Description
Network Monitoring and Management
Network monitoring and management of the Cisco ISR 4351-AXV/K9 router involves monitoring the router’s performance, status, and configuration. This can be done through both the command-line interface (CLI) and the web-based Cisco Integrated Management Controller (IMC) GUI.
Using the CLI, you can configure and monitor the router’s network settings, such as routing protocols, access control lists, and network interfaces. You can also use various show commands to view the status of different components of the router, such as the routing table, interface statistics, and system uptime.
The IMC GUI provides a more user-friendly interface for monitoring the router’s status and performance. It displays information such as device inventory, system health, and resource usage in a graphical format. The IMC also allows you to view and manage the router’s configuration, including network interfaces, routing protocols, and security settings.
Additionally, you can use various network management protocols, such as SNMP, NetFlow, and Cisco SD-WAN vManage to monitor and manage the router remotely. SNMP allows you to collect and monitor statistics on the router’s performance, such as CPU and memory usage. NetFlow can be used to monitor and analyze network traffic. Cisco SD-WAN vManage allows you to monitor and manage the SD-WAN feature of the router.
Managing Router Security
Managing router security for the Cisco ISR 4351-AXV/K9 router involves implementing various security measures to protect the router and the network it connects to from threats. Here are a few ways to manage router security:
- Access control: Configure access control lists (ACLs) to restrict access to the router’s management interface and network resources. This can be done by specifying which IP addresses or networks are allowed to access the router’s CLI or GUI.
- Authentication: Implement strong authentication mechanisms such as local username and password, or external RADIUS or TACACS+ servers to control access to the router’s management interface.
- Firewall: Configure firewall features such as stateful packet inspection (SPI) and intrusion detection and prevention (IDP) to protect the router and the network from malicious traffic.
- Encryption: Use encryption protocols such as IPsec or SSL to secure communications between the router and other network devices.
- Regularly update the software and firmware of the router to ensure that it is running the latest security patches and fix vulnerabilities.
- Regularly check the logs of the router for any suspicious activity and configure alerting mechanisms to notify you of any potential security breaches.
- Regularly review and audit the configuration of the router to ensure that it is configured in compliance with security best practices and company policies.
- Using VPN tunnels to encrypt sensitive data as it flows across the network.
Quality of Service (QoS) Capabilities
The Cisco ISR 4351-AXV/K9 router has Quality of Service (QoS) capabilities that allow you to prioritize and manage network traffic to ensure that critical applications receive the bandwidth they need to operate effectively. Here are a few of the QoS features of the ISR 4351-AXV/K9 router:
- Class-Based Weighted Fair Queuing (CBWFQ): Allows you to assign different levels of priority to different types of traffic, such as voice, video, and data, and to set a maximum bandwidth for each class of traffic.
- Low Latency Queuing (LLQ): Allows you to prioritize delay-sensitive traffic, such as voice and video, by giving it priority over other types of traffic.
- Weighted Random Early Detection (WRED): Allows you to manage network congestion by randomly dropping lower priority traffic when the router’s buffer becomes full.
- Policing and shaping: Enables you to limit the amount of traffic that enters or exits an interface, to ensure that only a certain amount of bandwidth is consumed by certain types of traffic.
- Multi-Field Classifier: Allows you to classify traffic based on various fields such as IP address, protocol, and port number.
- Quality of Service (QoS) Groups: Allows you to group similar traffic together and apply a QoS policy to that group.
- Cisco SD-WAN vManage: Allows you to monitor and manage the quality of service of the WAN link in real-time and also to apply policies and priorities to applications, devices, and users.
