I have the following yang model:
leaf device {
tailf:info "Name of the Device to configure";
type leafref {
path "/ncs:devices/ncs:device/ncs:name";
}
}
leaf test {
type leafref {
path "deref(../device)/../ncs:device-type/ncs:cli/ncs:ned-id";
}
}
container device-model {
when "deref(../device)/../ncs:device-type/ncs:cli/ncs:ned-id = 'cisco-ios'";
tailf:info "Model of the device";
choice device-model {
leaf Catalyst-3560x {
type empty;
}
leaf Catalyst-4510 {
type empty;
}
}
// must "deref(../device)/../ncs:device-type/ncs:cli/ncs:ned-id = 'cisco-ios'" {
// tailf:dependency "/ncs:devices/ncs:device/ncs:device-type/ncs:cli/ncs:ned-id";
// }
}
Using NSO version 4.6 with the CLI, when I set data in the model, selecting a device with a ned-id = 'cisco-nx' the test leaf correctly returns only the value cisco-nx. However, I also incorrectly, or at least not the behaviour I am looking for, see the device-model container. How do I use a deref in a when statement, or must statement(with the correct tailf:dependency) so that I either don't see the device-model container when selecting a non cisco-ios device, or at least throw the correct error on a must. Neither seems to work the way I have defined it above
Is this possible?
Thanks,
Johan
