MAAS 2.0 add subnet

When I try to add a subnet on MAAS 2.0 I have the following configuration:

  • VLAN masstest/untagged space masstest
  • CIDR 10.20.0.3/16 name testadmin
  • Gateway IP 10.20.0.2 DNS 10.20.0.3

When I submit it I get "Extra data: line 1 column 6 (char 5)". What is this trying to tell me?

Are you adding an IP or a subnet? If you are adding a subnet you probably want it to be 10.20.0.0/16 since that is the network for the /16 and not 10.20.0.3/16.
