Gmuloche hello,
Sorry for being late to conclude this.. I did some more reading and testing..
I am using nso-5.3.3.. i agree, behaviour would be same with at least other nso-5.x versions.
a small clarification :
gmuloche: In your scenario above there is something quite not clear to me yet - once you have modified the service on the lower-node-1, your upper node should now see lower-node-1 as Out of sync like:
erdem: when "devices global-settings out-of-commit-behaviour" is set to accept, then NSO doesn't show OOS while re-deploy ing the service. Default value is reject, and in example 22 default value is used. So, service can be re-deployed from upper-nso to lower-nso. I used accept in my testing at that time.
Solution :
As you suggested sync-from lower-nso-1 from upper-nso solves the problem and re-deploying service from upper-nso to lower-nso is then possible.
Actually, as far as i understand, before doing any re-deploy from upper-nso, sync-from lower-nso from upper-nso would be the way-forward . Below is a fun-fact related to this.
fun-fact : ( set "out-of-commit-behaviour = accept" ) ( based on example-22 )
> When we change vlan-id(vid) from 77 to 78 by help of vlan-service on lower-nso-1, "cfs-vlan v1 re-deploy dry-run" dosn't show any diff.
> but, when we change vlan-id(vid) from 77 to 78 by help of device-manager on lower-nso-1, "cfs-vlan v1 re-deploy dry-run" shows the diff.
> note: after sync-from lower-nso-1 from upper-nso, the diff is shown in either cases.
reason for this is that ( as far as i interpret it), nso assumes sync conditions between upper-nso and lower-nso, and hence while doing "cfs-vlan v1 re-deploy dry-run" from upper-nso, upper-nso sends netconf edit-config message only with vlan=v1 (see below netconf message extract) and tries to see if there is a change in device-manager level in lower-nso by "by help of a dry-run transaction"... And s there is no difference between (vlan v1) service and device-manager, no diff is sent back.. On the other hand, when we change vid-78 from device-manager level,the diff is sent back.:
(only relevant parts included for simplicity..)
<hello xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
<start-transaction>
<edit-config><config><vlan><name>v1</name></vlan></config></edit-config>
<prepare-transaction><dry-run><outformat>cli</outformat>
<rpc-reply><dry-run-result><cli></cli></dry-run-result></rpc-reply> <-- see, there is no diff
<abort-transaction>
<close-session/>
Also see, when there is change in lower-nso-1 by help of vlan service, and we sync-from lower-nso-1 from upper-nso, while doing "cfs-vlan v1 re-deploy dry-run", upper nso sends the modified parameter as part of edit-config message :
<edit-config><config>
<vlan><name>v1</name><vid>77</vid></vlan></config></edit-config>
screen outputs :
case-1 : modifying vlan service on lower-nso-1 by help of vlan-service..
- change the service in lower-nso-1 with "vlan v1 vid 78"
- re-deploy dry-run from upper-nso
admin@upper-nso(config)# cfs-vlan v1 re-deploy dry-run
cli { <-- diff is not shown
}
- re-deploy dry-run from upper-nso, after sync-from lower-nso-1 from upper-nso
admin@upper-nso(config)# devices device lower-nso-1 sync-from
result true
admin@upper-nso(config)# cfs-vlan v1 re-deploy dry-run
cli {
local-node {
data devices {
device lower-nso-1 {
config {
vlan v1 {
- vid 78;
+ vid 77;
}
}
}
}
}
lsa-node {
name lower-nso-1
data devices {
device ex0 {
config {
sys {
interfaces {
interface eth3 {
unit 3 {
- vlan-id 78;
+ vlan-id 77;
}
}
}
}
}
}
}
vlan v1 {
- vid 78;
+ vid 77;
}
}
}
case-2 : modifying vlan service on lower-nso-1 by help of device-manager..
- change the service on lower-nso-1 by help of "devices device ex0 config sys interfaces interface eth3 unit 3 vlan-id 78"
- re-deploy dry-run from upper-nso
admin@upper-nso(config)# cfs-vlan v1 re-deploy dry-run
cli {
lsa-node {
name lower-nso-1
data devices {
device ex0 {
config {
sys {
interfaces {
interface eth3 {
unit 3 {
- vlan-id 78;
+ vlan-id 77;
}
}
}
}
}
}
}
}
}
- re-deploy dry-run from upper-nso after sync-from lower-nso-1 from upper-nso
admin@upper-nso(config)# cfs-vlan v1 re-deploy dry-run
cli {
lsa-node {
name lower-nso-1
data devices {
device ex0 {
config {
sys {
interfaces {
interface eth3 {
unit 3 {
- vlan-id 78;
+ vlan-id 77;
}
}
}
}
}
}
}
}
}
Thanks and regards gmuloche.
