Conference netcad::hub_mgnt

944.0. "Hub update and info required" by LARVAE::HARVEY (Baldly going into the unknown...) Fri Apr 29 1994 06:18

   I am currently working on a major defence bid for the UK's RAF to supply LAN 
   infrastructures - DEChub and OPEN DECconnect - to some 66 bases world-wide, 
   though most are in the UK. 
 
   I don't want to go into too much detail at this point but the overall base 
   design for the sites will be FDDI backbone(s) with bridged ethernet 
   segments. Fibre cabling between buildings with UTP Cat 5 or fibre to the 
   desk according to security requirements. We propose staging the builds for 
   each site from a Digital location and sending them "shrink-wrapped" and 
   palletted ready to "plug and go" as far as possible - something that not 
   many of our competitors can offer !
 
   In terms of equipment used, we wish to minimise the list so as to keep 
   things very simple. This help in terms of module codification (NATO etc.) 
   and spares holdings, logistics and maintenance etc. (The KISS principle).
 
   Basically I need to know whether my selected DEChub modules will be affected 
   in terms of price/upgrades/new variants etc. and whether any new models may 
   help us be even more competetive.
 
   So far my choice of modules includes :-
 
   DEChub 900 M/S
   DECconcentrator 900MX
   DECbridge 900MX
   DECrepeater 900TM
   DECrepeater 900FP
   DECserver 900TM (for high-density terminal populations - tho' mostly PC's ?)
   DECrepeater 90TS ? (if 8 port + SNMP + AUI)
   DECrepeater 90FL ? (any plans for SNMP ?)
   DECserver 90TL (or just the M to avoid load host requirements)
   DECbridge 90FL (possibly - I may not use to reduce module count)
 
   With the above I can provide a good range of port densities high-low at 
   reasonable cost ie. we have to be VERY competetive 
 
   One design constraint being requested/mandated, is that no more than 20 
   users per ethernet segment are allowed. So using the 32 port repeater could 
   be a little wasteful. Will this device support "port-switching" (?) where 
   banks of ports can be assigned to separate backplane ethernet channels. If 
   not are we working on a new module which will ? If so, can anyone provide me 
   with the details please ?
 
   Same goes in terms of the 12 port fibre repeater in that we will need to 
   allocate its ports to separate network channels where it supports multiple 
   segments....
 
   I'm concerned that the "old" 90FA repeater doesn't have SNMP in it. Are 
   there plans to rectify (or replace) this ? There is a mandate for easy 
   management and I don't really want to start putting SNMP Agents all around 
   the place and push up costs !
 
   I'm aware of the 24 port 900 variants with the "telco" type socketry. All 
   well and good when hub mounted but not so clever in standalone DEChub ONE 
   configurations. Are there any plans to produce a 24 port RJ45 version ?
 
   I believe I'm right in that the new repeater 90TS has both SNMP and an AUI 
   port available on its standalone "docking station"... Any ideas of part 
   numbers and prices yet please ?
 
   This customer is also asking about SNMP II and OMNIPoint network management 
   - Government and GOSIP and so forth. I will look into another suitable 
   notesfile but does anyone have any news on these issues relevant to hubs ?
 
   Any ideas or pointers to people or documentation which will prove helpful 
   will be very much appreciated.
 
   Thanks in advance.

When 90 repeaters are installed in a DEChub900 managed by the Hub Manager
(as opposed to being managed by the DENMA) the Hub Manager provides proxy
management of the repeaters.  It provides proxy support for the MIB-II
system group, and for the repeater MIB (rfc1368 or rfc1516 depending on
the Hub Manager version).  The repeater MIB's mandatory "basic group"
is supported.  Some or all of the MIB's "address tracking" group(s) are
also supported.  (Contact Ann Marie Rhodes [newhub::rhodes] for details.)

If this level of MIB support is enough to satisfy your customer then you
won't have to "start putting SNMP around the place".

We would, of course, like to implement SNMPv2, but such activity has not
be started or even scheduled so I can't give you any dates.  What's 
OMNIPoint?  What's your customer asking about GOSIP?

    No.

    Not in any time frame you should be bidding on, certainly (that is,
    such things are still in the talking stage, not being built).
    
    What is wrong with Telco connectors in a DEChub ONE?  No - there are no
    plans for a 24 port RJ45 that I know of.
    
    I believe that the 90TS is a DETMI, but I don't know prices...
