SDK and Documentation

bull Available on DevNetndash httpsdeveloperciscocomsiteapic-dcndash Downloads -gt Python Egg Files

bull Can be downloaded from APIC atndash httpsltapicgtcobrandash Remember to rename the eggrsquos before

installing

bull You will need to reference the Management Information Model Bookmark it

ndash httpsdeveloperciscocommediamim-ref or httpsltapicgtdochtml

bull Python SDK docs (and install directions)

ndash httpsdeveloperciscocomsiteapic-dcdocumentspythonapi or

ndash httpsltapicgtcobra

bull APIC REST API User Guide

ndash httpwwwciscocomcenustddocsswitchesdatacenteraciapicsw1-xapirestb_APIC_RESTful_API_User_Guidehtml

21

httpcsco9006xDw6 Python SDK docs and eggs are included on the APIC in 10(2) code but theres a catch


Establish authenticated session

REST

bull Login with username and password in payload

POST apimoaaaLoginxml

ltaaaUser name=admin pwd=insiemegt

bull Response headers include Cookie ldquoAPIC-cookierdquo

ndash Store this and use it for future requests

Cobra

import cobramitaccess

import cobramitsession

ls = cobramitsessionLoginSession(

httpsapic admin insieme)

md = cobramitaccessMoDirectory(ls)

mdlogin()

bull md now contains an authenticated APIC session

bull

22


Simple Queries

REST

bull Query for all client endpoint objects

GET apiclassfvCEpxml

ltxmlgtltimdatagtltfvCEp dn=unitn-

Ciscoap-Blogepg-MySQLcep-

00505682D2FE encap=vlan-501

id=0 ip=0000 lcC=vmm

lcOwn=local mac=00505682D2FE

mcastAddr=not-applicable

name=00505682D2FErdquo

uid=0gtltimdatagt

bull Parse XML results and process as needed

Cobra

bull Use the ldquolookupByClassrdquo method to find all endpoints (fvCEp)

endpoints = mdlookupByClass(fvCEp)

print([str(epdn) for ep in endpoints])

[unitn-Ciscoap-Blogepg-MySQLcep-

00505682D2FE unitn-Ciscoap-

Blogepg-MySQLcep-00505682C3D0]

23

Tip To inspect http requests use debuglevel on httplib

import httplib

httplibHTTPConnectiondebuglevel =

1


Query Filters in Cobra

bull Built in helpers lookupByClass and lookupByDn use query under the covers

bull For advanced queries you can use query directly

bull In this example we recursively print a full subtree for all endpoints

24

def printtree(mos indent=0)

for mo in mos

print indent str(mometaclassName)

printtree(mochildren indent=indent+2)

cq = cobramitaccessClassQuery(fvCEp)

cqsubtree = full

endpoints = mdquery(cq)

printtree(endpoints)

gtgtgt printtree(endpoints)

cobramodelfvCEp

cobramodelfvRsNic

cobramodelfvRsVm

cobramodelfvRsCEpToPathEp

cobramodelfvRsHyper

cobramodelfvReportingNode


Query Filters

bull Usually more efficient as less number of MOs need to be serialized and returned

bull Filter the response returned using the supplied condition(s)

ndash Syntax httpURIcondition[ampcondition[amp]]

bull Returns only the MOs that satisfies the condition(s)

Filter type Syntax Cobra Query Property Description

query-target self | children | subtree AbstractQueryqueryTarget Define the scope of query

target-subtree-class ltclass namegt AbstractQueryclassFilter Respond only elements including specified class

query-target-filter ltfilter expressionsgt AbstractQuerypropFilter Respond only elements matching conditions

rsp-subtree no | children | full AbstractQuerysubtree specifies child object level included in the response

rsp-subtree-class ltclass namegt AbstractQuerysubtreeClassFilter Respond only specified classes

rsp-subtree-filter ltfilter expressionsgt AbstractQuerysubtreePropFilter (gt102m) Respond only classes matching conditions

rsp-subtree-include faults | health stats hellip AbstractQuerysubtreeInclude Request additional objects

order-by ltclassnamepropertygt| asc | desc NotImplemented Sort the response based on the property values

25


Committing Configuration Changes

REST

bull Create a new tenant belonging to policy universe

POST apimounixml

ltfvTenant name=Ciscogt

Cobra

bull Build your objects and commit them

26

Tip To get the configured XML body for the object youve createdmodified add the rsp-include query parameter

POST apimounixmlrsp-subtree=modified

topMo = cobramodelpolUni()

fvTenant = cobramodelfvTenant(topMo name=Cisco)

c = cobramitrequestConfigRequest()

caddMo(fvTenant)

mdcommit(c)

Sample Get fabric OSPF neighbors

bull Typical operations task is to check neighbors

bull Want to have the same look and feel

bull Take advantage of single fabric API to get details from entire fabric

bull Solution Query fabric for all OSPF neighbors and output status in IOSNX-OS fashion


