Help.

I am receiving a seemingly odd error when trying to assign multiple non-contiguous VLANs using the cisco ios\_config module (latest). Below is the playbook.

It runs just fine if there is only one vlan listed, or if there is a range listed (both with a space between them and a hyphen). But the moment Ansible sees that first comma, the job blows up.

Well, I figured out how to have commas in the config command. Rather than having the ‘lines:’ variable being a string, have it be a list with the first entry being the config command:

- name: Issue out dhcp snooping config info  
cisco.ios.ios\_config:  
lines:
- ip dhcp snooping vlan 666,684,784  
register: commandOutput

But this still does not explain why I could issue the one vlan or range of vlans as a single line…
