The switches support various devices, including VoIP phones, surveillance cameras, printers<\/a>, and smart home devices. They offer reliable connectivity and high performance, making them a great choice for businesses looking to optimize their network infrastructure.<\/p>\n\n\n\n Proper placement and mounting of switches are crucial for the efficient operation of HPE Networking Instant On systems. Correctly positioning access points (APs) can significantly improve network coverage and performance. Following these guidelines ensures that your network infrastructure remains robust and capable of handling various demands;<\/p>\n\n\n\n Placing and mounting your switches correctly is essential for optimal performance. Here are some recommendations for placement and mounting of switches;<\/p>\n\n\n\n Effective cable management is essential for maintaining a well-organized and efficient data center. Properly managed cables ensure smooth operation, reduce maintenance efforts, and prevent potential issues. Below are the recommended techniques to manage cables in HPE Networking Instant On<\/a> deployments;<\/p>\n\n\n\n Power supply considerations and redundancy planning are crucial for maintaining a reliable network. Ensuring that switches have a consistent power source can prevent downtime and protect against power failures. Below are the key concepts of full and partial redundancy in power supply systems;<\/p>\n\n\n\n Full Redundancy<\/strong>: Full redundancy means each switch has two power supplies. If one fails, the other one takes over. This setup, known as 1:1 redundancy, ensures that the network keeps running without interruption.<\/p>\n\n\n\n Partial Redundancy<\/strong>: Partial redundancy involves one extra power supply for several switches. This system, called 1 redundancy, switches to the backup power supply if there’s a failure. However, it may take a little time for the backup to kick in. <\/p>\n\n\n\n Ensuring a reliable network requires careful attention to environmental factors like temperature, humidity, and ventilation. These factors can significantly impact the performance and longevity of your equipment. Let’s delve into the best practices for managing these environmental factors;<\/p>\n\n\n\n Temperature<\/strong>: Temperature extremes can affect network devices. Operating in high heat or frigid cold without proper equipment can lead to system failures. Keep your system in an environment no colder than 50\u00b0F (10\u00b0C) and no hotter than 95\u00b0F (35\u00b0C). Avoid placing your devices in direct sunlight or near heat sources to maintain optimal performance.<\/p>\n\n\n\n Humidity:<\/strong> Humidity control is crucial for preventing moisture-related issues. Excess moisture can damage electronic components and lead to corrosion. Ensure the environment maintains a stable humidity level to protect your equipment.<\/p>\n\n\n\n Ventilation<\/strong>: Good ventilation prevents overheating. Place your equipment in an enclosed, secure area with adequate airflow. Avoid blocking slots and openings, especially around fans, to ensure proper cooling. Regularly clean the installation site to prevent dust buildup that can block vents and cause overheating.<\/p>\n\n\n\n A network switch is responsible for forwarding data packets based on MAC addresses and works at the information link layer (Layer 2) of the OSI model. In contrast to hubs, which broadcast information to all devices that are connected, switches make intelligent judgements about where to distribute data, improving network efficiency.<\/p>\n\n\n\n Initial setup and configuration steps<\/strong><\/p>\n\n\n\n Setting up a network switch properly ensures efficient data flow and security. Switches, unlike hubs, make smart decisions on where to send data, boosting network performance. Here is how to configure your network switch from the start.<\/p>\n\n\n\n Step 1: Inspect Your Hardware<\/strong><\/p>\n\n\n\n Before you begin, check the model number and inspect your switch and cables for damage. Power on the switch and ensure all lights are working. Use a rollover cable to connect to the switch from your computer using a SSH client or terminal emulator.