5345.0. "Problem with using DecHub (from DecMcc) to manage mulitple hubs" by GIDDAY::WAN (Denny Wan, Sydney CSC) Thu Jul 15 1993 23:06

I had read the discussion in note 5090 & 4625 about the problem of partial
registration of foreign devices such as DecHub. I managed to partially register
a few more DecHubs (with no resident DecAgent in them) and nomiated another 
DecAgent as the proxy agent. The normal DecMcc command works fine on these hubs.
But when I tries to fire up HubWatch from DecMcc on these hubs, I got an error 
saying "Attribute Not Gettable". I guess the reason is that HubWatch is looking 
for the IP address of the Hub rather than the proxy agent and thus it failed. 
Is there any way to workaround this problem ie to fire up HubWatch to look
into the secondary hubs directly?

Cross posted in Hub_mgnt conf.

The DecMcc entity attributes of these hubs are shown as belows. 
.ip.decagent90 is the primary hub with a resident Decagent90.
.ip.denny_hub_2 is a secondary hub using the Decagent90 in .ip.decagent90 as
its proxy agent.

Denny.

	The foreign devices (in your case the hubs without a DECagent) have 
	neither an IP Address, nor an Internet Name. So, when you launch 
	HUBwatch none of these identifiers can be passed to the application. 
	I can't think of any way to launch HUbwatch directly on the secondary
	hubs. Maybe someone has some ideas regarding this.

5345.2Can be done fairly easilyWELLIN::MCCALLUMWed Nov 03 1993 03:5813
    
    The launch procedure could be updated to pass the proxy agent address
    through to the command procedure as well as a community name and thus
    make it work.
    
    What I have done is to use a reference icon for each hub and proxied
    hub, and use its reference attributes for agent name and community
    name. You can then start hubwatch for any hub by clicking on the
    appropriate reference icon. I put the reference icon next to the
    appropriate agent icon.
