Ping RPC error with Cisco_IOS_XR_ping_act module

Hello guys,

I see that while using the Cisco_IOS_XR_ping_act module for performing ping tests, the router sets the rpc output field rotate-pattern to a numerical value (0 in my case) , but the yang model/python class expects a boolean value. I am not sure whether the yang model is incorrect or the router is returning a rogue value. Can anyone please confirm.

Thanks,

Mufaddal

You are correct. The rotate-pattern should have a boolean value. This is an open bug in XR CSCvh50220. It should be fixed soon.

Thank you for the quick response, I think the bug is currently not externally visible

Another related question , is there any other way to do a ping operation for a XR box ?

Please find below a python script which should help you with this:

First:

pip install ncclient

Use below payload:

pl='''<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="101"><ping xmlns="http://cisco.com/ns/yang/Cisco-IOS-XR-ping-act"> 

  <destination>

    <destination>172.16.1.12</destination>

  </destination>

</ping>

</rpc>  '''



Then run below script:

from ncclient.operations import RPC, RPCReply
from ncclient import manager

m = manager.connect(
                host='[addrres]',
                port='830',
                username='[username]',
                password='[password]',
                look_for_keys=False,
                allow_agent=False,
                hostkey_verify=False)
                
class RPC(RPC):
    def _wrap(self, subele):
        return subele

class REPLY_CLS(RPCReply):
    def parse(self):
        self._parsed = True
        return True

RPC.REPLY_CLS = REPLY_CLS
rpc = RPC(m._session, m._device_handler)


pl=pl.replace("101",rpc._id,1)

reply=rpc._request(pl)

print(reply.xml)
