- Installed APIC-EM 22.214.171.124 in LAB environment on VMWare 5.5. The installation has been working fine. After the first reboot realized a connection loss one or two times within 5 minutes for about 30 seconds or sometimes longer. I checked network the network path, but everything looked fine. ARP-Entries, CAM-Entries and so on. During connection loss I realized no high utilization of the VM itself.
- VMXNET NIC for this VM have changed to E1000 and reinstalled the whole Controller. After that still got connection issues.
- Have also installed VMWare Tools for VMXNET.
Installing VMWare Tools finally fixed the problem!! So use E1000 NIC type, install VMWare Tools and you will be happy with APIC-EM on VMWare...
