#ONTAP Simulator 9.14 : ifgroup not working under VMWare Workstation Pro 17.5.2

Hi,

Have any of you found out a way to make ifgroups working under vmware workstation pro ?
Whenever I attempt to map my cluster management lif to an ifgroup interface, I loose connectivity to my cluster.

I've attempted to follow some support answers on the website but answers seems to be more for ESXi or any other hypervisors.

what type of ifgroup? single or multimode?

#

Single mode should work.Multimode_lacp will 100% NOT work as it requires switch setup to work

#

I would think SINGLE mode and multimode might work but not with vlans. Only as access

gusty bane
#

apparently this is due to e1000 not accepting any traffic from an unidentified mac address

#

(the one generated by the ifgroup)

#

I couldn't find a working solution rn, sadly I wanted to learn abit more with ifgroups

elder musk
#

You may be able to tell esxi to modify the interface security to accept MAC. It may be defaulted to reject

gusty bane
#

I couldn't find an option to allow promiscious mode

elder musk
#

I’ll see if I can check later

thanks !

yeah you need to enable promiscuous mode. I thought this was in the docs to the simulator? But maybe only for ESXi.
For Workstation you have to edit the VMX file manually. The option is called ethernet0.noPromisc = "FALSE"

@small oasis does not seem to work, I create an ifgrp including e0c & e0d, both interfaces has the cmd above in the VMX file. the a0a ifgrp is then added in the Default broadcast-domain, I then tried to set the home-port of the cluster_mgmt lif to a0a

mmhm... you could try to connect the ports to another VM runnig a Cisco Nexus NX-OS switch simulator (Nexus 9000v or something similar) that supports LACP...this will be a complicated setup though so you're on your own there

Thanks still for the help !

#

@small oasis apparently there's a way to make the simuator work with virtualbox (and hope they make a doc about this, vmware kinda sucks since broadcom bought them)

#

will try

Found a guy on reddit who shared the official binary

#

When it's free, you're the product

I wonder if the ONTAP firewall may be a problem? Why would you map it to an ifgrp?

gusty bane
#

Just for redundancy and learning purpose

uncut bison
#

Ah. Honestly redundancy isn't really needed becuase the LIF fails over automatically, but if it's down more than likely other things are down too. LIF failover makes more sense if you have HA or physical NICs for the Cluster Management LIF.

Well that was my usecase on my simulator but I know this is used to aggregate links, sharing load etc..

#

Thanks for your answer !
