Synchronization timing between Catalyst Center and Wireless Controler

[iferras]

We are interested on using Catalyst Center "clients" API (/dna/data/api/v1/clients) for getting information about clients associated to a connected Wireless Controller. The API may take between 30 seconds and 4 minutes to show changes. Could you give some insight on the reason for this variability? Can this timing be adjusted to a shorter refresh period?

Thank you very much in advance,

Ignasi

This is unfortunately not something you can change, if you need real time data you will need to fetch it directly from your WLC.

Thank you very much. What would be the equivalent to fecht client information from the WLC (C9800-40-K9)?

You would probably want to use SNMP, netconf or restconf for this. MDT over gRPC is also an option if you want to go down that route. For Netconf/Restconf this is the module you want to use: https://github.com/YangModels/yang/blob/main/vendor/cisco/xe/1791/Cisco-IOS-XE-wireless-client-oper.yang
