I am trying to get the lldp neighbours on an interface.

Initially I tried to do this:
lldp_neighbours = apic.methods.ResolveClass('lldpIf').GET(**options.filter(filters.Eq('lldpIf.portDesc',path.tDn)) & options.subtreeClass('lldpAdjEp') )
But this does not work and I am not getting anything back no lldpIf nor lldpAdjEp.

As a work around I did:

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

This works fine and I can then just access the ldp_neighbour.lldpAdjEp instance but can't understand why the first option does not work. In this case is not a big issue as there aren't that many child of lldpIf but I would like to understand how you should this be done.

Looking to get information about how to perform these queries with Pyaci. There are some information in the article below at the end of the page titled "Viewing ACL Permit and Deny Logs Using the REST API"
Here

When running something like this:

result = apic.mit.polUni().fvTenant('Enterprise').GET(**options.subtreeClass('acllogPermitL3Pkt'))
I get an empty list.
To perform the same thing in Cobra ACI would be:
result = self.cobramd.lookupByClass('acllogPermitL3Pkt')

How would i perform this action in Pyaci?

Also how would i pass in an and filters?

Something like this:
result = apic.mit.GET(**options.subtreeClass('acllogPermitL3Pkt') & options.filter(filters.Wcard('acllogDropL3Pkt.dn', f"ndbgs/acllog/tn-{tenant}" filters.Wcard('acllogDropL3Pkt.destination') & filters.Wcard('acllogDropL3Pkt.srcIp','10.71.0.164')))

Hello,

scripts/metagen.py:

"from insieme.pymit.pyaccess import PyClassDirectory"

Is this something Cisco-internal? I can't find that package anywhere. Is it possible to add it to the repo?

Sebastian

I may be missing something obvious in how to import this module, but it seems like it is designed to only work from the command line. I would like to import it into my application to automate the generation of the meta. Something like this:

from Scripts import rmetagen

# If an existing session wasn't supplied, make a new session
if not isinstance(apic, Node): 
    try: 
        apic = Node(config['ACI APIC']['url'])
    except MetaError:
        # This implies that the meta hasn't been downloaded yet
        rmetagen.generateMeta(host, username, password)

APIC responds with an API link to check the post status as PD needs more time to validate

pol.POST()
File "/python3.6/site-packages/pyaci/core.py", line 92, in POST
'POST', format=format, needData=True, **kwargs)
File "//python3.6/site-packages/pyaci/core.py", line 154, in _performRequest
raise RestError(response.text)
Request in progress, please check state using URL: /api/checkRequestState.xml?id=9570149234507776

PyACI doesn't distribute ACI model metadata. It instead comes with a minimal metadata for it's unit tests. User must generate full metadata by connecting to a running APIC of desired version. This is not very obvious as per some users' feedback. When PyACI is started with the minimal metadata, provide hint on how to generate the full metadata.

The following traceback is seen if the .aci-meta directory does not exist. It would be nice if it was automatically created instead.

APIC sessions do timeout. The timeout is indicated in the response to the login request. Track the timeout, and issue auto refresh at say about 60% of the indicated timeout.

If I do multiple GET requests, one after another, pyaci gives errors as below. If I do either GET request by itself, it works fine. Am I doing something wrong or is this a bug?

Code:

sbm = apic.mit.polUni().fvTenant('sbm')
y = sbm.GET(**options.subtreeClass('fvAEPg'))
x = sbm.GET(**options.subtreeClass('fvSubnet'))

How do i get an object with a direct call, and than add it's childern after?

Should look something like this:

#get a direct epg
epg_request = apic.mit.polUni().fvTenant(tenant_name).fvAp(app_name).fvAEPg(epg_name).GET()[0]
#add the childern of that EPG
epg_request.GET(**options.subtree)

Currently unit tests are failing on Python 3. Most of them seem to be some kind of keys ordering assumption that was made by the test. Consult the last circleci build for more information.

In the current design, there is one version of ACI metadata loaded when the module is imported. All Node instantiations share this global metadata. However, there have been asks from various people the ability to talk to multiple versions of ACI from the same process. This can be supported by still having a global metadata, and providing an option in the Node to override the version.

Hello,

In the file options.py, the inplementation of the method and in the class ApiOptions generates an exception in Python3. The reason for this exception is that dict_items can not be added in Py3. The alternative implementation for this method, which is Python 2 and 3 compliant (tested locally) is provided below:

class ApiOptions(dict):
    def __and__(self, other):
        d = self.copy()
        d.update(other)
        return ApiOptions(d)

Could you please apply this fix to the official code repo?

Thanks,
Sven.

WebSocket subscriptions apparently are valid for only 60 seconds. Provide a mechanism to automatically refresh subscriptions.

I have attempted to use all the solutions provided above for getting packets, and my query is returning an empty list.
result = apic.methods.ResolveClass('acllogPermitL3Pkt').GET() result2 = apic.mit.polUni().fvTenant(tenant).GET(**options.subtreeClass('acllogPermitL3Pkt')) result3 = apic.methods.ResolveClass('acllogPermitL3Pkt').GET(**options.filter( filters.Wcard('acllogDropL3Pkt.dn', f"ndbgs/acllog/tn-{tenant}") & filters.Wcard('acllogDropL3Pkt.srcIp', "10.71.0.164"))) test = apic.mit.polUni().fvTenant(tenant).GET()
