Ansible Netping

[Netmart]

Hello, 

I am trying to run a simple Ansible net_ping task, but for some reason it is not able to execute the command on switch:

It is probably something obvious I overlooked.

Though running the same command string in prompt mode directly on the switch, it is accepting it:

#ping ip 172.26.219.11 repeat 20 source 172.26.219.1
Type escape sequence to abort.
Sending 20, 100-byte ICMP Echos to 172.26.219.11, timeout is 2 seconds:
Packet sent with a source address of 172.26.219.1
!!!!!!!!!!!!!!!!!!!!

@Netmart hi, i am not sure why this getting ip domain lookup. you can try 'no ip domain-lookup' before run the script. in the same script check if any special characters included in command. you can copy paste exact command from the cli. those are few suggestions from my side to tshoot.

Couple of idea, use the https://docs.ansible.com/ansible/latest/collections/cisco/ios/ios_ping_module.html instead, from what i read, ansible.netcommon.net_ping is a generic module, and this why the syntax is broken (see your error marker). If you want to use this module, you would have to work around the that the module thinks 'ip' is a hostname, which is being added/inserted by net_ping module. Looking at the doc https://docs.ansible.com/ansible/2.9_ja/modules/net_ping_module.html - maybe? Not used Ansible in years.. so check this please!
