CGR1120/K9 Cisco 1120 Modular Gigabit Ethernet Router Refurbished

The CGR1120/K9 Cisco 1120 Modular Gigabit Ethernet Router is a high-performance router that offers advanced security features to help protect networks against a wide range of security threats. Some of the key advanced security features of the CGR1120/K9 include:

• Firewall: The CGR1120/K9 features a stateful firewall that can help protect networks against unauthorized access and other security threats. The firewall can be configured to allow or block specific traffic based on a wide range of criteria, including source and destination IP addresses, ports, and protocols.
• Intrusion Detection and Prevention (IDP): The CGR1120/K9 includes an IDP system that can detect and prevent a wide range of security threats, including malware, worms, and other malicious traffic. The IDP system can be configured to take specific actions, such as blocking traffic or alerting administrators, when a security threat is detected.
• Virtual Private Network (VPN): The CGR1120/K9 includes support for a wide range of VPN protocols, including IPsec, SSL, and L2TP. This allows networks to establish secure, encrypted connections between remote locations and the main network, helping to protect against eavesdropping and other security threats.
• Advanced Malware Protection (AMP): The CGR1120/K9 includes AMP technology that can detect and block malware in real-time, using threat intelligence and machine learning. This can help protect networks against emerging threats and zero-day attacks.
• Access Control Lists (ACLs): The CGR1120/K9 can be configured to apply access control lists (ACLs) to specific interfaces, allowing network administrators to control which devices and users are allowed to access the network.
• Identity-based security: The CGR1120/K9 supports Identity-based security which allows network administrators to control access based on user credentials and roles. This can help protect against unauthorized access and other security threats.
• Secure boot: The CGR1120/K9 is equipped with a secure boot feature which verifies the integrity of the router's firmware at startup and prevents unauthorized firmware from running on the router.

Configuring and managing the CGR1120/K9 Cisco 1120 Modular Gigabit Ethernet Router involves setting up and managing the various components and settings of the router to ensure that it is properly configured and optimized for the specific needs of the network. This can include configuring the router's interfaces, setting up routing protocols, and managing the various services that are running on the router.

One of the key components of configuring and managing the CGR1120/K9 is the ability to configure the router's interfaces. This can include setting up and configuring physical interfaces, such as Ethernet and serial ports, as well as virtual interfaces, such as virtual LANs (VLANs) and virtual private networks (VPNs). This can be done using a variety of tools and techniques, including web-based interfaces, command-line interfaces, and remote management protocols.

Another important aspect of configuring and managing the CGR1120/K9 is the ability to set up and manage routing protocols. This can include configuring routing protocols such as Open Shortest Path First (OSPF), Routing Information Protocol (RIP), and Border Gateway Protocol (BGP) to ensure that the router is able to properly route traffic within the network.

In addition, the CGR1120/K9 management includes the management of various services that are running on the router. This can include configuring and managing services such as Quality of Service (QoS), access control lists (ACLs), and security features such as firewalls and intrusion detection systems (IDS). This can be done using a variety of tools and techniques, including web-based interfaces, command-line interfaces, and remote management protocols.

The CGR1120/K9 also has the capability to support modularity, this means that it can be customized to meet the specific needs of the network. This can include adding new interfaces or services, such as wireless or VPN capabilities, as well as upgrading the router's hardware or software to improve performance or add new features.

The CGR1120/K9 Cisco 1120 Modular Gigabit Ethernet Router has a range of advanced networking capabilities that allow it to handle complex network environments and provide high-performance routing and switching capabilities. Some of these advanced capabilities include:

• Gigabit Ethernet interfaces: The CGR1120/K9 has a total of 8 Gigabit Ethernet ports that can be configured as LAN or WAN interfaces. This allows for high-speed connectivity to other network devices and the ability to handle large amounts of traffic.
• Virtual Routing and Forwarding (VRF): The CGR1120/K9 supports VRF, which allows for multiple virtual routing tables to be created and maintained on the router. This allows for the creation of separate virtual networks within the same physical network infrastructure.
• Quality of Service (QoS): The CGR1120/K9 has advanced QoS capabilities that allow for the prioritization of different types of traffic based on various criteria such as IP address, port number, and protocol. This ensures that critical traffic such as voice and video is given priority over other traffic.
• Security: The CGR1120/K9 has a range of security features including firewalls, intrusion prevention, and VPN capabilities. This allows for the creation of secure connections between remote networks and the ability to protect the network from external threats.
• MPLS: The CGR1120/K9 supports Multi-Protocol Label Switching (MPLS), which allows for the creation of virtual private networks (VPNs) over the public Internet. This allows for the creation of secure, high-performance connections between remote sites.
• IPv6: The CGR1120/K9 supports IPv6, which allows for the use of the next-generation Internet Protocol. This allows for the use of longer IP addresses and provides the ability to handle a larger number of devices on the network.
• High-availability: The CGR1120/K9 supports high-availability features such as Hot Standby Router Protocol (HSRP) and Virtual Router Redundancy Protocol (VRRP) that allow for the creation of redundant network connections to ensure that the network remains up and running even in the event of a failure.
