How to use ResolveClass with subtreeClass about pyaci HOT 3 CLOSED

I'm not sure what exactly you are trying to do. I'm assuming that you are retrieving LLDP adjacencies for a given port (fabric PathEp DN). This is my recommendation on how to do it. (There are many ways of doing this)

[iface] = leaf.methods.ResolveClass('lldpIf').GET(**(
    options.filter(filters.Eq('lldpIf.portDesc', 
                              'topology/pod-3/paths-1017/pathep-[eth1/23]')) & 
    options.rspSubtreeClass('lldpAdjEp')))
for adj in iface.lldpAdjEp:
    print(f'Adjacency {adj.id} => {adj.sysName}:{adj.portDesc}')

Output

Adjacency 1 => ifav11-n3k-5:Ethernet1/15

from pyaci.

These options are passed on to the server using the URL constructed. Please look at the query filters section in this documentation. IIRC, subtreeClass is applicable only when you are using it with rspSubtreeFull or rspSubtreeChildren. Please turn on logging to see the corresponding REST API requests it is making.

logging.basicConfig(level=logging.INFO)

I see, thanks the logging was also very helpful :)

Like this works

lldp_neighbours = apic.methods.ResolveClass('lldpIf').GET(**options.filter(
filters.Eq('lldpIf.portDesc',path.tDn)) & 
options.rspSubtreeChildren & options.subtreeClass('lldpAdjEp,lldpIf'))

Just wondering why I have to add lldpIf in the subtreeClass as I would think lldpIfis the root of the tree? But might be how APIC works.

Regardless thanks a lot !!!

EDIT: Figured the above out, I need to use rspSubtreeClass not subtreeClass
