SD-WAN Access Interface Test

An Access Interface consisting of a Virtual Interface, WAN endpoint IP Address, Gateway IP Address, and Virtual Path Mode is defined collectively as an interface for a specific WAN link. The Access Interface defines the IP Address and Gateway IP Address for a WAN Link. At least one Access Interface is required for each WAN Link.

  • Virtual Interface – This is the Virtual Interface that the Access Interface will use. Select an entry from the drop-down menu of Virtual Interfaces configured for a branch site.
  • WAN endpoint IP Address – This is the IP Address for the Access Interface endpoint from the appliance to the WAN.
  • Gateway IP Address – This is the IP Address for the gateway router.
  • Virtual Path Mode – This specifies the priority for Virtual Path traffic on the WAN link. The options are: Primary, Secondary, or Exclude. If the Virtual Path Mode is set to Exclude, the Access Interface will be used for Internet and Intranet traffic, only.
  • Proxy ARP – If this option is enabled, the Virtual WAN Appliance replies to ARP requests for the Gateway IP Address, when the gateway is unreachable.

This test auto-discovers the access interfaces through which the connection is made to the target appliance and reports the traffic and throughput of each access interface.

Target of the test : A Citrix SD-WAN

Agent deploying the test : A remote agent

Outputs of the test : One set of results for every access interface connected to the target SD-WAN appliance.

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

Proxy ARP state

Indicates the current status of the Proxy ARP.

 

If the value of this measure is "Enabled", then the Virtual WAN Appliance replies to ARP requests for the Gateway IP Address, when the gateway is unreachable.

The numeric values that correspond to each of the above-mentioned values are as follows:

Measure Value Numeric Value
Disabled 0
Enabled 1

Note:

By default, this measure reports one of the Measure Values listed in the table above to indicate the current status of the proxy ARP. The graph of this measure however, represents the same using the numeric equivalents alone.

Reply age

Indicates the time taken to receive the response

Seconds

 

vPath packets received

Indicates the number of packets received over the this access interface's virtual path.

Packets

This measure is reported only when the Virtual Path Mode is set to Primary or Secondary.

Compare the values of these measures across the access interfaces to figure which access interface handled more packet traffic on the virtual path.

vPath packets transmitted

Indicates the number of packets transmitted over the this access interface's virtual path.

Packets

vPath data received

Indicates the amount of data received through the virtual path.

MB

These measures are reported only when the Virtual Path Mode is set to Primary or Secondary.

Compare the values of these measures across the access interfaces to figure which access interface transmitted and received data traffic on the virtual path.

vPath data transmitted

Indicates the amount of data transmitted through the virtual path.

MB

vPath input throughput

Indicates the rate at which the data was received over the virtual path.

Mbps

These measures are reported only when the Virtual Path Mode is set to Primary or Secondary.

The values of these measures help administrators to find out which access interface is most efficient in transmitting and receiving the data over the virtual path.

vPath output throughput

Indicates the rate at which the data was received over the virtual path.

Mbps

vPath compressed data received

Indicates the amount of compressed data received over the virtual path.

MB

These measures are reported only when the Virtual Path Mode is set to Primary or Secondary.

By comparing the values of these measures across the access interfaces, administrators can identify the access interface that received or transmitted the maximum amount of compressed data.

vPath compressed data transmitted

Indicates the amount of compressed data transmitted through the virtual path.

MB

Internet packets received

Indicates the number of packets received when this access interface uses Internet service for handling traffic.

Packets

This measure is reported only when the Virtual Path Mode is set to Exclude.

Internet packets transmitted

Indicates the number of packets transmitted when this access interface uses Internet service for handling traffic.

Packets

This measure is reported only when the Virtual Path Mode is set to Exclude.

Internet data received

Indicates the amount of data received when this access interface is used for handling Internet traffic.

MB

This measure is reported only when the Virtual Path Mode is set to Exclude.

Internet data transmitted

Indicates the amount of data transmitted when this access interface is used for handling Internet traffic.

MB

This measure is reported only when the Virtual Path Mode is set to Exclude.

Internet input throughput

Indicates the rate at which the incoming traffic processed when this access interface is used for handling Internet traffic.

Mbps

These measures are reported only when the Virtual Path Mode is set to Exclude.

The values of these measures help administrators to find out which access interface is most efficient in transmitting and receiving the data over the Internet.

Internet output throughput

Indicates the rate at which the outgoing traffic processed when this access interface is used for handling Internet traffic.

Mbps

Intranet packets received

Indicates the number of packets received when this access interface is used for handling Intranet traffic.

Packets

This measure is reported only when the Virtual Path Mode is set to Exclude.

Intranet packets transmitted

Indicates the number of packets transmitted when this access interface is used for handling Intranet traffic.

Packets

This measure is reported only when the Virtual Path Mode is set to Exclude.

Intranet data received

Indicates the amount of data received when this access interface is used for handling Intranet traffic.

MB

This measure is reported only when the Virtual Path Mode is set to Exclude.

Indicates the amount of data transmitted when this access interface is used for handling Intranet traffic.

MB

This measure is reported only when the Virtual Path Mode is set to Exclude.

Intranet input throughput

Indicates the rate at which the incoming traffic processed when this access interface is used for handling Intranet traffic.

Mbps

These measures are reported only when the Virtual Path Mode is set to Exclude.

The values of these measures help administrators to find out which access interface is most efficient in transmitting and receiving the data over the Intranet.
