ExpressRoute, which extends an on-premises network into the Microsoft cloud over a private connection that is facilitated by a connectivity provider, involves the following three distinct network zones:. The purpose of this document is to help user to identify where or even if a connectivity issue exists and within which zone, thereby to seek help from appropriate team to resolve the issue. If Microsoft support is needed to resolve an issue, open a support ticket status recovery bot config router Microsoft Support.

This document is intended to help diagnosing and fixing simple issues. It is not intended to be a replacement for Microsoft support. Open a support ticket with Microsoft Support if you are unable to solve the problem using the guidance provided.

The following diagram shows the logical connectivity of a customer network to Microsoft status recovery bot config router using ExpressRoute. In the preceding diagram, the numbers indicate key network points. The network points are referenced often through this article by their status recovery bot config router number. The key network points illustrated are as follows:. Network points 3 and 4 would still exist but be somewhat transparent as Layer 2 devices.

A redundant pair of network paths is also encouraged between customer network and PE-CEs. To validate an ExpressRoute circuit, the following steps are covered with the network point indicated by the associated number:.

Regardless of the connectivity model, an ExpressRoute circuit has to be created and thus a service key generated for circuit provisioning. For more information on how to create, modify, provision, and verify an ExpressRoute circuit, see the article Create and modify an ExpressRoute circuit.

A service key uniquely identifies an ExpressRoute circuit. This key is required for most of the powershell commands mentioned in this document. Also, should you need assistance from Microsoft or from an ExpressRoute partner to troubleshoot an ExpressRoute issue, provide the service key to readily identify the circuit. In the Azure portal, the status of an ExpressRoute circuit can be checked by selecting on the left-side-bar menu and then selecting the ExpressRoute circuit.

In the section of the blade, the ExpressRoute essentials are listed as shown in the following screen shot:. In the ExpressRoute Essentials, Circuit status indicates the status of the circuit on the Microsoft side.

For an ExpressRoute circuit to status recovery bot config router operational, the Circuit status recovery bot config router must be Enabled and the Provider status must be Provisioned. If the Circuit status is not enabled, contact Microsoft Support. If the Provider status is not provisioned, contact your service provider.

You status recovery bot config router get your resource group name through the Azure. See the previous subsection of this document and note that the resource group name is listed in the example screen shot. To confirm if an ExpressRoute circuit is operational, pay particular attention to the following fields:. If the ServiceProviderProvisioningState is not provisioned, contact your service provider.

To confirm if an ExpressRoute circuit is operational, pay particular attention to the following fields: If the Status is not enabled, contact Microsoft Support. Each ExpressRoute circuit can have one, two, or three routing contexts enabled: Azure private peering traffic to private virtual networks status recovery bot config router AzureAzure public peering traffic to public IP addresses in Azureand Microsoft peering traffic to Office and Dynamics For more information on how to create and modify routing configuration, see the article Create and modify routing for an ExpressRoute circuit.

If layer 3 is provided by the service provider and the peerings are blank in the portal, refresh the Circuit configuration using the refresh button on the protal.

This operation will apply the right routing configuration on your circuit. In the Azure portal, status of an ExpressRoute circuit can be checked by selecting on the left-side-bar menu and then selecting the ExpressRoute circuit.

Selecting an ExpressRoute circuit listed under "All resources" would open the ExpressRoute circuit blade. In the section of the blade, the ExpressRoute essentials would be listed as shown in the following screen shot:. In the preceding example, as noted Azure private peering routing context is enabled, whereas Azure public and Microsoft peering routing contexts are not enabled.

A successfully enabled peering context would also have the primary and secondary point-to-point required for BGP subnets listed. A successfully enabled peering context would have the primary and secondary address prefixes listed.

If a peering is not configured, there would be an error message. A sample response, when the stated peering Azure Public peering in this example is not configured within the circuit:. If a peering is not enabled, check if the primary and secondary subnets assigned match the configuration on the linked PE-MSEE.

