Where can I find my APIC infrastructure VTEP Pool?

[cowser1979]

I inherited a configured fabric, with 1 controller in the cluster.  I am adding the other 2, and need to know what the preconfigured VTEP pool was set to, when the original controller was set up.

thanks

Hello! 

In 2.0.x, you can find the information under Fabric > Inventory, and each Pod will have an entry under 'POD Fabric Setup Policy',

In earlier versions, you can ssh to the APIC and look at the output of 'acidiag avread'. There will be an entry TEP ADDRESS=. That should give you the current TEP pool allocated. 

Example Output:

apic1# acidiag avread   

Local appliance ID=1 ADDRESS=10.0.0.1 TEP ADDRESS=10.0.0.0/16 CHASSIS_ID=88397774-3ca1-11e6-ad19-6127bd4cf737

Cluster of 1 lm(t):1(zeroTime) appliances (out of targeted 1 lm(t):1(2016-06-30T16:00:29.720+00:00)) with FABRIC_DOMAIN name=ACI Fabric1 set to version=apic-1.3(2h) lm(t):1(2016-06-30T16:00:36.659+00:00); discoveryMode=PERMISSIVE lm(t):0(1970-01-01T00:00:00.001+00:00)

Perfect!

No problem! Actually the acidiag command will work even in 2.0 versions. In 1.x there may be a  way to see the exact VTEP pool used from the GUI, but I am not quite sure where it can be found as it wasn't where I thought (on the Controller details page).

Very useful command.

Thank you