Get fabric OSPF neighbors Code

29

def showOspf(md)

cq = cobramitrequestClassQuery(ospfAdjEp)

cqsubtreeInclude = faults

return mdquery(cq)

neis = showOspf(md)

fields = [(Neighbor ID id) (Pri prio) (State

operSt) (Address peerIp) (Node dn)]

for field in fields

print ltwidthformat(field[0] width=len(field[0]))

for ne in neis

for f in fields

print ltwidthformat(getattr(ne f[1]) width=len(f[0]))

for fault in nechildren

print Fault Present faultdescr

Fetch Neighbors

Print


Get fabric OSPF neighbors Results

bull Proper IOSNX-OS style results with fault detailsNeighbor ID Pri State Address Node

2221 1 exstart 1111 topologypod-1node-103

Fault Present OSPF adjacency is not full current state Exstart

2226 1 full 1116 topologypod-1node-103

Best Practices


Best Practices

1 Utilize built in naming and Dn methods

2 Be granularspecific with your commits and queries

3 Avoid hard coding Dnrsquos that contain naming properties

4 Avoid multiple lookups by starting off with static Dnrsquos instead of resolving

5 Build sparse trees and leverage default values

6 Donrsquot use lsquofromrsquo in imports to avoid namespace collisions

7 Use REST API filtering to reduce result set

32


1 Built in naming and Dn methods

bull When making references between Managed Objects do not manually build Dn strings

bull Instead lookup the object and use the dn property

33

fvRsPathAtt =

cobramodelfvRsPathAtt(fvAEPg

encap=vlan-2 tDn=topologypod-

1paths-101pathep-[eth11])

fvRsPathAtt =


tDn=interfacedn)


2 Commit and Query Granularity

bull The API uses a directory based architecture

ndash Closer to your target means less time and more accurate queries

bull Following this practice also helps avoid context root issues

ndash APIC stores data in distributed data stores

ndash If you go up too high no single APIC can own the data

34



35

bull Want to add a new end point group

Do thiscaddMo(fvAEPg)

Dont do thistopMo = cobramodelpolUni()

fvTenant = cobramodelfvTenant(topMo

name=Cisco)

fvAp = cobramodelfvAp(fvTenant NewApp)

fvAEPg = cobramodelfvAEPg(fvAp NewEpg)


caddMo(topMo)

mdcommit(c)

Tip This technique will not work if the parent Mo does not exist

Eg if the Tenant and App Profile do not exist you cannot add an EPG


3 Avoid hard coded Distinguished Names

bull Naming might change in an environment

bull Avoid re-writing code and bugs

ndash by doing lookups when applicable

ndash Referencing classes instead of instances

bull Note Most important classes have static Dns so you can use the static definition method shown here

36

Dont do thistopDn = cobramitnamingDnfromString(uniinfra)

lacpLagPol = cobramodellacpLagPol(topDn

name=active ctrl=graceful-convsusp-

individualfast-sel-hot-stdby mode=active)

Do thistopMo = cobramodelpolUni()

infraMo = cobramodelinfraInfra(topMo )

lacpLagPol = cobramodellacpLagPol(infraMo




4 Avoid lookups when you can

bull Issuing a remote query will always be slower than defining locally

bull As shown in the last example you can build static Mos for many context roots

bull Avoid two REST queries by building your object locally

37

Dont do thistopMo = mdlookupByClass(polUni)


lookupByClass and lookupByDn both call query() and incur a lookup penalty

Built in local memory and available for immediate usage


5 Build sparse trees and use defaults

bull The REST API is smart and populates defaults as needed

bull Many values read back from the APIC are configuration defaults (eg monitoring policies)

bull Passing all these defaults will add bloat to your code and slow down API calls

38


6 Dont import and avoid from in imports

bull Basic Python practice

bull Name space collisions are annoying

bull The Object Model contains ~5k objects there are object name collisions

bull Avoid them by using namespaces

bull Or use from hellip import hellip as hellip

39

Dont do thisfrom cobramodelactrl import Inst

from cobramodelaction import Inst

a = Inst() We clobbered actrlInst

Do thisimport cobramodelactrl

import cobramodelaction

a = cobramodelactrlInst()

Or this

from cobramodelactrl import Inst as

ActrlInst


7 Server side filtering

bull Its possible to perform multiple lookups process results and repeat for complex searches

bull The powerful filtering on the REST API allows concise queries

40

Get Mo for interface eth11 on node 101cq = cobramitrequestClassQuery(fabricPathEpCont)

cqpropFilter = eq(fabricPathEpContnodeId 101)

cqsubtree = children

cqsubtreeClassFilter = fabricPathEp

interface = [i for i in mdquery(cq)[0]children if iname == eth11][0]

print interfacedn

topologypod-1paths-101pathep-[eth11]

Tip Cobra gt102m supports subtreePropFilterattribute allowing this loop to be avoided
