3883.0. "How to find INLINK attribute in MCC ELM" by BSS::AMBER (Mark Amber, CXO3 LAN Mgr. (DTN)592-4645) Thu Oct 08 1992 18:15

I previously used DECelms to poll all the bridges and get back a spanning
characteristic called INLINK.  Using this with a few other attributes makes
it possible to map the LAN.

Now, with MCC elm, I can't seem to find this attribute.  I suspect its there
somewhere, since the LAN Autotopology  must be using it.  Can anyone tell
me how to ask MCCelm to show a bridge's INLINK attribute?

    I can't find an attribute called "INLINK" in the RBMS spec.

    I ran MSU ELMS which I think is essentially the same as DECelms in its
    displays.  There is a line spanning characteristic called "Designated
    Link Number."  Is this what you mean?  If so, the DECmcc equivalent is
    called "Designated Port Number."

    OK, I checked again and found INLINK.  It's a Device attribute.  Its
    MCC name is "Root Port".  It is not used by LAN Autotopology.  Here's
    the description from the Bridge AM spec:

        ATTRIBUTE Root Port = 45 : Unsigned8
                ACCESS = NONSETTABLE,
                DISPLAY = TRUE,