A successfully, enabled peering context would have the primary and secondary peer subnets listed. If layer 3 peerings were set by the service provider, setting the ExpressRoute peerings via the portal or PowerShell overwrites the service provider settings. Status recovery bot config router the provider side peering settings requires the support of the service provider.

Only modify the ExpressRoute peerings if it is certain that the service provider is providing layer 2 services only! If a peering is not enabled, check if the primary and secondary peer subnets assigned match the configuration on the linked Status recovery bot config router. This section uses PowerShell Classic commands. To get the routing table BGP neighbor status recovery bot config router for a particular routing context, use the following command:.

Status recovery bot config router shown in the preceding example, the command is useful to determine for how long the routing context has been established. It also indicates number of route prefixes advertised by the peering router. If certain destinations are not reachable over a particular peering, check the status recovery bot config router table of the MSEEs belonging to the particular peering context.

To get the status recovery bot config router routing table from MSEE on the Primary path for the particular Private routing context, use the following command:.

To get the combined primary and secondary path traffic statistics--bytes in and out--of a peering context, use the following command:. Our new feedback system is built on GitHub Issues.

Azure Traffic Manager includes built-in endpoint monitoring and automatic endpoint failover. This feature helps you deliver high-availability applications that are resilient to endpoint failure, including Azure region failures.

To configure endpoint monitoring, you must specify the following settings on your Traffic Manager profile:. If it gets back a OK response, then that endpoint is considered healthy. If the response is a different value, or, if no response is received within the timeout period specified, then the Traffic Manager probing agent re-attempts according to the Tolerated Number of Failures setting no re-attempts are done if this setting is 0.

If the number of consecutive failures is higher than the Tolerated Number of Failures setting, then that endpoint is marked as unhealthy. If the endpoint responds to the request with a response to establish the connection, that health check is marked as a success and the Traffic Manager probing agent resets the TCP connection.

If the response is a different value, or if no response is received within the timeout period specified, the Traffic Manager probing agent re-attempts according to the Tolerated Number of Failures setting no re-attempts are made if this setting is 0.

If the number of consecutive failures is higher than the Tolerated Number of Failures setting, then that endpoint is marked unhealthy. In all cases, Traffic Manager probes from multiple locations and the consecutive failure determination happens within each region. This also means that endpoints are receiving health probes from Traffic Manager with a higher frequency than the setting used for Probing Interval. Using this path for monitoring, you can perform application-specific checks, such as checking performance counters or verifying database availability.

Based on these custom checks, the page returns an appropriate HTTP status code. All endpoints in a Traffic Manager profile share monitoring settings. If you need to use different monitoring settings for different endpoints, you can create nested Traffic Manager profiles. You can enable and disable Traffic Manager profiles and endpoints. However, a change in endpoint status also might occur as a result of Traffic Manager automated settings and processes. You can enable or disable a specific endpoint.

The underlying service, which might still be healthy, is unaffected. Changing the endpoint status controls the availability of the endpoint in the Traffic Manager profile. When an endpoint status is disabled, Traffic Manager does not check its health and the endpoint is not included in a DNS response. Using the profile status setting, you can enable or disable a specific profile.

While endpoint status affects a single endpoint, profile status affects the entire profile, including all endpoints. When you disable a profile, the endpoints are not checked for health and no endpoints are included in a DNS response.

Endpoint monitor status is a Traffic Manager-generated value that shows the status of the endpoint. You cannot change this setting manually. The endpoint monitor status is a combination of the results of endpoint monitoring and the configured endpoint status.

The possible values of endpoint monitor status are shown in the following table:. For details about how endpoint monitor status is calculated for nested endpoints, see nested Traffic Manager profiles. A Stopped Endpoint monitor status can happen on App Service if your web application is not running in the Standard tier or above. For more information, see Traffic Manager integration with App Service.

The profile monitor status is a combination of the configured profile status and the endpoint monitor status values for all endpoints. The possible values are described in the following table:. Traffic Manager periodically checks the health of every endpoint, including unhealthy endpoints. Traffic Manager detects when an endpoint becomes healthy and brings it back into rotation.

