Hi all,
we are developing an cfs and rfs service for use on a LSA NSO setup. On the cfs service and the upper LSA node I want configure a leaf, which has a leafref to devices/device of the lower LSA Node.
Like this:
leaf vmanage {
tailf:info "the vmanage used for this customer";
type leafref {
path "/ncs:devices/ncs:device[ncs:name=current()/../../../rfs-node]/ncs:config/ncs:devices/ncs:device/ncs:name"
}
}
we import the tailf-ncs module with the ncs prefix:
import tailf-ncs {
prefix ncs;
}
When I try to compile this yang it does not work, because it can not find the second ncs:devices node from the lower-node:
../../cfs-sdwan-cisco/src/yang/csc-sm-customer-central-rfs-settings.yang:30: error: the node 'devices' from module 'tailf-ncs' (in node 'config' from 'tailf-ncs') is not found
the path works until "/ncs:devices/ncs:device[ncs:name=current()/../../../rfs-node]/ncs:config". the question is: why does it not find the "ncs:devices" node behind "ncs:config" of the lower-node?
Interestingly, if I do a "show | display xpath" on the nso cli of the upper-node it shows the path to the lower-node like this:
[edit devices device rfs_sdwan config ncs:devices device]
cloud@ncs% show | display xpath
/devices/device[name='rfs_sdwan']/config/ncs:devices/device
I guess there is some problem regarding the ncs prefix and the duplicated "devices/device" nodes, but i can not figure out how to address this correctly in the xpath of the leafref in the yang.
Edit:
I also tried a deref like this:
path "deref(../../../rfs-node)/../ncs:config/ncs:devices/ncs:device/ncs:name";
With the same result.
../../cfs-sdwan-cisco/src/yang/csc-sm-customer-central-rfs-settings.yang:31: error: the node 'devices' from module 'tailf-ncs' (in node 'config' from 'tailf-ncs') is not found
make: *** [Makefile:27: ../load-dir/cfs-sdwan-cisco.fxs] Error 1
By the way, the NSO Version is this:
cloud@ncs> show ncs-state version
ncs-state version 6.1.2.1
