All I have a program that automates the configuration import from a local configuration backup file into the APIC. However, I have no idea how to check if the import is truly completed so that the next sequential task can be started. Obviously, the ...

Hi I am testing a new fabric running ACI 4.1(2x), and encounter rollback exception. The steps I took in the test was simple:1) Take a snapshot2) Create a dummy tenant3) Rollback the snapshotStep 3 failed. Fault dump is attached.Please help.

Hi experts I have an ACI fabric currently designed based on network-centric mode and needs inter-VRF route leaking. Therefore there is one-one mapping among subnet, EPG and BD, and the subnet is defined under EPG rather than the BD. This design is ...

Hi I am troubleshooting on an issue relating to bringing up an ACI multipod. I have a 'seed' pod (pod1) ready. IPN (an n5k) is up. APIC on pod1 is able to learn DHCP Discover originated from the 1st spine (pod2-sp1) of the remote pod (pod2). APIC G...

I have successfully brought up the first APIC of an ACI fabric. It is running 2.2(1o). I have a pair of N938108TC-EX connected by the APIC, and managed to use lldp to detect them. Example below. Just have no idea why I cannot see this new node dis...

Thanks for the explanation!

Thanks all for the feedback! Hi Jason I am especially interested in the scenario in which both subnets are defined under the BD; both EPGs must provide and consume a contract with each other. May I know how such mutual provider-consumer relatio...

Need your further explanation

Thanks! yes that’s my case. I’ll need two EPGs having the same default gateway so I intend to put the subnet with the gateway IP under their BD in common. You mean I can also add the exactly same subnet (with the same gateway IP) to the one EPG that ...

If putting subnet on BD, how to support inter VRF route leaking that is supposed to be achieved by putting subnet under epg?
