ACI Solution Overview

ACI and APIC DC

bull Application Centric Infrastructure (ACI) represents network configuration with application based semantics

bull Fabric functions as single switch Scale Mobility Telemetry Automation

bull Cisco APIC is a centralized point of management for physical virtual and cloud infrastructure

bull Robust implementation designed around open standards and open APIs

Unflattening network configuration

bull Network configuration today is based around flat configurations

bull This does not represent the richness of applications and business

bull We need representation as something more flexible

ACI Object Model

bull A modeled representation of everything APIC knows

bull Network Compute Application etc

bull Management Information Tree (MIT) Tree based structure

bull MIT has distinct branches for different functional areas

bull Every node is a managed object

bull has a class amp distinguished name

bull Critical component to working with APIC beyond programmatic interaction

Distinguished Name

bull DN is used as a globally unique identifier for an object in the MIT

bull Formed by getting relative name (RN) and appending it to parent RN until reaching topRoot

bull RN naming rule depends on object

Simple Queries

REST

bull Query for all client endpoint objects

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])

Tip To inspect http requests use debuglevel on httplib

import httplib

httplibHTTPConnectiondebuglevel =

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

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)

bull 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-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

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

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)

Another Tip Disable the annoying Requests Insecure Warning Put this at the top of your script

import requestspackagesurllib3

requestspackagesurllib3disable_warnings()

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 Codedef 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]))

Sample Print all EPGs used on all Leafs

bull Need to perform impact analysis

bull Check which app tiers will be impacted by leaf downtime (code upgrade etc)

bull Quick way to find EPGs used on Leafs

bull REST API provides Trace method to find this

Print all EPGs used on all Leafs Code

ls = cobramitsessionLoginSession(apicUri apicUser apicPassword)


mdlogin()

leaf_nodes = mdlookupByClass(fabricNode propFilter=eq(fabricNoderole leaf)

for leaf_node in leaf_nodes

Best Practices

Best Practices

1 Utilize built in naming and Dn methods

2 Be granularspecific with your commits and queries

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

4 Donrsquot use lsquofromrsquo in imports to avoid namespace collisions

5 Use REST API filtering to reduce result set

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

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

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

bull Following this practice also helps avoid context root issues

bull APIC stores data in distributed data stores

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


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 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

Dont do thistopMo = mdlookupByClass(polUni)

Do thistopMo = cobramodelpolUni()

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

Built in local memory and available for immediate usage

4 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

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

5 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

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


Tip Cobra gt102m supports subtreePropFilterattribute allowing this loop to be avoided

Applicability

How others are using these

bull Partners with application and business modeling

bull Direct translation of business rules to application policy

bull Customers with large repeated deployments

bull Repeated EPG-as-VLAN build outs

bull Template based definitions for new tenant onboarding

bull Within Cisco

bull Fully automated QA solution test process

bull Advanced Services rapid testbed deployment

bull Cisco IT heavily leveraging APIC automation

Conclusion

Conclusion

bull APIC APIs are being used today

bull Cisco APIC provides open API for complete platform access

bull Powerful data manipulation and processing

bull True object oriented interface
