C2811-3G-S-SEC/K9 Cisco Integrated Service Router 2 Ports Refurbished

The C2811-3G-S-SEC/K9 Cisco 2 Ports Integrated Service Router includes several advanced security features, such as:

• Stateful firewall: This feature monitors and controls incoming and outgoing network traffic based on a set of predefined security rules.
• Virtual private network (VPN) support: The router supports multiple VPN protocols, including IPsec and SSL, to establish secure connections between remote networks or devices.
• Intrusion prevention system (IPS): This feature monitors network traffic for signs of malicious activity and takes action to block it.
• Advanced Encryption Standard (AES) and Data Encryption Standard (DES) encryption: These algorithms can be used to encrypt sensitive data transmitted over the network.
• Secure Shell (SSH) and Secure Copy (SCP) support: These protocols provide secure access to the router's command-line interface and allow for secure file transfers.
• Advanced Application Visibility and Control (AVC): This feature provides deep visibility and control of all types of application traffic, such as HTTP, VoIP, video, and peer-to-peer.
• Support for advanced security features such as Cisco TrustSec, Identity Services Engine (ISE) etc.
• Cisco IOS Software Security: This feature provides security for the Cisco IOS Software that runs on the router, including protection against unauthorized access, malware, and attacks.

The C2811-3G-S-SEC/K9 Cisco 2 Ports Integrated Service Router is a powerful device that can handle a wide range of network traffic and security needs. To maximize its performance and scalability, it is important to optimize the router's configurations, prioritize traffic using Quality of Service (QoS), and take advantage of the router's hardware and software features.

• Optimize network configurations: This includes ensuring that the router is configured with the appropriate speed and duplex settings for the connected devices, and that the correct routing protocols are in use. Properly configuring the router's interfaces and routing protocols can help to improve the overall performance and scalability of the network.
• Use Quality of Service (QoS) to prioritize traffic: QoS is a feature that allows you to prioritize certain types of network traffic over others. By prioritizing important traffic, such as voice or video, over less critical traffic, you can ensure that the router's resources are being used effectively. This can help to improve the overall performance of the network.
• Utilize the router's hardware-based encryption acceleration: The C2811-3G-S-SEC/K9 Cisco 2 Ports Integrated Service Router has built-in encryption and decryption acceleration capabilities. By offloading encryption and decryption processes to the router's hardware, you can reduce the load on the CPU and improve performance.
• Use the Cisco Performance Routing (PfR) feature: PfR is a feature that can help to improve performance by dynamically selecting the best path for traffic based on real-time network conditions. By using PfR, you can ensure that traffic is being routed over the most efficient path, which can help to improve the overall performance and scalability of the network.
• Upgrade the router's memory and flash: As the traffic increases, upgrading memory and flash can help to improve the performance and scalability of the router. This can help to ensure that the router has enough resources to handle the increased traffic.
• Use the Cisco IOS Software Feature Sets: Upgrading the Cisco IOS Software Feature Set on the router can unlock additional features that can help improve performance and scalability. By using the appropriate feature set, you can take advantage of features such as advanced security, QoS, and VPN support.
• Utilize the Advanced Application Visibility and Control (AVC) feature: AVC provides deep visibility and control of all types of application traffic, such as HTTP, VoIP, video, and peer-to-peer. By using this feature, you can optimize the performance and scalability of your network by controlling the application traffic.
• Utilize the Multiple SSID feature: The Multiple SSID feature allows you to create multiple wireless networks on the same router. This can help to improve the scalability and performance of wireless networks.
• Utilize the VPN feature: Using VPN feature can help to improve scalability and performance by securely connecting remote networks and devices. By using VPN, you can securely connect remote networks and devices to your main network, which can help to improve the overall performance and scalability of your network.

The C2811-3G-S-SEC/K9 Cisco 2 Ports Integrated Service Router has a variety of Quality of Service (QoS) capabilities that allow you to prioritize certain types of network traffic over others. This can help to ensure that important traffic, such as voice or video, is given priority over less critical traffic, improving the overall performance of the network.

• Class-Based Weighted Fair Queuing (CBWFQ): CBWFQ is a feature that allows you to assign different levels of priority to different types of traffic. This can help to ensure that important traffic is given priority over less critical traffic.
• Low Latency Queuing (LLQ): LLQ is a feature that allows you to give priority to delay-sensitive traffic, such as voice and video. This can help to ensure that these types of traffic are delivered with minimal delay, improving the overall quality of service.
• Traffic Shaping: Traffic shaping is a feature that allows you to control the rate at which traffic is sent. This can help to prevent network congestion and ensure that important traffic is delivered in a timely manner..
• Compression and Encryption: The C2811-3G-S-SEC/K9 Cisco 2 Ports Integrated Service Router also has built-in compression and encryption capabilities that can help to improve the performance of your network by reducing the amount of bandwidth required to transmit data.
• Quality of Service (QoS) on VPN Tunnel: The router also supports Quality of Service (QoS) on VPN Tunnel which allows you to prioritize the traffic across VPN Tunnel and ensure that important traffic is given priority over less critical traffic.
