    As far as I understand available TCP/IP stacks in vSphere v8.x
    ⦁ Default TCP/IP stack : manage host-related traffic services. This stack shares single default gateway between all configured network services. starting v6
    ⦁ vMotion TCP/IP stack: Isolate vMotion traffic onto its own stack. This stack completely removes vMotion traffic from the default TCP/IP stack. starting v7
    ⦁ Provisioning TCP/IP stack: Isolate some VM-related operations such as migrations, cloning , snapshots or NFC traffic . starting v7
    ⦁ mirror TCP/IP : starting v8: specifically for all replication operations

    ⦁ ops TCP/IP: starting v8 : But what is the use of this stack?

    The link above doesn't appear to reference the new "ops" TCP/IP stack, but the link below does:

    https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-networking/GUID-55FCEC92-74B9-4E5F-ACC0-4EA1C36F397A.html

     

    Note the section:

    "To configure IPFIX on a vSphere Distributed Switch backed by ESXi on DPU, you must create vmknic on ops TCP/IP stack. Else, the flow information is not exported to collector."

    Looks like the "mirror" stack is used in ERSPAN port mirroring, not replication. From what I can tell it's been a round since vSphere 7, but only added to the docs in vSphere 8.  Is there anyone still using vSphere 7 that can double-check that mirroring is an option?

    Create a Port Mirroring Session (vmware.com)

    Thanks,

    Hello jicooper,


    No, I don't think it's so, the "OPS" TCP/IP stack was absent till the first build of ESXi 8.0, I can tell you that ESXi 7.0U3n it does not feature any "OPS" TCP/IP stack, the same way as previous versions of which I still have memory.

    Relative to OPS, that makes sense.  After all, DPU support wasn't introduced until vSphere 8.  What about the mirror stack?  Do you see that in vSphere 7?

     

    Thanks,

    Hello,


    Sorry, in ESXi 7.x there are three types of TCP/IP stack, the "default" one, the "vMotion" one and the "Provisioning" one, nothing else.
