3209.0. "Questions to PORTswtiches,DECservers and Rep. 90T-16" by VNAED2::SEIDLER () Mon Jan 29 1996 02:29

Hello,

I have the following questions:

1. In the "Hubwatch for Windows - Use" manual (V4) there is on page 6-38 a 
picture of a port switching module (maybe PORTswitch 900CP). There is a check 
on a MAC field. For what is that. I do'nt have a Portswitch module, i just want 
to know. 

2. is the following ok or missed i something?
If i want to manage a DECserver 900TM in a HUB900 i have to enable SNMP, IP
... as discussed in diff. topics and to set it up in the "manage table" in
HUBwatch. I will see the Server in the front panel view, but cannot call
the server picture from that. If i want to manage the server i have to go into
the "Manage Table" and select the DECserver from it - with the result of a
picture showing and empty HUB900 just with that DECserver that you can then 
select. (the same with DECserver 90M and TL). If this is ok - will it be
changed or did i something wrong?

3. To manage a DECrepeater 90T-16 you need a DECagent 90. Is the following
possible? (I don't have yet any 90T-16, so i cannot try it)

               
	           DECagent 90       90T-16
			|               |
                        |               |
                      -----------------------
                                |
                              Bridge
                                |
                      ------------------------
			|		|
                        |               |
                      90T-16          90T-16

all modules standalone. Can i manage with the Agent90 all 90_T16?

many thanks in advance

Christian

	1. Maybe some other people can give a more full explaination, but many of the repeaters/portswitches have a MAC (Ethernet address). Using that check-box, you can assign the MAC to whichever port/group you want. 2. To manage a DECserver 900TM, do the required setup using one of the DECserver's ports (SNMP enabled, IP address assigned, etc). That's it. It doesn't need to be in the agents file and you don't have to do any- thing else to manage it. From that point on, just treat it like any other hub module. (From the hub's front panel view in HUBwatch, double click on the DECserver, and you're there.) 3. I don't think that will work - you also need at least a 90TS repeater in the same hub if the DECagent 90 is in a different hub. If I'm wrong, I'm sure some helpful people will correct me :-) Tom

	The 90T-16 is a "dumb" repeater, with no in-band management capability. The only way to manage it is to put it on the same management bus as a DECagent 90, 90TS, or 90FS (or in a DEChub900), which are all capable of acting as management agents for it. By management bus, I mean the async management bus built into a DEChub90 or DEChub900, or the async management bus in a MultiStack; this is not the LAN wire. Which is all the long-winded way to say it has to be in the same hub or stack as its management agent, it is not manageable over the LAN as you have illustrated.
