Description
Advanced Security Features
The Cisco ISR G2 1921 router with the C1921-3G-S-SEC/K9 model number includes advanced security features such as:
- Firewall (Cisco Adaptive Security Appliance (ASA)): The ASA firewall provides stateful and deep packet inspection capabilities to protect networks from external threats such as hackers, viruses, and malware. It also includes features such as access control lists (ACLs), virtual private networks (VPNs), and intrusion prevention systems (IPS).
- Intrusion Prevention System (IPS): This feature provides real-time detection and blocking of malicious network traffic, including known and unknown threats. It uses a combination of signature-based and anomaly-based detection methods to identify and prevent cyber-attacks.
- Virtual Private Network (VPN): The VPN feature enables secure remote access to the network for remote workers and partners. It supports various VPN protocols, such as IPsec, SSL, and L2TP, to provide secure and encrypted communication.
- Advanced Encryption Standard (AES): This feature provides strong encryption for sensitive data transmitted over the network. It uses the AES algorithm to encrypt data at the IP level, ensuring that it remains secure while in transit.
- Secure Shell (SSH): SSH is a secure protocol used to remotely access and manage devices on the network. It encrypts all data transmitted between the device and the SSH client, providing secure access to the command-line interface (CLI) of the router.
- Secure Sockets Layer (SSL): SSL is a security protocol used to establish secure connections over the internet. It is used to encrypt data transmitted between a web browser and a web server, protecting sensitive information such as login credentials.
- Network Address Translation (NAT): NAT is a technique used to translate private IP addresses to public IP addresses. It is used to hide internal IP addresses from the public internet, providing an additional layer of security for the network.
- Quality of Service (QoS): QoS is a feature that prioritizes different types of network traffic, such as voice and video, to ensure they are delivered with minimal delay and interruption.
- Secure boot: This feature verifies the integrity of the router’s firmware and prevents unauthorized firmware from being loaded.
- Secure firmware update: This feature provides secure and authenticated firmware updates to the router, ensuring that only authorized and verified firmware is installed.
- Cisco TrustSec for identity-based security: TrustSec enables security policies to be enforced based on the identity of users and devices, rather than just their network location. It allows administrators to create secure segments of the network and control access to sensitive resources, providing an additional layer of security to the network.
Performance and Scalability
The C1921-3G-S-SEC/K9 Cisco ISR G2 1921 router is designed for small to medium-sized businesses and enterprise branch offices. It offers high performance and scalability to support the growing demands of the network.
- Performance: The router is equipped with a powerful 1.3 GHz CPU, 1GB RAM and 256MB flash memory, which provide fast and efficient processing of network traffic. It also supports advanced routing protocols such as OSPF, EIGRP, and BGP, which allow for efficient and dynamic routing of network traffic.
- Scalability: The router supports up to 3 Gigabit Ethernet ports and 1 integrated 3G wireless WAN, and can be upgraded with additional interfaces as needed. This allows for easy expansion of the network to support more devices and users.
- Voice and Video : The router also supports Voice over IP (VoIP) and Video over IP (VoIP) services, which allows for efficient handling of voice and video traffic, while maintaining high quality of service.
- Security and QoS : The router supports advanced security features such as firewall, IPS, VPN, AES encryption, and Cisco TrustSec, and Quality of Service (QoS) features, which ensure that network traffic is prioritized and protected against security threats.
- Management : The router also includes Cisco IOS software, which provides a comprehensive set of network management tools, including a web-based GUI and command-line interface (CLI). This allows for easy configuration, monitoring, and troubleshooting of the network.
All these features make C1921-3G-S-SEC/K9 Cisco ISR G2 1921 Router a perfect fit for small to medium-sized businesses and enterprise branch offices, looking to provide a reliable and secure network infrastructure while keeping the cost and complexity low.
Management of Network Bandwidth
The C1921-3G-S-SEC/K9 Cisco ISR G2 1921 router includes several features that allow for the management of network bandwidth:
- Quality of Service (QoS): QoS allows for the prioritization of different types of network traffic, such as voice and video, to ensure they are delivered with minimal delay and interruption. It uses techniques such as traffic shaping, congestion management, and packet marking to manage network bandwidth and provide a consistent level of service to different types of network traffic.
- Traffic Shaping: Traffic shaping is a technique used to control the rate at which packets are sent and received on a network. It is used to limit the amount of bandwidth used by certain types of traffic, such as file transfers or video streaming, to ensure that other types of traffic, such as voice or real-time applications, have enough bandwidth to function properly.
- Congestion Management: Congestion management is a technique used to prevent network congestion by controlling the amount of traffic that is sent to a network. It uses techniques such as buffering and dropping packets to ensure that the network does not become overloaded.
- Packet Marking: Packet marking is a technique used to mark packets with a specific tag or priority level, allowing them to be treated differently by network devices such as routers and switches. This allows for the prioritization of certain types of traffic, such as voice or video, over other types of traffic.
- Bandwidth Control: Router supports bandwidth control on a per-interface basis, this allows you to control the amount of bandwidth that is available on each interface and to set limits on the amount of bandwidth that can be used by different types of traffic.
All these features allow for fine-grained control of network bandwidth, enabling administrators to ensure that critical applications and services receive the bandwidth they need, while also managing the overall usage of the network.
