The ISR4321-SEC/K9 Cisco ISR 4321 Security Router provides several methods for managing network bandwidth. Some of these methods include:

• Quality of Service (QoS) policies: QoS policies allow you to define a set of rules for managing and prioritizing traffic. You can use these policies to ensure that mission-critical applications receive the necessary bandwidth.
• Traffic policing and shaping: Traffic policing and shaping allow you to limit the amount of bandwidth that a particular type of traffic can consume. This can be used to ensure that high-priority traffic is not impacted by lower-priority traffic.
• Link Efficiency Mechanism (LEM): LEM is used to improve link efficiency by compressing the traffic and reducing the amount of data that needs to be transmitted over the network. This can help to free up bandwidth for other applications.
• Access Control Lists (ACLs): ACLs can be used to control the amount of traffic that is allowed to enter or exit the router. This can be used to limit the amount of bandwidth that is consumed by certain types of traffic.
• Quality of Service (QoS) queues: The router supports multiple queues, which can be used to prioritize different types of traffic. This can help to ensure that high-priority traffic is not impacted by lower-priority traffic.
• Bandwidth Management: The router allows you to allocate the bandwidth to different interfaces, this way you can ensure that the critical applications or VLANs have the necessary bandwidth and that the non-critical applications do not consume too much.
• Cisco's Application Visibility and Control (AVC): AVC is a feature that allows you to monitor and control the bandwidth usage of specific applications. This can be used to ensure that bandwidth-intensive applications do not consume too much bandwidth.
• Cisco's Network-Based Application Recognition (NBAR): NBAR is a feature that allows you to identify and classify different types of traffic, which can be used to ensure that high-priority traffic is not impacted by lower-priority traffic.

The ISR4321-SEC/K9 Cisco ISR 4321 Security Router supports several remote management protocols, including:

• SSH (Secure Shell) is a network protocol that allows for secure remote access to a device's command-line interface. It encrypts all data exchanged between the client and the server, ensuring that sensitive information, such as login credentials, is protected from eavesdropping. SSH is the recommended method for remotely accessing the ISR4321-SEC/K9's command-line interface.
• Telnet is a network protocol that allows for remote access to a device's command-line interface. However, unlike SSH, it does not encrypt the data exchanged between the client and the server, making it vulnerable to eavesdropping and other security risks. It is not recommended to use Telnet for remote access to the ISR4321-SEC/K9's command-line interface.
• SNMP (Simple Network Management Protocol) is a standard protocol used for monitoring and managing network devices. It allows network administrators to monitor the performance and status of network devices, such as the ISR4321-SEC/K9, and to receive alerts when certain thresholds are exceeded.
• HTTP and HTTPS are protocols used for accessing web-based management interfaces. HTTP is unencrypted, while HTTPS encrypts the communication between the client and the server, providing an added layer of security.
• SCP (Secure Copy Protocol) is a protocol that allows for the secure transfer of files to and from a remote device. It encrypts the data being transferred and requires authentication, making it a secure method for transferring sensitive information to and from the ISR4321-SEC/K9.

Advanced Security Features

The ISR4321-SEC/K9 Cisco ISR 4321 Security Router is a powerful security device that offers a wide range of advanced security features to protect your network. Some of the key features include:
