SM-D-ES3G-48-P Cisco Enhanced Ether Service Module 48-Ports Refurbished

The SM-D-ES3G-48-P Cisco 48-Ports Managed Switch is a high-performance network switch that is designed to provide reliable and efficient network connectivity for enterprise and service provider networks. Some of the key technical specs and performance features of the SM-D-ES3G-48-P include:

• 48 Gigabit Ethernet ports: The SM-D-ES3G-48-P has 48 Gigabit Ethernet ports that provide high-speed connectivity for devices and services on the network. These ports support 10/100/1000Mbps data rates and provide full-duplex, non-blocking performance.
• Backplane capacity: The SM-D-ES3G-48-P has a backplane capacity of up to 216 Gbps, providing ample bandwidth for high-performance network applications and services.
• Power over Ethernet (PoE) support: The SM-D-ES3G-48-P supports Power over Ethernet (PoE) on all of its 48 ports, allowing network administrators to power devices such as IP phones and wireless access points without the need for additional power cables.
• Quality of Service (QoS): The SM-D-ES3G-48-P supports Quality of Service (QoS) and traffic prioritization, allowing network administrators to prioritize different types of network traffic to ensure that important applications and services receive the bandwidth they need to function properly.
• Virtual LANs (VLANs): The SM-D-ES3G-48-P supports Virtual LANs (VLANs), allowing network administrators to segment the network into multiple virtual networks, each with its own routing table. This feature can be used to isolate different parts of the network, prevent unauthorized access and to provide different routing options.
• Link Aggregation and Port Trunking: The SM-D-ES3G-48-P supports Link Aggregation and Port Trunking, allowing network administrators to bundle multiple switch ports together to form a single logical link. This can increase the bandwidth available to a specific device or service, improving network performance.
• Energy Efficient Ethernet (EEE): The SM-D-ES3G-48-P supports Energy Efficient Ethernet (EEE) which helps to reduce power consumption when the network is idle or underutilized.

These technical specs and performance features of SM-D-ES3G-48-P Cisco 48-Ports Managed Switch provide a powerful and flexible solution for enterprise and service provider networks that require high-density Gigabit Ethernet connectivity and advanced network management capabilities.

The SM-D-ES3G-48-P Cisco 48-Ports Managed Switch is equipped with advanced security features that help protect networks from unauthorized access and malicious attacks. Some of the key security features of the SM-D-ES3G-48-P include:

• Access Control Lists (ACLs): ACLs allow network administrators to set up rules that control which devices and users are allowed to access the network and which are not. This feature can be used to block unauthorized devices and users from accessing the network and to limit access to specific resources.
• Virtual LANs (VLANs): VLANs allow network administrators to segment a single physical network into multiple virtual networks. This feature can be used to create secure zones within the network that are isolated from each other, preventing unauthorized users from accessing sensitive resources.
• Port Security: Port security allows network administrators to set up rules that control which devices are allowed to connect to specific switch ports. This feature can be used to block unauthorized devices from connecting to the network and to limit the number of devices that can connect to a specific port.
• 802.1X Authentication: 802.1X authentication is a standard for controlling access to a network based on user credentials. This feature can be used to authenticate users before allowing them to access the network and to enforce role-based access control.
• DHCP Snooping: DHCP snooping is a feature that helps to prevent rogue DHCP servers from assigning IP addresses to unauthorized devices. This feature can be used to block unauthorized devices from getting an IP address and accessing the network.
• Dynamic ARP Inspection (DAI): DAI is a feature that helps to prevent ARP spoofing attacks by monitoring ARP traffic on the network and blocking any suspicious ARP packets.

These advanced security features help to protect the SM-D-ES3G-48-P Cisco 48-Ports Managed Switch against unauthorized access and malicious attacks, ensuring that your network remains secure and protected at all times.

The SM-D-ES3G-48-P Cisco 48-Ports Managed Switch is designed with advanced security and Quality of Service (QoS) features to ensure that your network remains secure and that important applications and services receive the bandwidth they need to function properly.

Quality of Service (QoS) features:

• Quality of Service (QoS): Network administrators can prioritize different types of network traffic to ensure that important applications and services receive the bandwidth they need to function properly.
• Traffic Prioritization: Network administrators can set up rules that specify which types of traffic should be given priority over others. This helps to ensure that important traffic such as voice and video are given priority over less important traffic.
• Link Aggregation and Port Trunking: Network administrators can bundle multiple switch ports together to form a single logical link. This can increase the bandwidth available to a specific device or service, improving network performance.

These security and QoS features of SM-D-ES3G-48-P Cisco 48-Ports Managed Switch provide a powerful and flexible solution for enterprise and service provider networks that require high-density Gigabit Ethernet connectivity and advanced network management capabilities to ensure a secure and efficient network.
