ACI APIC & Node – MOQuery / API Format Examples

A collection of examples for moquery, native REST API calls and other random commands. Little unstructured (sorry), at some point I will move to separate pages.

CLI - show system internal [epm|eltm|ethpm]
epm: Endpoints

MOQuery Queries

Query Filter Types
wcard = * or .
query-target-filter=eq("fvRsPathAtt.encap", "vlan-1971")

User Query (User Delete Action)
moquery -c aaaModLR -f 'aaa.ModLR.user=="XXXXX" and aaa.ModLR.ind=="deletion"' | grep descr

User Query (User Actions on Date)
moquery -c aaaModLR -x 'query-target-filter=wcard(aaaModLR.created,"2016-02-22")' | egrep "user"

Bridge Domain Multicast addresses
moquery -c fvBD | grep 'name|bcastP'

Get Static Paths using mo filter to return full object
moquery -c fvRsPathAtt -f 'fv.RsPathAtt.encap=="vlan-23"'

Get the dn of the path for a switchport & switch
moquery -c fvAPathAtt | grep dn | grep 'eth1/47' | grep 202
moquery -c fvStPathAtt | grep dn | grep 'eth1/47' | grep 202
moquery -c fvDyPathAtt | grep dn | grep 'eth1/47' | grep 202

If the object names are prefixed - i.e. with EPG_
show vlan ext | grep Eth1/47 | grep EPG_

Find the BD an APP uses.
moquery -c fvBD -x rsp-subtree=children query-target=subtree -f 'fv.RtBd.tDn=="uni/tn-TEN_ONE/ap-APP_ONE/epg-EPG-V123"'

Get all subnets of a BD with ip and dn filter
moquery -c fvBD -x rsp-subtree=children query-target=subtree target-subtree-class=fvSubnet,fvRtBd | egrep '^ip|^dn'

Get the endpoint ip, mac, TEN, APP, EPG, VLAN
moquery -c fvCEp -x rsp-subtree=full -f 'fv.CEp.mac=="00:00:5e:01:01:d8"'

I have been in the IT sector for over 20 years with a primary focus on solutions around networking architecture & design in Data Center and WAN. I have held two CCIEs (#20221) for over 12 years with many retired certifications with Cisco and Microsoft. I have worked in demanding and critical sectors such as finance, insurance, health care and government providing solutions for architecture, design and problem analysis. I have been coding for as long as I can remember in C/C++ and Python (for most things nowadays). Locations that I work without additional paperwork (incl. post Brexit) are the UK and the EU including Germany, Netherlands, Spain and Belgium.
