A traceroute is a common troubleshooting tool to determine where traffic goes to reach it’s destination. traceroute will show the IP address or DNS name of hops between the source and destination. It will demonstrates how long it has taken to reach each hop three times, each measured in milliseconds. A traceroute will display an…

Ping is one of the most useful tools in network troubleshooting. Testing reachability using the ping command (ping 192.168.1.254) can quickly offer insight into any network issues On a Cisco router, a successful ping response will be marked with a !; a ping time out will be marked with a . The success rate is…

Cisco SD-WAN can offer connectivity, zero-trust security, end to end segmentation and application-aware quality of service into infrastructure-as-a-service environments with SD-WAN cloud routers. Cisco SD-WAN allows multiple connectivity methods to be used to extend the SD-WAN fabric into multiple public cloud environments over any underlay transport network.

Software-as-a-service applications reside on the Internet, and to achieve the best experience for the user, the best performing internet exit point needs to be used. When Cloud OnRamp is configured for a software-as-a-service application within vManage; the SD-WAN router at remote sites will probe the software-as-a-service application with small HTTP requests through each exit SD-Router…

Traditional WAN architectures are not designed for the cloud. As organisations adopt more cloud technologies such as Office 365, the existing traditional network provides more challenges with the level of complexity and end user expereience. Cisco SD-WAN includes a set of functionalities addressing optional cloud software-as-a-service application access and infrastructure-as-a-service connectivity called Cloud OnRamp. Cloud…

vAnalytics is an optional add-on to SDWAN that provides an optional analytics and assurance service. It can provide visibility into applications and infrastructure used across the WAN. vAnalytics can provide intelligent recommendations and forecasting.

vBond Orchestrator authenticates the vSmart controllers and the SD-WAN routers. It orchestrates connectivity between the vSmart controllers and the SD-WAN routers. The vBond Orchestrator is the only device that requires to have a public IP address on it so all other SD-WAN devices can connect to it. There are three components of the vBond Orchestrator:…

Cisco SD-WAN routers deliver the WAN, security, and multicloud capabilities of the SD-WAN architecture. The Cisco SD-WAN routers are available as hardware, software or cloud routers that sit at the perimeter of a site. SD-WAN routers support standard features such as OSPF, BGP, ACLs, QOS and other routing policies. In addition to the SD-WAN control…

vSmart controllers have preinstalled credentials that allow the controller to authenticate to every SD-WAN router that comes online. The credentials ensure that only authenticated devices can gain access to the SD-WAN fabric. After each successful authentication, the vSmart controller establishes a DTLS tunnel to each SD-WAN router in the fabric for uses these tunnels to…

The vManage NMS is a single pane of glass networking management system GUI that is used to configure and manage the SD-WAN solution. It provides centralised provisioning and managed network changes.
