Quality of Service (QoS) Features of the ISR4321/K9 Cisco ISR 4321 Router
The Cisco ISR4321/K9 is a security router that provides advanced routing and security services for small to medium-sized organizations. It also supports Quality of Service (QoS) features to help ensure that critical network traffic receives priority treatment over less important traffic.
Some of the QoS features available on the Cisco ISR4321/K9 include:
- Traffic classification and marking: The router can classify traffic based on a variety of criteria, such as source/destination IP address, protocol type, and port number. It can then mark traffic with a priority level, which is used to determine how the traffic should be treated by other QoS features.
- Congestion management: The router can use various congestion management techniques, such as queuing and scheduling, to ensure that high-priority traffic is transmitted before lower-priority traffic. This can help prevent network congestion and ensure that critical traffic is not delayed.
- Traffic shaping: The router can limit the amount of bandwidth that is available to certain types of traffic, ensuring that critical traffic always has enough bandwidth to meet its needs.
- Voice and video optimization: The router can prioritize voice and video traffic over other types of traffic. This can help ensure that real-time communication applications such as VoIP and video conferencing work smoothly and without interruption.
- These are just a few examples of the QoS features available on the Cisco ISR4321/K9. To configure and optimize QoS on your router, you should refer to the Cisco IOS Quality of Service Solutions Configuration Guide, which provides detailed instructions on how to configure QoS for various network scenarios.
