Hi folks,
I 've trying to solve a problem on our integration betwen ACI with VMM domain(version 5.5) and Vmware enviroment(ESXi 5.5). Some VM's lost conectivity after reboot and sometimes without no reason. To deal with it, I need to change the virtual machine's port group to another one and apply the configuration. Then it is changed back to the original port group, all using VMWare Web Client. This is just a workaround and ocasionaly the issue happens again with the same VM and others. Anyone got the same problem?
Note: We have a Vmm domain on version 6.5 working without problems

How's MAC pinning configured ? are VMs pinned to one FI or both ? Do you have any faults related to MAC flapping from interface to interface ?

Hi,
MAC pinning is configured on both VMM domains.
I got some events of detached and attached, is this a MAC flapping event?

Some questions:
Looks like there's a vPC policy group configured on ACI, but you have MAC Pinning enable on the vSwitch. Is there an intermediate switch/blade_switch to require this configuration?

Hi Robert,
The MAC Pinning is enabled on vSwitch, i got a table mapping ACI and Vmware terms.
I confirmed on Vmware enviroment the port group configuration.
But, there is a diference betwen VPC interface policy group and VMM domain port channel policy configuration .
On VMM domain the port channel policy is Mac Pinning, on VPC interface policy group the Port Channel policy is LACP-ON, is it a problem?
I'm still checking the IBM Blade switch for the intermediate configuration.
Regards,
Ricardo

Ricardo, you also have CDP disabled on uplink vPC. Is DVS configured with CDP or LLDP ?
