2124.0. "DA90 and Autodiscovering" by MSDOA::LOVE (Do it with DNA) Mon Mar 20 1995 22:30

	My customer is having a problem getting his DA90 to autodiscover the
modules on three other DEChub90s.  Two of the hub90s are double units all four
hub sets have a Bridge90.  When the DECAgent is put in one of the single hub
sets it will autoconfigure that hub, and HUBWatch for windows will show the
modules and manage them.  Now how does he get the other three hubs to display?
His v1.1 DECagent manual instrucks him to add a community at the proper menu
item.  But his v2.1.3 DECagent does not have such a menu item.  Okay let us 
add it via HUBWatch, now he gets a blank hub displayed.  Okay, manually add the
modules, now he can manage the repeaters and servers but not the bridge.  Is he
running into a ECO mismatch on the bridges and agent?  The four hub sets are
connected via Repeater900FL in a DEChub 900.  Each repeater port is attached
interally to a separate LAN bridge via Switch900EF, could the DEChub 900 be 
getting in the way?

Yes, as you discovered, you must add additional communities to a DECagent
running V2.0 and later by using HUBwatch.

Can you be more specific on how the hubs are connected?  Is there a DECrepeater
90FA or 90FL in each DEChub 90 that is connected to the DECrepeater 900FL in the
DEChub 900, or are the bridges DECbridge 90FL's?  What is the firmware version
in the bridges?  V3.1 should be sufficient to manage the devices you described,
although there is a V3.9 available (see other notes for details).

As a wild guess, if you are not bringing the network in through the front panel
of the bridge, and the bridges are DECbridge 90's, you need to place a
T-connector with two terminators on the front panel ThinWire port (or a
thickwire terminator on the thickwire connection if that's selected via the
front panel switch).

2124.2HUBwatch management of remote brdg90 via DA90MSDOA::LOVEDo it with DNATue Mar 21 1995 19:2726
The configuration is:

Computer room - DEChub900 backbone with a DECrepeater900FP connected to five
DECbridge 90s.  Each DECbridge 90 is in a DEChub90.  Three of the DEChub90s are
doubled.  All but one of the single hub90 are fully populated with DECrepeaters
and DECservers.  The DEChub900 has two DECswitch900EFs joined together via an
internal FDDI ring using the A B ports.  Each of the DECrepeater ports are
connected to an internal 900 LAN and bridged via the DECswitch900.  Each node
of a three node VAX Cluster will also use a DECswitch900 port.  The DECagent 90
is in slot 7 of the non fully populated DEChub90.  Thus inorder for the
DECagent to communicate with a module on another HUB90 the message must pass to
its HUB90 backplane to the bridge90 through fiber to the DECrepeater900FP down
to a internal 900 LAN up to the DECswitch900 then backdown to another HUB900
LAN to another port on the DECrepeater900FP down fiber to the other DECbridge90
and finally to its backplane and the module.

  The DECagent only autoconfigures the HUB90 in which it resides.  He then
creates a community in HUBwatch and populates is manually.  Everything works
fine except he can not manage the remote bridge90 via HUBwatch.  He can manage
it via a VAX using NCP Connect.  By fine I mean he can manage the remote
repeaters and servers in the remote HUB90 but not the bridge90 in that same 
HUB.  The bridge90 in the same HUB90 as the DECagent is managed by HUBwatch.
He has HUBwatch for windows version 3.1.  It sure would help if he could
autoconfigure the remote HUB?

What happens when your customer double-clicks on the DECbridge 90's?

It is *supposed* to work.  

Is RBMS protocol (the DECagent 90 converts SNMP to RBMS to talk to the 
DECbridge 90) filtered anywhere on the network between the DECagent 90 and
the DECbridge 90?
2124.4FYIROGER::GAUDETBecause the Earth is 2/3 waterWed Mar 22 1995 14:003
The RBMS protocol type is 80-38.

2124.5Not my knowledgeMSDOA::LOVEDo it with DNAWed Mar 22 1995 21:175
    He has not turned on any filtering, but I will have him check.
    
    Thanks

2124.6Still have the problem!MSDOA::LOVEDo it with DNAThu Mar 23 1995 13:0016
    There are no filters on the network anywhere.  I think the problem is our
(his and mine) understanding of how to set up communities.  We went into the
out of band port and set the DA90's IP address and community name, "public-a"
to make it different from the HUB900's "public".  We then went into HUBwatch
and created the agent, agent-a.  When we activate it we get a window showing
the HUB with the bridge in slot 8, the DA90 in slot 7, the DECserver90L+ in 
slot 6, and a DECrepeater90T in slot 4.  The MUXserver90 in slot 5 does not
show up, as expected.  None of the other modules in remote DEChub90s show
up.  We then create other communities and manually enter the modules which
are bridges, repeaters, and servers.  We can manage from HUBwatch everything
but the bridges in the remote HUBs.  The bridge in the local HUB, the hub
in which the DA90 resides, is managed by HUBWatch fine.  What are we doing
wrong?
