VMM integration and domain selection | F0467

[Daniel S.]

Hello ACI people,

I have over 50 faults "F0467" for Configuration failed.

The problem is clear, encap VLAN not present in the VLAN pool.

There are a few vPCs towards Fabric Interconnects, trunk with VLAN encap 1000.

In the specific EPG, domain added is VMM domain with VLAN range 1500-2000.

Obviously the encap VLAN 1000 is missing.

I am still not sure why customer set it up like this (waiting for answers).

This VLAN 1000 is present in another VLAN pool (Physical domain).

One solution would be to change the encap VLAN, which I can not change right now.

The second option would be to add second Domain (Physical domain) to that EPG, where VLAN 1000 is present.

This would clear the fault.

The question is, would this affect the ongoing traffic?

Thank you in advance!

Could you please take time to explain the above statement of yours. Would appreciate if you could share configuration for the above statement.

I have just tested it in the lab and adding additional domain under the EPG did not cause any interruption to the traffic.

This would be needed anyway if they are planning to insert any physical workload to that EPG, but still waiting for a confirmation about what is the reason to have it like it is.

I just needed to make sure that nothing would flap.

Thank you for the interaction.
