Telemetry subscription receivers detail:

  Subscription ID: 222
  Address: 192.168.46.20
  Port: 8014
  Protocol: cloud-native
  Profile: 
  Connection: 32037
  State: Connected
  Explanation:

The switch has five different subscriptions ranging from 222-227 which can be used as the Subscription ID. Check if the Address is the IP address of the Cisco Spaces: Connector. Also check if the State is Connected.

What commands are run on the switch?

When a switch port status changes to UP, Cisco Spaces: Connector polls the switch for any potential switch port identity information. The connector executes the NETCONF GET command, which is similar to the show dot1x interface GigabitEthernet 1/0/1 details command.

Below is the output of the NETCONF command.

<filter xmlns=\"urn:ietf:params:xml:ns:netconf:base:1.0\">
    <identity-oper-data xmlns=\"http://cisco.com/ns/yang/Cisco-IOS-XE-identity-oper\">
        <session-context-data>
            <intf-iifid>___interface_index___</intf-iifid>
        </session-context-data>
    </identity-oper-data>
</filter>

Below is the output of the NETCONF command.
