Best way would be through the Schema/Template definition on MSO.  There you can see the logical configuration and confirm if and to which sites an EPG is stretched.  There are some backend ways like looking at translation tables on the spines, but MSO would be the best bet if you're new to ACI.

You can do the following from APIC CLI:

1. Get all the extended EPGs:

apic1# fabric Spine210 show dcimgr repo sclass-maps
 
----------------------------------------------------------
     Remote            |        Local
site  Vrf       PcTag  |  Vrf      PcTag     Rel-state
----------------------------------------------------------
  6   2326528   32770  |  2195456   49154   [formed]
  6   2326528   16386  |  2195456   16388   [formed]

 

 2. Convert them to "human readable data":

apic1# moquery -c fvAEPg -f 'fv.AEPg.pcTag=="16388"' | grep name
name : EPG_VLAN100
nameAlias :

 

You can also do it the other way around.

 

1. Get the EPG you are interested in:

apic1# moquery -c fvAEPg -f 'fv.AEPg.name=="EPG_VLAN100"' | grep pcTag
pcTag                : 16388

2. Lookup the Spine translation table:

apic1# fabric Spine210 show dcimgr repo sclass-maps | grep 16388

 

Hope it helps!