For more information about troubleshooting failed checks, see Troubleshooting Degraded status on Azure Traffic Manager. The following timeline in Figure 2 is a detailed description of the monitoring process of Traffic Manager endpoint that has the following settings: Traffic to service resumes. The service has returned to a healthy state. Traffic returns to the endpoint as cached DNS responses that return other endpoints expire, and as existing connections to other endpoints are terminated.

Because Traffic Manager works at the DNS level, it cannot influence existing connections to any endpoint. When it directs traffic between endpoints either by changed profile settings, or during failover or failback , Traffic Manager directs new connections to available endpoints.

However, other endpoints might continue to receive traffic via existing connections until those sessions are terminated. To enable traffic to drain from existing connections, applications should limit the session duration used with each endpoint. When an endpoint has a Degraded status, it is no longer returned in response to DNS queries. Instead, an alternative endpoint is chosen and returned.

The traffic-routing method configured in the profile determines how the alternative endpoint is chosen.

For more information, see Traffic Manager traffic-routing methods. One exception to normal traffic-routing behavior occurs when all eligible endpoints have a degraded status. Traffic Manager makes a "best effort" attempt and responds as if all the Degraded status endpoints actually are in an online state. This behavior is preferable to the alternative, which would be to not return any endpoint in the DNS response. Disabled or Stopped endpoints are not monitored, therefore, they are not considered eligible for traffic.

The consequence of this behavior is that if Traffic Manager health checks are not configured correctly, it might appear from the traffic routing as though Traffic Manager is working properly. However, in this case, endpoint failover cannot happen which affects overall application availability. It is important to check that the profile shows an Online status, not a Degraded status. An Online status indicates that the Traffic Manager health checks are working as expected. For more information about troubleshooting failed health checks, see Troubleshooting Degraded status on Azure Traffic Manager.

Configure endpoint monitoring To configure endpoint monitoring, you must specify the following settings on your Traffic Manager profile: Choose the port used for the request. Providing this setting for the TCP monitoring protocol results in an error. For TCP protocol, give the relative path and the name of the webpage or the file that the monitoring accesses. This value implies that the file is in the root directory default. This value specifies how often an endpoint is checked for its health from a Traffic Manager probing agent.

You can specify two values here: If no values are provided, the profile sets to a default value of 30 seconds. Visit the Traffic Manager Pricing page to learn more about fast probing pricing. Tolerated Number of Failures. This value specifies how many failures a Traffic Manager probing agent tolerates before marking that endpoint as unhealthy.

Its value can range between 0 and 9. A value of 0 means a single monitoring failure can cause that endpoint to be marked as unhealthy. If no value is specified, it uses the default value of 3. This property specifies the amount of time the Traffic Manager probing agent should wait before considering that check a failure when a health check probe is sent to the endpoint. If the Probing Interval is set to 30 seconds, then you can set the Timeout value between 5 and 10 seconds.

If no value is specified, it uses a default value of 10 seconds. If the Probing Interval is set to 10 seconds, then you can set the Timeout value between 5 and 9 seconds.

If no Timeout value is specified, it uses a default value of 9 seconds. Note A Stopped Endpoint monitor status can happen on App Service if your web application is not running in the Standard tier or above. Note One exception to normal traffic-routing behavior occurs when all eligible endpoints have a degraded status.

This condition is commonly caused by improper configuration of the service, such as: An improper configuration of the monitoring port or protocol in the Traffic manager profile.

The profile has been disabled. Although the endpoint status is Enabled, the profile status Disabled takes precedence. Endpoints in disabled profiles are not monitored. The endpoint has been disabled. Disabled endpoints are not monitored. The endpoint is not included in DNS responses, therefore, it does not receive traffic.

The endpoint is monitored and is healthy. It is included in DNS responses and can receive traffic. Endpoint monitoring health checks are failing. The endpoint is not included in DNS responses and does not receive traffic. An exception to this is if all endpoints are degraded, in which case all of them are considered to be returned in the query response.
