• In XPath expressions, select multiple keys by specifying them one after another. The following is an example of an XPath expression: /wireless-access-point-oper:access-point-oper-data/radio-oper-data/ radio-slot-id[wtp-mac="00:11:22:33:44:55"][radio-slot-id="1"] • XPath expressions support the use of the union operator (|) to allow a single subscription to support multiple objects. The union operator only works for NETCONF transport and not for gRPC. XPath Expressions Supported on Cisco Catalyst 9800 Wireless Controllers In Cisco IOS XE Bengaluru, 17.4.1, the following set of OpenConfig XPath expressions are supported on the Cisco Catalyst 9800 Series Wireless Controllers.
Ensure that you run the following RPC using any of the programmability interfaces, such as NETCONF, RESTCONF, or gNMI protocol, to enable telemetry subscription: xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="101"> xmlns="http://openconfig.net/yang/wifi/ap-manager"> eth_mac_of_the_AP eth_mac_of_the_AP AP_NAME All of the XPath expressions listed below are a part of the openconfig-access-points YANG model, except the last one, which is a part of the openconfig-ap-manager YANG model. For the telemetry operation to work correctly, ensure that configurations are done based on the OpenConfig model.
• /access-points/access-point/radios/radio/state • /access-points/access-point/radios/radio/neighbors/neighbor • /access-points/access-point/radios/radio/neighbors/neighbor/state • /access-points/access-point/ssids/ssid/bssids/bssid/state/counters • /access-points/access-point/ssids/ssid/clients/client/state/counters • /access-points/access-point/ssids/ssid/clients/client/client-rf/state • /access-points/access-point/ssids/ssid/clients/client/client-connection/state • /access-points/access-point/system/aaa/server-groups/server-group/servers/server/radius/state • /joined-aps/joined-ap/state/opstate When you subscribe to an XPath, you receive data for the subscribed XPath and all the XPaths under it in the hierarchy.
For example, subscribing to /access-points/access-point/radios/radio/state delivers data for all the leaves associated with it, as well as the subcontainers under it. Model-Driven Telemetry XPath Expressions Supported on Cisco Catalyst 9800 Wireless Controllers Model-Driven Telemetry 35
