Hello,
I have configured mac-pinning. How can I see in Nexus which VEthernet interface is pinned to which Ethernet-NIC ? I didn't find it.
This is our used nx-version: 4.0(4)SV1(3)
Thanks
Hendrik

To show the pinning you need to query the VEM module. You can do this directly on the ESX host via vemcmd on the command line or you can remotely query the VEM from the VSM.
From the VSM run the following command.
n1000v-MV# module vem 5 execute vemcmd show port

Find your vmnic interfaces.and in the output and cross reference with the SG_ID column. Here you can see that vmnic1 is SGID 1 and vmnic2 is SGID 2
Next find the line with your VM and cross reference with the Pinned_SGID column. The number in that column will be either 1 or 2. If it's 1 then the VM is pinned to vmnic1 and 2 would mean vmnic2

hello,
after more then one hour I stop searching for a solution on nexus. So if you configure pinning manually, the assignments are readable in the config. If you choose automatic assignment by cdp, have a look at the mac-address-table interface x/y on the connected physical switch. There you can find the mac address from all vm`s which use this uplink.
