Physical Interfaces Health Check Results

The Physical Interfaces accordion displays the physical interface components on the PE devices that the VPN services span through.

To access the Physical Interfaces accordion:

  1. Navigate to the Orchestration > Instances > Service Instances page.

  2. Select a service instance and click the service-instance-name hyperlink to access the Service-Instance-Name Details page

  3. Click the Passive Assurance tab.

  4. Click and expand the Physical Interfaces accordion.

Table 1 lists the fields in the Physical Interfaces table.

Note:

KPI-related data may not be displayed in the accordion tables and on the graphs when:

  • There are device errors.

  • The data displayed is derived from or is dependent on another KPI which is not being streamed by the devices.

To view details of health check results for physical interface parameters, click any hyperlinked entry in the Physical Interfaces table to open the corresponding accordion on the Physical Interfaces Details for service-instance-name page.

Table 1: Fields in the Physical Interfaces Table

Field

Description

Device Name

Name of the PE device to which the physical interface belongs.

Interface Name

Name of the physical interface. For example, et-0/0/1.

Input Util

The input bandwidth utilization on the interface.

Output Util

The output bandwidth utilization on the interface.

Flaps

The number of link flaps on the interface.

Input Errors Count

The number of errors in packets received by the interface.

Output Errors Count

The number of errors in packets sent by the interface.

Admin State

The administrative state of the physical interface:

  • Up—The interface is active and can send and receive network traffic.

  • Down—The interface is inactive and does not send and receive network traffic. An interface is inactivated by the network administrator for reasons such as troubleshooting and maintenance.

Link State

The link state of the physical interface:

  • Up—The interface physical link is functional and network traffic can be sent or received by the interface.

  • Down—The interface physical link is not functional and the interface cannot transmit network traffic.

Speed

The interface speed or the maximum data transmission rate that the interface supports.

View Health Check Results for Physical Interface Parameters

The Physical Interfaces Details for service-instance-name page displays the health check results of the physical interface parameters, categorized into accordions. View the name of the physical interface for which the health check results are displayed and the name of the PE device to which the physical interface belongs at the top of the page. The accordion heading displays the parameter name, alerts generated for the parameter, and a condensed view of the performance graph displaying the health and functioning of the interface parameter.

To view the health check results of an interface parameter in detail, expand the corresponding accordion. The accordion displays the performance graph for the parameter. For more information about performance graphs, see Performance Graphs to View Passive Assurance Monitoring Data.

Table 2 lists the accordions on the Physical Interfaces Details for service-instance-name page.
