THH??? are all Hub90
DecAgent90 (V2.1.3) in slot 7 in Hubs : THH010,THH050,THH090
Bridge90 (V3.4) in slot 8 in ALL hubs except THH010
All double hubs have the Backplane Serial Port (MMJ) connectors connected.
Repeater90T in hubs : THH010 (both 1 & 2)
                      THH020,THH030,THH030
                      THH050 (both 1 & 2)
                      THH090 (2 only)
Hub THH010 connects to "No Color" backbone using Repeater90FA AUI
Hubs THH050,THH080,THH090,THH0B0 and THH030 connect to backbone 
	using Bridge90 AUI connector.
Brouter90T2 V9.14(8) is in hub THH010 (1).
Hubwatch for Windows V3.1

Problems :
1) Agent90 in Hub THH010, THA917
   Cannot manage repeater90T in THH010 (2), hubwatch allows us to add the 
   repeater90t, displays it but when we doubleclick on it, the port nos. are
   not correct and the status of the port are all red even though stations are
   connected to the ports and are working.
   Also cannot add repeater90fa.
   By connecting the serial bus management backplane of both hubs of THH010,
   I thought that this is sufficient to manage repeaters in hub THH010 (1) even
   though there is on bridge in it. Am I correct?

   No response from Agent when double-clicking on Brouter90T2.
   Customer has added an agent for the brouter90t2 with the ip,community fields
   filled in, make that agent current. The brouter90t2 is then displayed but 
   when he double-clicks on it, he gets no response from agent.

2) Agent90 in Hub THH050, THA957
   Can manage repeaters90t in both hubs of THH050 ok.
   Customer added a new community THH080, then switch to that community.
   He was able to add the bridge90 and the bridge is displayed but when he
   double-clicks on it, he gets "bridge failed to get management information".
   However, if he added that community (THH080) under agent THA917, it works
   fine!!!

3) Agent90 in Hub THH090, THA997
   Can manage repeaters90t in both hubs of THH090 ok.
   Created other communites, THH0B0 THH0C0 THH0D0 THH0E0
   Addition of the bridges in these hubs was fine but he gets the following
   error message when double-clicking on the bridge :
   THH0B0	bridge failed to get management information
   THH0C0	no response from agent
   THH0D0	bridge failed to get management information
   THH0E0	no response from agent

   The customer also tried to add community THH0B0 under agent THA917 and it
   works there fine!!!
 

Thanks for all help
