Hi Syedumairali,

did you resolve this issue?  I have the same issue

Has anyone determined a solution for this?

Hi, were you able to get this resolved? Also what version of the simulator are you running? I see this on 5.0 and Im tempted to download 4.2

Having the same issue. Downloaded and installed 5.1-1h.  I go through and accept all defaults except for the management interface. I specify an IP on the network and correct default gateway.  While other VMs on the same network work, I cannot ping the mgmt IP specified in the simulator setup. 

When going into the APIC for my physical ACI environment, I see the MAC addresses assigned in VMWare to the simulator VM.  Basically this is telling me the simulator is NOT communicating with anything outside the simulator.

Hi @dmcquestion,

Ae you enabling Promiscuous Mode on the VMware vSwitch to which the ACI simulator is connected? (NOTE: if this is a production environment, make sure you understand the impact of this setting before modifying it).

Have a look at Step 2 under "Installing ACI Simulator Virtual Machine" in this doc: https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/3-x/simulator/install_vm/b_Cisco_ACI_Simulator_VM_Install_Guide.html

In my VMware vCenter lab, I have the ACI Simulator's Network adapter 1 assigned to VM Network port group part of Standard Switch: vSwitch0. If in the Standard Switch settings I set Promiscuous mode to Reject, I lose access to my ACI Simulator (I lose access to ACI Simulator APIC's GUI and a ping from my laptop to ACI Simulator's mgmt IP breaks) as soon as I set Promiscuous mode to Accept (screenshot attached), I can again communicate with my ACI Simulator.

One more thing, a ping performed from the ACI simulator's CLI seems to be prohibited but you can do a traceroute after entering bash mode.

apic1# bash
admin@apic1:~> traceroute 8.8.8.8
traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 60 byte packets

I hope this helps.

Regards.

Thank you for the reply!  I compared your screen shot to what I had configured (see screen shot).  I set Promiscuous mode to Accept but I did NOT set MAC Address Changes and Forged Transmits to Accept.  When I set those to Accept, I was able to ping the simulator.  I am pretty literal so I only changed the Promiscuous Mode as called out in the documentation.  Mentioning the other two settings in the documentation or adding a screen shot of the settings in the documentation couldn't hurt.  🙂

If you have not already done so, check your vSwitch in VMware and set MAC Address Changes and Forged Transmits to Accept.

Thanks @Hector Gustavo Serrano Gutierrez 
This really helped me and I was able to get the GUI of my APIC first time ever.

In EXSI, I succeeded by changing the port-group of network to Promiscuous mode as it is shown in pic.
