Discovery and Service Mapping Patterns finds Azure Express Route Circuit resources on your cloud environment. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

## Pattern-based discovery and mapping requirements {#azure-express-route-circuit-pattern__section_rpj_fj2_bgc}

Verify the Azure discovery prerequisites section in [Microsoft Azure Cloud components discovery using patterns](https://servicenow-prod.fluidtopics.net/JeDZ0tlC9eLF5fei5qSv3w "Discovery uses multiple patterns to discover components of the Microsoft Azure Cloud deployment during horizontal discovery. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.").

## Data collected by Discovery during horizontal discovery {#azure-express-route-circuit-pattern__section_ggp_ql2_bgc}

Discovery populates the data in the CMDB when running the Azure - Express Route Circuit (LP) pattern.  
{#azure-express-route-circuit-pattern__table_mkf_2hc_dgc__entry__2}

| Field | Description |
|-|-|
| Object ID \[object_id\] | The unique Azure resource identifier for the Express Route Circuit. |
| Name \[name\] | The name of the Express Route Circuit. |
| State \[state\] | The current state of the Express Route Circuit. |
| VLAN ID \[vlanid\] | The Virtual LAN (VLAN) identifier assigned to the Express Route Circuit. |
