Hello,
we use nso-5.3 in a local installation.
We have this part in a yang file:
container mvr {
description
"mvr";
leaf status {
type cml_data_types:CML_ENABLE_DISABLE_T;
default "disable";
description "Use this attribute to enable/disable MVR.";
} // END of status definition.
list mvrVlan {
when "../status = 'enable'";
key "vlanId";
description
"mvrVlan";
leaf vlanId {
type cml_data_types:CML_INT32_T {
range "1..4094";
}
description "Specify the VlanId for MVR";
} // END of vlanId definition.
leaf-list groupAddr {
type cml_data_types:CML_IPV4_ADDR_T;
description "Specify Group IP address for VlanId to be added to MVR.";
} // END of groupAddr definition.
} // End of mvrVlan-list
} // END of mvr-container definition.
In case of a "delete" operation we receive this RPC from NSO:
<mvr xmlns="http://....">
<mvrVlan xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0"
nc:operation="delete">
<vlanId>240</vlanId>
</mvrVlan>
<status xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0"
nc:operation="delete"/>
</mvr>
This causes some problems because as a first operation on the server
"status" gets deleted, so it falls back to default which is "disable"
and then the “mvrVlan” gets deleted internally and is no longer valid.
A subsequent try to access and delete leaf vlanId results in an error.
Why does NSO send a delete for "status" and the depending "mvrVlan"?
In my understanding a delete for "status" would be sufficient.
(note: We checked that NSO obey the “when” condition, e.g. it is not possible
to create “mvrVlan/vlanId” if "status" is in default.)
Is there a way to tell NSO to send delete for "status" only?
I'd be very happy for any hint!
