SD-WAN Routes Test

In a typical SD-WAN network, the branch offices access applications on the on-premises data center, the cloud data center, or the SaaS applications. The application routing feature of the target SD-WAN appliance, allows you to steer the applications through your network easily and cost-efficiently. For example, when a user on the branch site is trying to access a SaaS application, the traffic can be routed such that the branch offices can access the SaaS applications on the internet directly, without having to go through the data center first. In such a way, users can have quick access to the applications and better experience with the applications. To perform the effective routing in the SD-WAN environment, it is necessary that the routing IP should be able to reach the network easily and eligible to transmit the requests over the network. Whenever any of the routing IP addresses is not able to steer the application traffic over the network, administrators may want to identify the exact technical glitch that caused the issue. This is where the SD-WAN Routes test helps administrators!

This auto-discovers all routing IP addresses that are transmitting the requests via the target appliance, and for each IP address, reports the network reachability and eligibility.

Target of the test : A Citrix SD- WAN

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each service:routing IP address.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed. By default, this is set to 5 minutes.

Host

The IP address of the target SD-WAN appliance for which this test is to be configured.

Port

Refers to the port at which the target SD-WAN listens to. By default, this will be NULL.

Timeout

Specify the time duration (in seconds) beyond which this test should time out in the Timeout text box. The default is 10 seconds.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Is network reachable?

Indicates whether this route IP address is able to reachable or not.

 

The numeric values that correspond to measure values are as follows:

Measure Value Numeric Value
No 0
Yes 1

Note:

By default, this measure reports one of the Measure Values listed in the table above to indicate whether each route IP address is reachable or not. The graph of this measure however, represents the same using the numeric equivalents alone.

Route type

Indicates the route type of this IP address.

 

The numeric values that correspond to measure values are as follows:

Measure Value Numeric Value
Static 0
Dynamic 1

Note:

By default, this measure reports one of the Measure Values listed in the table above to indicate the type of each IP address. The graph of this measure however, represents the same using the numeric equivalents alone.

Is eligible?

Indicates whether/not this IP address is eligible to transmit requests.

 

The numeric values that correspond to measure values are as follows:

Measure Value Numeric Value
No 0
Yes 1

Note:

By default, this measure reports one of the Measure Values listed in the table above to indicate whether the IP address is reachable or not. The graph of this measure however, represents the same using the numeric equivalents alone.

Hits

Indicates the number of times this IP address used to steer the application traffic.

Number

 

Cost

Indicates the weight for determining the route priority of this IP address.

Number

The value of this measure may vary from 1 to 15. Typically, lower-cost routes take precedence over higher-cost routes. The default value is 5.
