    Hi Dom,
    
    I don't quite understand the LAN Bridge 100 does not have the Permanent
    DB(Nonvolatile DB).  All LAN bridges and DEC bridges have Permanent DB.
    If you want to filter an address, you have to create it in the
    forwarding database.  The disposition = filter is the default value.
    For example,
    
    MCC> create bridge LANB_100 forward database static entry
    08-00-2b-11-22-33
    
    or
    
    MCC> create bridge LANB_100 forward physical entry 08-00-2b-11-22-33
    
    default disposition will be FILTER.  If you want to change the
    disposition for that entry, you can do it two ways:
    
    1) use "DELETE" to remove it.  That address will be learned and will be
    forwarded
    2) use "SET" command to change the disposition.
    
    Please do not use the "PHYSICAL ENTRY" when you create or set the
    forwarding database entry.  Instead, use the "STATIC ENTRY".  The
    "PHYSICAL ENTRY" will be obsoleted for the next version of Bridge AM.
    
    If you have any question, let me know.

    	Sorry but the STATIC ENTRY doesn't work. I'm using the BMS V1.1,
    and you?

  The Bridge AM that shipped with DECmcc ELM AM V1.0 (which added support
  for DECbridge 500 series and DECbridge 600 series) split the child
  entity PHYSICAL ENTRY into: STATIC ENTRY and DYNAMIC ENTRY.

  Dynamic Entries are those that are LEARNED by the Bridge.

  For THAT version of Bridge AM, PHYSICAL ENTRY was maintained for
  backward compatibility...

  For the Bridge AM shipping with DECmcc ELM AM V1.1 (i.e. the Bridge AM
  that layers on DECmcc V1.2), the PHYSICAL ENTRY child entity will
  completely disappear.

  My guess at what you were TRYING TO ASK (as opposed to what actually
  appeared) is something like this:

    "I have an address on my LAN that I want to filter. I can't SET CHAR
    because it doesn't work. The info I have says to CREATE the entry and
    then it'll be filtered - but the CREATE is rejected since the bridge
    already knows the address (it was heard by the bridge and added to
    its Volatile DB)."

  The best answer I saw for this problem appeared in the RBMS_LANBRIDGE100
  notes conference a few years ago (discussion was framed in the context of
  the Remote Bridge Management Software (RBMS) point product...
  Basically you:

	1. DELETE the learned address, and then (very quickly!)
	2. CREATE the address.

  If I remember correctly, it was suggested that the two commands appear
  in a .COM file so that you had "half a chance" of creating the address
  before it got learned again...

  Jae Park (and company) will have to verify that this is true (one would
  think that the LB100 firmware would have been fixed by now).

  Note that the above workaround will NOT work once the PHYSICAL ENTRY
  child entity is eliminated (since the only valid dircetive for
  DYNAMIC ENTRY is SHOW)...

    I agree with Chris Brienen.  Unfortunately the LAN Bridge 100 works
    as Chris described.  So, Chris suggested right way to modify the
    disposition of a learned address.
    
    "DELETE" directive will be supported in the "DYNAMIC" entity for the
    shake of LAB bridge 100.   The "PHYSICAL" entity will be obsoleted
    for DECmcc ELM V1.1.

    re. to 1790.3 & 1790.4
    
    	I agree with you that the only way is to use the DELETE command and
    then the CREATE, but the point is that I was only following the
    instructions of the course Student Guide: "the SET command to filter an
    address doesn't work. Use the CREATE command..."; and my students asked
    me why it didn't work.
    
    Many thanks and Best Regards to Chris & Jae

    should read:
    
    .
    of the course Instructor Guide: "the SET command to filter an
    .
    
    This is stated bluntly in the IG, not the SG, and left to the instructor 
    to present in whatever way he/she wishes.
    
    I don't have an MCC system available to me at the moment but,
    could someone try the create physical entry command on a LB100 and
    LB200 and post the success or failure here.  I'm 99.9% sure that it 
    worked for me.  I've noticed that memory starts to fail when you're
    >35, if I remember...
    
    Also, any descrepancies in the above mentioned course material should
    be forwarded to Jim Trant@BUO and Dick Tracy@LKG.
