MF switch includes the ability to mirror the traffic being switched on any port for purposes of network traffic analysis and connection integrity. When this feature is enabled, a protocol analyzer or RMON probe can be connected to the mirror port. You can only mirror one port to another port at one time. Port mirroring occurs at the same speed configured for the port (10 Mbps-to-10 Mbps or 100 Mbps-to-100 Mbps). Port mirroring is configurable using the console interface menus, the

on-board Web agent, or via SNMP.

Auto-negotiation

Auto-negotiation is a process that permits the switch to automatically select the operational modes of its 10/100 RJ-45 ports. Upon first being connected, the switch detects the speed of the network the port is connected to, either 10 Mbps or 100 Mbps, and the type of communication setting, half or full duplex. The port is then automatically set by the switch to operate in the proper mode, without user intervention. It is not required that the network device being connected to the switch supports auto-negotiation as the VH-8TX1UM/VH-8TX1MF switch automatically adjusts to the network device’s communication settings. Auto-negotiation is configurable using the console interface menus, the on-board Web agent, or via SNMP.

Multicast Filtering

The purpose of IP multicast filtering is to optimize a switched network’s performance, so multicast packets will only be forwarded to those ports containing multicast group hosts or multicast routers/switches, instead of flooding traffic to all ports. The VH-8TX1UM/VH-8TX1MF supports IP multicast filtering not only by passively monitoring IGMP Query and Report messages, but also by actively sending Query messages to learn the location of multicast routers/switches and member hosts in multicast groups. IGMP is configurable using the console interface menus, the on- board Web agent, or via SNMP.

Port Security

Port security protects your network from unauthorized users by preventing their connected devices gaining access to the network. The port security feature allows each port to learn, or be configured with, a list of MAC addresses of devices that are authorized to access the network through that port. Packets received on the port that have a source MAC

VH-8TX1MF, VH-8TX1UM specifications

Enterasys Networks, a well-respected name in the field of networking technology, has introduced the VH-8TX1UM and VH-8TX1MF models, which cater to the ever-evolving needs of modern enterprises. These devices are designed to enhance connectivity, improve network performance, and provide enhanced security for users across various environments.

The VH-8TX1UM model is a versatile Layer 2/3 managed switch that features eight 10/100/1000BASE-T Ethernet ports. This configuration allows for seamless connectivity with existing network infrastructure while providing the necessary throughput for bandwidth-hungry applications. It supports a range of features including VLAN tagging, port mirroring, and link aggregation, making it ideal for both small and medium-sized businesses looking to scale their networks without significant hardware investments.

Meanwhile, the VH-8TX1MF model is designed with a focus on modularity. It not only features eight Ethernet ports but also includes slots for additional modules, allowing organizations to customize their network setup based on specific requirements. The modular design ensures flexibility, enabling future upgrades without the need for complete hardware replacements. This characteristic is particularly beneficial for companies that anticipate growth or changes in their network architecture.

Both models boast advanced technologies such as Quality of Service (QoS) and Power over Ethernet (PoE). QoS prioritizes critical network traffic, ensuring that voice and video applications receive the bandwidth they need for optimal performance. PoE allows for the powering of devices like IP cameras, phones, and wireless access points directly through the Ethernet cables, simplifying installations and reducing the need for additional power sources.

In terms of security, Enterasys equips the VH-8TX1UM and VH-8TX1MF with robust features to safeguard sensitive data. These include access control lists and port security settings, which protect against unauthorized access and mitigate potential threats. Additionally, the switches support network management protocols such as Simple Network Management Protocol (SNMP), enabling efficient monitoring and management of network performance.

Overall, the Enterasys VH-8TX1UM and VH-8TX1MF models stand out with their combination of performance, flexibility, and security. They present a compelling option for enterprises aiming to enhance their networking capabilities while ensuring that they are well-equipped to handle future technological advancements.