<\/p>\n\n\n\n Step 2: Set Up Management IP<\/strong><\/p>\n\n\n\n Assign a professional hostname and an IP address on the management VLAN. Follow your company\u2019s naming conventions.<\/p>\n\n\n\n Step 3: Check VTP Revision Number<\/strong><\/p>\n\n\n\n Use the command show VTP status to check your Virtual Trunking Protocol (VTP) revision numbers. Reset the revision number to zero by changing the config mode to transparent.<\/p>\n\n\n\n Step 4: Configure Access Ports<\/strong><\/p>\n\n\n\n Use your template for access port configuration. If you don\u2019t have one, use commands to set the port mode and VLAN.<\/p>\n\n\n\n Step 5: Configure Trunk Ports<\/strong><\/p>\n\n\n\n Check trunking protocol support with sh int g0\/1 capabilities. If ISL is supported, use switchport trunk encapsulation dot1q. If not, use switchport mode trunk.<\/p>\n\n\n\n Step 6: Generate RSA Keys<\/strong><\/p>\n\n\n\n Generate RSA keys for SSH access with the crypto key generate rsa command. Choose a key size between 360 and 2048.<\/p>\n\n\n\n Step 7: Set Up VTY Line Configuration<\/strong><\/p>\n\n\n\n Set the console line, enable password, and privilege exec password. Verify SSH access by typing sh ip ssh to confirm it is enabled. Log in from a remote machine to check SSH functionality.<\/p>\n\n\n\n A VLAN is a logical grouping of devices connected to the same network, regardless of their physical location. VLANs create a logical broadcast domain that can span multiple physical LAN segments. VLANs divide network traffic, improving security and performance. They allow specific groups of users to have access and security policies tailored to their needs. Here is how to set up VLANs;<\/p>\n\n\n\n Quality of Service (QoS) settings play a crucial role in managing network traffic effectively. They ensure that important applications like voice and video calls get the bandwidth and low latency they need, even during heavy network use.<\/p>\n\n\n\n Define Traffic Types<\/strong>: Identify different types of network traffic, such as voice, video, and data. Classify them based on how important they are and what performance they need.<\/p>\n\n\n\n Assign Priorities<\/strong>: Assign priority levels to each class of traffic. Critical applications like VoIP should have higher priority compared to less urgent data.<\/p>\n\n\n\n Allocate Bandwidth<\/strong>: Determine how much bandwidth each traffic class gets. Give more bandwidth to critical applications to ensure they function smoothly.<\/p>\n\n\n\n Choose Queue Types<\/strong>: Choose queuing methods like priority queuing or weighted fair queuing to match your priorities.<\/p>\n\n\n\n Set Traffic Shaping Parameters<\/strong>: Define how to control the rate of traffic transmission to prevent data bursts that can cause congestion.<\/p>\n\n\n\n Configure Routers and Switches<\/strong>: Access the configuration interface of your routers and switches. Set up class maps, policy maps, and service policies based on your QoS plan.<\/p>\n\n\n\n Apply DSCP Markings<\/strong>: Use Differentiated Services Code Point (DSCP) markings to show the priority of each packet. Configure devices to recognize and act on these markings.<\/p>\n\n\n\n Set Up Queuing Mechanisms<\/strong>: Set up queuing mechanisms on routers and switches. Adjust buffer sizes and weights to fit your prioritization strategy.<\/p>\n\n\n\n Implement Traffic Policing<\/strong>: Monitor and control the rate of incoming and outgoing traffic. Define what happens to non-compliant traffic, whether it’s dropped or marked down.<\/p>\n\n\n\n Configure Traffic Shaping<\/strong>: Configure traffic shaping to smooth out traffic flow, preventing sudden data bursts and congestion.<\/p>\n\n\n\n Deploy Monitoring Tools<\/strong>: Deploy tools to continuously monitor network performance. These tools give real-time visibility into metrics like latency, jitter, and packet loss.<\/p>\n\n\n\n Evaluate Policy Effectiveness<\/strong>: Regularly check if QoS policies are working as intended. Identify and fix any issues.<\/p>\n\n\n\n Use Adaptive QoS Features<\/strong>: Leverage adaptive QoS features in modern routers and switches. These automatically adjust QoS parameters based on network conditions.<\/p>\n\n\n\n<\/span>HPE Networking Instant On Deployment Best Practices<\/span><\/h2>\n\n\n\n
