2820.0. "Stack and DEChub 90 management rules" by LFOIS1::MOUSSU (so unusuaL terM) Mon Oct 02 1995 09:51

  This is about management of modules in DEChub 90.
  We are well (all ?) aware now of what is possible or not in a Multistack 
  context as well as standalone rules and limitations.
  
  Having reviewed several notes here about DEChub 90 management I'm still 
  confused with rules CURRENTLY applicable.
  Is there a "management matrix" available anywhere ?
  
  My questions concern more precisely management of repeaters in a 8 or 16 
  slot DEChub90.
  
  - is a DECrepeater 90 FS/TS capable of bus mastering or:
  - is a DECbridge 90 (or DA 90) still necessary. In that last case, will a 
  DR90TS/90FS be able to act as a proxy agent ?
  - are DR 90T, 90C, 90FA manageable such a way
  
  In summary is the DEChub90 strictly equivalent, on the management side, to 
  the Multistack (with exception of slot restrictions).
  
  Moreover are there some restrictions in the DH 900 MS context using the MAM.

    >>  ... is a DECrepeater 90 FS/TS capable of bus mastering.
    
    Yes.
     
    >>  ... is a DECbridge 90 (or DA 90) still necessary. 
    
    The DA90 is not still necessary to manage the repeaters.  The DB90 is
    still necessary if you want to have a bridge function.
    
    >>  ... are DR 90T, 90C, 90FA manageable such a way
    
    Yes, the 90TS/90FS can managed repeaters.
    
    >>  In summary is the DEChub90 strictly equivalent, on the management 
    >>  side, to the Multistack (with exception of slot restrictions).
    
    Yes, it is.  The multistack is essentially a distributed DEChub 90.
    
2820.2Autodiscovery ?PRSSOS::PEYRACHEJean-Yves Peyrache Country Support Group FranceMon Oct 02 1995 11:338
re:-1


 do you mean that the autodiscovery function on FS/TS in DEChub90 works
 for 90TL ,90M ,Routeabout, DECpacketprobe ? or you need an Agent90 ?

    I'm not sure of the full and correct answer, so I'll defer to others.

2820.4Autodiscover? YesNETCAD::FORSBERGNIPG, Hub Products GroupMon Oct 02 1995 14:168
    The DECrepeaters 90TS and 90FS will _autodiscover_ all of the modules
    listed in 2820.2.  (This assumes that the DECserver 90TL has a recent
    software image that supports autodiscovery.)
    
    You do need a DECagent 90, however, to _manage_ any 90 module other
    than a repeater.

2820.7This is how as I did it.TROFS::WEBSTERNIS, London, CanadaTue Oct 17 1995 10:2420
	I recently upgraded serveral 90TS/FS with the latest code to support
	hub management.

	In order to make the TS/FS module the bus master, it must be placed
	in slot 7 or 8, then use the HUBwatch to select the module. Select
	community and manage current. In the lower right corner will be the
	bus master configuration. Select the module to be bus master and
	in the pull-down window, select DEChub 90. The module will reset
	and when selected again as current agent, the whole backplane will
	be seen. My demo hub has DR90C, DR90TS, DS90M, Dbr90T2, Packetprobe
	and DB90. All became visable.

	Once this was done, I am able to place the TS/FS in any slot I want
	and still see full management.

	Thanx to the HUBwatch/DEChub module engineering team for this cost-
	saving enhancement. I can now easily sell DEChub 90's in to small
	sites without the added cost of the DECagent.
