One of the most critical factors of a successful SD-WAN implementation is the ability to retain data. This article will discuss how to configure and monitor IOS XE SD WAN nodes. This article also looks at the SD-WAN definition, the characteristics of SD-WAN nodes, and why data retention is necessary. Finally, it will give you an idea of keeping data as long as possible for the best performance. However, many other factors must be considered as well.
Data Retention is Critical to SD-WAN Performance
An SD-WAN can provide a better quality of service and response times by prioritizing traffic. This feature allows administrators to change the direction of traffic flows on different circuits. For example, voice and media traffic could be routed on a specific course, while internal applications might be given lower priority. In addition, high-bandwidth applications can be routed on a higher-capacity circuit. In this way, the organization can optimize its network bandwidth’s use without sacrificing service quality.
SD-WAN monitoring data must be interpreted based on the network’s structure and configuration. Fireware’s Web UI provides historical data for up to seven days. It also includes information on jitter calculations. In addition, SD WAN monitoring can help administrators understand why their network has many outages. The solution also provides visibility into the performance of different applications. By leveraging analytics and visibility, SD WANs can improve performance while cutting costs.
Organizations increasingly rely on cloud-based applications and services requiring faster WAN structures. However, most businesses do not have the resources to implement a traditional hardware-based WAN that routes traffic through a central hub. As a result, they turn to software-defined solutions to address these challenges. The software-defined WAN has several benefits, including increased security and availability. It also helps to improve performance and consistency.
Configuration of IOS XE SD-WAN Nodes
When configuring the IOS XE SD-WAN node, you need to understand how they work and what should be done to prevent failures. SD-WAN devices are a great way to extend your existing network, but you need to be careful to avoid making a mistake that could cause loss. A suitable SD-WAN controller should also provide alerts to help you avoid any issues. These alerts will tell you if there is a problem with the physical links. If the link is failing, traffic will be moved to another. However, this can affect other applications. Therefore, you may also need to run some low-level commands to prevent failure.
To configure an SD-WAN network connection, you need to know the IP address or port used to connect outside the network. This information is crucial for maintaining a healthy network. For this, you can use vBond as a STUN server. This allows other controllers and SD-WAN nodes to discover mapped IP addresses and translated port numbers.
To configure an IOS XE SD-WAN node for failure, you must set up a valid certificate on the SD-WAN edge router. Most hardware-based WAN Edge routers come with a certificate. To authenticate it, you can use a network time protocol. The system clock needs to be accurate for the certificate to work correctly. To configure an IOS XE SD-WAN node, you must set a one-time password and create permanent device certificates.
Monitoring of IOS XE SD-WAN Nodes
One way to monitor SD-WAN nodes is to use a tool that automatically generates reports on their health. This tool should send alerts for link failures or flapping links. It should also monitor jitter and packet loss. It should also be able to identify issues with a duplex mismatch, which is a common problem. It should also report daily on how the system performs to identify issues early.
You can monitor traffic loss by using the show app-route statistics command. It shows you the traffic loss of each application and site using a graph.
An essential aspect of monitoring SD-WAN performance is establishing the correct security policy. A valid certificate is required to authenticate the nodes. To prevent this, you must ensure that all your devices have a valid certificate. Most hardware-based WAN Edge routers come with certificates preinstalled at the factory. The system clock also needs to be accurate. This setting can be adjusted manually or through Network Time Protocol. However, this is a relatively rare issue when onboarding new devices. You can also use automated provisioning, which is also known as Plug-and-play.
