[alankoh]

hi

if a vmnic is use as 1 of the active adapter in a vswitch but there is no vmkernel created in the vswitch - am i still able to see the mac address of the vmnic in the physical switch ?

i am trying to trace the physical connection of the vmnic in the physical switch but i am not able to see any mac address of the vmnic in the physical switch yet i am able to see the mac address of the vnics of the guest vms that use this vmnic uplink in the physical switch

thank you

Hi @alankoh ,

By default, these hosts are only set to listen. To verify, you can run this command against the vswitch: esxcfg-vswitch -b vSwitch0 

Note: Change the vSwitch name accordingly

This can be changed by running following command: esxcfg-vswitch -B both vSwitch0

Available options: "listen", "advertise", "both"

Hope that helps

Hi Krishnan

What is the usage of this command ?  I am not using Cisco physical switch

Does this command force the VMNIC to send its MAC address to the physical switch ?

I see that the VMNIC is physically connected to the physical switch but I am not able to find its mac address in the physical switch

Thank you
