C1921-3G-U-K9 Cisco 1921 Multi Service Router 2 Ports New

The C1921-3G-U-K9 Cisco 1921 router is a multi-service router that offers a variety of advanced security features to help protect your network from external threats. Some of the key advanced security features of this router include:

• Firewall: The router has a built-in firewall that can be configured to protect the network from external threats. The firewall can be configured to block specific types of traffic, such as malicious packets or unwanted connections, based on rules and policies.
• VPN: The router supports Virtual Private Network (VPN) which allows to securely connect remote workers or branch offices to the main network. This can be done using various VPN protocols such as IPsec, L2TP, and PPTP.
• Intrusion Prevention System (IPS): The router has an Intrusion Prevention System (IPS) that can be configured to detect and prevent intrusions on the network. It can also be configured to generate alerts and take preventative measures when an intrusion is detected.
• Content Filtering: The router has a content filtering feature which can block access to specific types of content such as websites, web applications or unwanted traffic.
• Authentication: The router supports various authentication methods like local, RADIUS, TACACS+ and Kerberos which can be used to authenticate users before allowing them to access the network.
• Access Control: The router has an Access Control feature which can be configured to restrict access to specific devices, users or groups based on certain conditions like time, location, or device type.
• Encryption: The router supports various encryption protocols such as AES, 3DES, and DES which can be used to encrypt sensitive data as it travels over the network.
• These advanced security features make the C1921-3G-U-K9 Cisco 1921 router a powerful solution for organizations that need to secure their networks against external threats. It's important to note that these features may have different capabilities and options depending on the firmware version of the router.

Maximizing performance and scalability of the C1921-3G-U-K9 Cisco 1921 Multi Service 2 Ports Router means ensuring that the router can handle high traffic loads and adapt to changes in the network as it grows. This can be achieved through several steps:

• Utilizing Quality of Service (QoS) features: The router has built-in QoS features that allow you to prioritize different types of traffic, such as voice or video, to ensure that critical applications receive the bandwidth they need.
• Using link aggregation: Link aggregation allows you to bundle multiple physical links together, such as Ethernet cables, to increase bandwidth and provide redundancy. This means that if one link goes down, traffic can still be sent and received through the other links.
• Optimizing the routing table: Regularly reviewing and optimizing the routing table ensures that the most efficient routes are being used, reducing the load on the router and improving performance.
• Monitoring and troubleshooting: Regularly monitoring the router's performance and troubleshooting any issues that arise helps to keep the router running at peak performance.
• Upgrading memory and flash: If the router is frequently running low on memory, upgrading the memory and flash can improve performance.
• Using advanced routing protocols: Advanced routing protocols like OSPF or EIGRP can optimize the routing table and improve the overall scalability of the network.
• Utilizing VPN concentrator or firewall: A VPN concentrator or firewall can offload VPN and security processing from the router, improving its performance.
• Using dynamic routing protocols: Dynamic routing protocols allow the router to automatically adjust to changes in the network topology, improving scalability.

By implementing these steps, you can help ensure that the C1921-3G-U-K9 Cisco 1921 Multi Service 2 Ports Router is able to handle high traffic loads and continue to perform well as your network grows. It's important to note that these steps may have different capabilities and options depending on the firmware version of the router.

The C1921-3G-U-K9 Cisco 1921 Multi Service 2 Ports Router has built-in Quality of Service (QoS) capabilities that allow you to prioritize different types of network traffic. This can help ensure that critical applications, such as voice and video, receive the bandwidth they need while less important traffic is given lower priority. The QoS features of the router include:

• Class-Based Weighted Fair Queuing (CBWFQ): This feature allows you to assign different priorities to different types of traffic based on the traffic's IP precedence or DSCP value.
• Low Latency Queuing (LLQ): This feature allows you to prioritize delay-sensitive traffic, such as voice and video, by allocating a specific amount of bandwidth to that traffic.
• Weighted Random Early Detection (WRED): This feature helps prevent network congestion by randomly dropping packets when the network is busy. The router can be configured to give priority to certain types of traffic, such as voice, over other types of traffic, such as data.
• Traffic Shaping: This feature allows you to control the rate at which traffic is sent and received, helping to prevent network congestion.
• Policy-Based Routing (PBR): This feature allows you to route traffic based on specific criteria, such as source IP address, allowing you to apply different QoS policies to different types of traffic.
• Quality of Service (QoS) in VPN: This feature allows you to apply different QoS policies to VPN traffic, ensuring that VPN traffic is given the appropriate priority.
• Autosense feature: This feature allows the router to automatically adjust its QoS settings to match the type of traffic that is being sent and received.
• Link Fragmentation and Interleaving (LFI): This feature improves the performance of delay-sensitive traffic, such as voice and video, by fragmenting large packets and interleaving smaller packets with them.
