Configuring dial-out telemetry

The dial-out telemetry configuration process includes the following elements:

sensor group
specifies one or more schema paths from which data is streamed to the collector
destination group
specifies the destination addresses (and ports) that the router uses to send the telemetry data
persistent subscription
associates a sensor group with a destination group and specifies streaming parameters for the telemetry data. For example, the subscription mode can be specified (ON_CHANGE, SAMPLE, or TARGET_DEFINED) for the subscription.

Dial-out telemetry can be configured via the MD-CLI or the classic CLI. For more information about using the MD-CLI, see the 7450 ESS, 7750 SR, and 7950 XRS MD-CLI User Guide. For more information about the MD-CLI configuration commands, see the 7450 ESS, 7750 SR, 7950 XRS, and VSR MD-CLI Command Reference Guide.

For more information about the classic CLI configuration commands, see the 7450 ESS, 7750 SR, 7950 XRS, and VSR Classic CLI Command Reference Guide and the 7450 ESS, 7750 SR, 7950 XRS, and VSR Clear, Monitor, Show, and Tools Command Reference Guide.

The following example shows a sample dial-out telemetry configuration in the MD-CLI:

[ex:/configure system telemetry]
A:admin@node-2# info
    destination-group "quick_cfg_dg_1" {
        description "Destination Group 1"
        allow-unsecure-connection
        destination 192.168.65.5 port 40001 {
            router-instance "Base"
        }
        destination 192.168.65.5 port 40002 {
            router-instance "Base"
        }
    }
    persistent-subscriptions {
        subscription "quick_cfg_sub_1" {
            admin-state enable
            description "Subscription 1"
            sensor-group "quick_cfg_sg"
            mode sample
            sample-interval 1234
            destination-group "quick_cfg_dg_1"
            local-source-address 1.2.3.4
            originated-qos-marking cp19
            encoding bytes
        }
    }
    sensor-groups {
        sensor-group "quick_cfg_sg" {
            description "Sensor Group"
            path "/state/router[router-name=Base]/interface[interface-name=test]/
statistics/ip" { }
        }
    }

The following sample outputs show telemetry information using the show command:
