Advanced Network Management Capabilities

The J4904A HPE ProCurve 48 Ports 10/100/1000BT 4 Dual SFP GigaBit Ethernet Switch is a high-performance network switch designed for use in large and complex networks. It offers advanced network management capabilities that make it ideal for use in enterprise environments. Some of the key features include:

  • L3 routing capabilities: The switch supports Layer 3 routing protocols such as OSPF, BGP, and RIP, allowing for more efficient and flexible network management.
  • Quality of Service (QoS): The switch allows for advanced traffic management, with the ability to prioritize different types of traffic and ensure that critical applications receive the bandwidth they need.
  • VLAN and VLAN tagging: The switch supports VLANs and VLAN tagging, allowing for the creation of isolated networks within the same physical infrastructure.
  • Security features: The switch includes advanced security features such as IEEE 802.1X port-based authentication, access control lists (ACLs), and DHCP snooping.
  • Management and monitoring: The switch offers a variety of management and monitoring options, including a web-based interface, SNMP, and command-line interface (CLI).
  • High availability: The switch supports features such as Link Aggregation Control Protocol (LACP) and Spanning Tree Protocol (STP) to ensure that the network remains up and running even in the event of a failure.
Performance and Scalability

The J4904A HPE ProCurve 48 Ports 10/100/1000BT 4 Dual SFP GigaBit Ethernet Switch is a high-performance and scalable networking solution that is suitable for large enterprises and data centers.

In terms of performance, the switch supports a maximum data transfer rate of 52 Gbps, allowing for fast and efficient data transfer between connected devices. It also supports advanced features such as Quality of Service (QoS) and Link Aggregation Control Protocol (LACP) for optimizing network traffic and ensuring smooth communication between devices.

In terms of scalability, the switch has 48 ports that support 10/100/1000BT and 4 dual SFP ports for Gigabit Ethernet connectivity. This allows for a large number of devices to be connected to the switch, making it suitable for large networks with many devices. Additionally, the switch supports virtual LANs (VLANs) and Layer 3 routing, allowing for easy segmentation and management of different network segments.

Security Features

The J4904A HPE ProCurve 48 Ports 10/100/1000BT 4 Dual SFP GigaBit Ethernet Switch offers several security features to protect networks from unauthorized access and malicious activity. These features include:

  • Access Control Lists (ACLs): The switch allows administrators to create and apply ACLs to restrict access to certain network resources based on IP addresses, protocols, and ports.
  • Port Security: Administrators can configure the switch to limit the number of MAC addresses that can be learned on a specific port, preventing unauthorized devices from connecting to the network.
  • IEEE 802.1X Authentication: The switch supports IEEE 802.1X authentication, which allows administrators to authenticate network users based on their credentials, such as a username and password.
  • Virtual LAN (VLAN) Tagging: The switch supports VLAN tagging, which allows administrators to create virtual networks that are isolated from one another, providing an additional layer of security.
  • Quality of Service (QoS): The switch supports QoS, which allows administrators to prioritize network traffic based on its importance, ensuring that critical applications and services receive the necessary bandwidth.
  • Remote Management: The switch allows administrators to remotely manage and monitor the network using a web-based interface, providing an additional level of security by allowing remote access only to authorized users.
  • SSL Encryption: The switch supports SSL encryption, which encrypts data transmitted over the network, preventing unauthorized access and ensuring the confidentiality of sensitive information.
  • SNMPv3: The switch supports SNMPv3, which provides secure, authenticated, and encrypted communication between the switch and the management console, ensuring that only authorized users can access and manage the switch.
