how to obtain interface input / output values

OaklandCounty_Mike — Wed, 22 Sep 2021 02:29:13 GMT

Hello,

At times I need to check my 9300 Edge switches for unused interfaces so that i can either disable them or re-purpose them when they go under utilized. typically i would check the input and out values and typically look for interfaces that have a output of "never".

after using the interface rest api call from DNAC or directly against a switch, this type of data does not seem to be present. is there a way to obtain dynamically via a REST API call?

@OaklandCounty_Mike you could use tools like Netmiko, Napalm, Scrapli over SSH/Netconf. PyATS is a very popular choice too https://developer.cisco.com/pyats/ You can also do this with YANG, see https://developer.cisco.com/yangsuite/ to get started here.

Hope this helps.

Thank you for your reply, I was hoping to not have to do it via a SSH connection. Maybe we will get rest api soon to provide this info.
Have a good day!

@OaklandCounty_Mike you could use RESTCONF https://content.cisco.com/chapter.sjs?uri=/searchable/chapter/content/en/us/td/docs/ios-xml/ios/prog/configuration/167/b_167_programmability_cg/restconf_programmable_interface.html.xml&platform=Cisco%20Catalyst%209300%20Series%20Switches
