Trunk between NetGear XS728T and ESXi

Hi everyone,

 

I'm trying to establish a connection between a VM to a physical router.  I want to validate that I've configured everything correctly on my NetGear XS728T ProSAFE 28-Port switch to facilitate this connection.

 

On a high level, this is the flow of data

VM > Port Group on VLAN 50 > vDswitch > NetGear router > Physical router

 

My VM is on VLAN50.  

On the NetGear switch, I've configured the switch ports (21-23) that are connected to the VM hosts to be tagged ports assigned to VLAN 50.  

 

Based on what I read, tagged = trunk, untagged = access port.  

The physical router is connected to port 20, untagged.  

 

On the VM, I cannot ping the physical router if the Port Group is on VLAN 50 configured either as an access or trunk.  The only time ping works is if I remove the VLAN configuration entirely from the Port Group.  I THINK I configured everything correctly on the Netgear side of things but I hope someone here can confirm.  I've done a lot of reading but I've yet to find a description of how to trunk between ESXI/Vcenter and a Netgear switch. 

 

Thank you for your help.

    Hello CtrlClick​ 

     

    And welcome to the NETGEAR Community!

     

    A very vague question, difficult if not impossible to answer. 

     

    Ping from which IP subnet to what other host on the  subnet? 

     

    Is the intention to operate your primary router handling the routing between the different VLAN and so the different IP subnets?

     

    What is on Port 22?

     

    Is there a host operating Tagged for the VLAN 50 you try to reach from your ESXi/vCenter system?

     

    What is handling the routing and DHCP for the IP subnet on that VLAN 50? The existing router or the XS728T IPv4 VLAN routing capability?

     

    Start with providing a basic design document for what you like to implement, with VLANs, IP subnets, ..., like this generic example (which can be right or wrong):
