Issue/Introduction
In-band Network Telemetry is a feature that can be enabled to allow Traceflow on VLAN-backed NSX Segments. This article describes disabling the feature if desired.
Environment
VMware NSX
VMware NSX-T
Cause
Traceflow is no longer required on VLAN-backed NSX segments and you want to turn off the feature.
Resolution
- First use the API GET https://<ManagerIP>/policy/api/v1/infra/ops-global-config call to retrieve the current configuration.
Example output:
{
"operation_collectors": [
{
"report_interval": 30,
"collector_type": "VRNI",
"collector_ip": "###.###.###.###",
"collector_port": ####
}
],
"in_band_network_telementry": {
"dscp_value": 2,
"indicator_type": "DSCP_VALUE"
},
"operation_feature_disabled": {
"latency_stat_disabled": false,
"live_trace_disabled": false
},
"is_inherited": false,
"site_infos": [],
"resource_type": "OpsGlobalConfig",
"id": "ops-global-config",
"display_name": "ops-global-config",
"path": "/infra/ops-global-config",
"relative_path": "ops-global-config",
"parent_path": "/infra",
"remote_path": "",
"unique_id": "########-####-####-####-############",
"realization_id": "########-####-####-####-############",
"owner_id": "########-####-####-####-############",
"marked_for_delete": false,
"overridden": false,
"_system_owned": false,
"_protection": "NOT_PROTECTED",
"_create_time": 1764727579090,
"_create_user": "system",
"_last_modified_time": 1767739227089,
"_last_modified_user": "#####",
"_revision": 10
}
Note the VRNI collector above is an example. Depending on your NSX deployment there may be different fields listed in the GET output. - Modify the output of the GET to remove the "in_band_network_telementry" section.
Example:
{
"operation_collectors": [
{
"report_interval": 30,
"collector_type": "VRNI",
"collector_ip": "###.###.###.###",
"collector_port": ####
}
],
"operation_feature_disabled": {
"latency_stat_disabled": false,
"live_trace_disabled": false
},
"is_inherited": false,
"site_infos": [],
"resource_type": "OpsGlobalConfig",
"id": "ops-global-config",
"display_name": "ops-global-config",
"path": "/infra/ops-global-config",
"relative_path": "ops-global-config",
"parent_path": "/infra",
"remote_path": "",
"unique_id": "########-####-####-####-############",
"realization_id": "########-####-####-####-############",
"owner_id": "########-####-####-####-############",
"marked_for_delete": false,
"overridden": false,
"_system_owned": false,
"_protection": "NOT_PROTECTED",
"_create_time": 1764727579090,
"_create_user": "system",
"_last_modified_time": 1767739227089,
"_last_modified_user": "#####",
"_revision": 10
}
- Use this edited API body in a
PUT https://<ManagerIP>/policy/api/v1/infra/ops-global-config - Confirm the in_band_network_telementry field has been removed by running the original API GET call and confirming the field is no longer included in the response.
