Is there a MO for Host and Host PG similar to DV-PG?

Hello, I wanted to get the attributes of the Distributed -PG (DPG) and a regular Host PG. For a DPG, i cache the Managed Object (MO) of the top-level Distributed Switch and each of its (DPG). Something like this:

    container = self.si_obj.content.viewManager.CreateContainerView(
        si_obj.content.rootFolder, [vim.DistributedVirtualSwitch],
        True)
    for dvs_obj in container.view: **// Gives the DVS object**
        dvs_pgs = dvs_obj.portgroup 
        for dvpg in dvs_pgs: **// Each dvps refers to the DV-PG’s objects in the DVS**
            pg_dict.update({dvpg.name: dvpg})

I am using the cached objects above to get the attributes like VLAN, vnic and other network attributes. Even, when the network attributes are updated in vSphere, i am able to get the latest values when i re-read the object’s attributes.

But, for host PG, i don’t see a similar MO. When, i do something like below:

    container = self.si_obj.content.viewManager.CreateContainerView(
        self.si_obj.content.rootFolder, [vim.HostSystem],
        True)
    for host_obj in container.view:
        host_pgs = host_obj.config.network.portgroup
        for hostpg in host_pgs: **// host PG is not a MO**
            pg_dict.update({hostpg.spec.name: hostpg})

‘hostpg’ above seems to be a big structure, which will not get updated dynamically when any of the PG parameters in a host changes. Accessing each attribute seems to be really slow. Is there a MO for a host PG as well similar to DV-PG? Am i missing something?

Thanks, KP
