Description
Security Features and Protocols
The 851-0317 Dell Networking 48 Port 10GBE SFP+ 2P QSFP+ 4P QSFP28 Switch is equipped with a range of security features and protocols to protect your network. Some of these features include:
- Access control: This switch allows you to define access control rules and permissions to control who has access to your network and what they can do.
- VLANs: Virtual LANs (VLANs) can be created to segment the network into smaller, logically isolated groups, increasing security and reducing the risk of unauthorized access.
- 802.1X authentication: The switch supports 802.1X authentication, which is a security protocol that authenticates network users and devices before they are allowed to access the network.
- SSH and SSL encryption: The switch supports SSH and SSL encryption, which encrypts network data in transit, preventing eavesdropping and tampering.
- RADIUS and TACACS+: The switch supports RADIUS and TACACS+ authentication protocols, which allow administrators to centralize authentication for all devices on the network.
- Dynamic ARP Inspection: Dynamic ARP Inspection (DAI) helps protect against ARP spoofing attacks by validating ARP packets before they are forwarded to the network.
- Spanning Tree Protocol (STP): The switch supports Spanning Tree Protocol (STP), which helps prevent loops in the network by disabling redundant links.
- Link Aggregation Control Protocol (LACP): The switch supports Link Aggregation Control Protocol (LACP), which allows multiple physical links to be combined into a single logical link, providing increased bandwidth and fault tolerance.
Quality of Service (QoS) and Traffic Control
The 851-0317 Dell Networking 48 Port 10GBE SFP+ 2P QSFP+ 4P QSFP28 Switch is equipped with Quality of Service (QoS) and Traffic Control features. These features help to manage and prioritize network traffic to ensure the efficient and effective delivery of critical data.
Quality of Service (QoS) allows administrators to classify network traffic based on specific criteria such as priority, application, or protocol. This enables the switch to provide different levels of service to different types of traffic, ensuring that critical data gets priority over non-critical data.
Traffic Control allows administrators to regulate the flow of network traffic based on specific rules and policies. This can help to prevent congestion, reduce the risk of dropped packets, and improve the overall performance of the network.
Physical Design and Robustness
The 851-0317 Dell Networking 48 Port 10GBE SFP+ 2P QSFP+ 4P QSFP28 Switch is designed for robustness and reliability. The switch is built with a 1U form factor, making it compact and suitable for dense data center environments. The switch is equipped with 48 ports, which include 2P SFP+ ports, 2P QSFP+ ports, and 4P QSFP28 ports. These ports allow for the connectivity of high-speed Ethernet and Fiber Channel storage networks.
The switch has a durable metal casing that protects against physical damage and enhances its stability in harsh environments. The metal casing is also used for passive cooling, which helps to regulate the temperature of the switch, ensuring its longevity and performance.
The switch also has a redundant power supply, which ensures that there is no interruption to the network even in the event of a power outage. This power supply design increases the reliability and availability of the switch, which is critical for mission-critical networks.
In conclusion, the 851-0317 Dell Networking 48 Port 10GBE SFP+ 2P QSFP+ 4P QSFP28 Switch is designed for robustness and reliability, making it ideal for data center environments that require high performance and low downtime. The switch’s compact size, metal casing, and redundant power supply make it a durable and dependable choice for organizations looking to build a high-speed, high-performance network.
