Some question about the DEC agent 90 capabilities and performance. Assume a LAN where 10 Hub 90s should be installed. Each hub contains one DECbridge 90, and two DECrepeater 90Ts. Is it possible to make the management of all this configuration by installing one DECagent 90 into one of the hubs (and HUBwatch)? Or should there be more agents? I'm confused by the V2 announcements stating 16 communities or 64 modules - how do these numbers translate into real configurations (with hub 90s and/or with standalone modules). Thank you for an answer and help. Petr.

Petr,
You should be all set since you didn't break either the community
or module rule. Each of the 10 hubs will be a community (<16) and
you have 32 or so modules (agent and bridge in one hub) (<64).
Regards,
Bob

With a single DECagent 90 you can manage up to 16 communities. A community is either a hub (DEChub 90 or 900), a double hub (two daisy-chained DEChub 90s), or a standalone module. Within each community there are modules (up to the maximum the community type will support; 8 for a hub, 16 for a double hub and 1 for a standalone). So depending on your configuration, you can mix and match devices into communities such that a single DECagent 90 is managing no more than 16 communities which collectively contain no more than 64 modules. Simple maximum configurations can be: - 4 fully populated double hubs (4 hubs with 16 modules each = 64 modules) - 8 fully populated hubs (8 hubs with 8 modules each = 64 modules) - 16 standalone modules (16 communities of 1 module each) - a mixture of not fully populated hubs and/or standlone modules such that the 16 community or 64 module limits are observed (which looks like your case). In your configuration, 10 DEChub 90s can be managed by a single DECagent 90 provided that the total number of modules in those 10 hubs does not exceed 64 (which it could if they were all fully populated). Given the devices you specified, you are well within the limits since you will have 10 communities containing a total of 31 modules (10 bridges, 20 repeaters and 1 DECagent 90). How's that? ...Roger... DECagent 90 devo | |||||
