1973.0. "DS900EF power up state" by DPDMAI::DAVIES (Mark, SCA Area Network Consultant) Tue Feb 07 1995 20:37

    DECswitch 900EF questions concerning power up state in a DEChub ONE
    configuration.  My customer will be using ONLY the front bezal ports of
    the DS900 and will only be passing TCP/IP between users on multiple
    shared ethernet LANs and a few servers on an FDDI LAN.
    
    After attaching the DEChub ONE and connecting the LANs to the front
    ports:
    
    1. Does the DS900EF come up like a standard bridge, ie, without any
       change/mods the unit will begin passing passing data between all
       front bezal ports.  TRUE?
    
    2. IP Fragmentation turned on by default.  TRUE?
    
    3. The FDDI ports are defaulted to A and B ports for DAS connection.
       TRUE?
    
    My customer's servers will be sending 2500+ byte packets to the
    ethernet users.  If this unit will satisfy the above two criteria, he
    wants 3 of them ASAP and then we can start talking about additional
    opportunities in his company.
    
    Thanks,

    Yes.

    No.  Need HUBWATCH to do that.
      
>>    3. The FDDI ports are defaulted to A and B ports for DAS connection.
    
    Yes.  They will accept M and S Ports as well as the usual DAS.

1973.2Hold state after power down?DPDMAI::DAVIESMark, SCA Area Network ConsultantWed Feb 08 1995 11:1712
    Concerning question #2:
    
    After changing the IP Fragmentation STATE = ON using HUBwatch, will
    it remain this way after power is removed?
    
    This would allow them to set each module up and then carry them to the
    specified locations.
    
    Thanks,

1973.3Yep, it's saved.NETCAD::GALLAGHERWed Feb 08 1995 11:436

Yes, it is saved in non-volatile memory and is preserved across power-ups.

    >> After changing the IP Fragmentation STATE = ON using HUBwatch, will
    >> it remain this way after power is removed?
         
    Yes this is a parameter stored in NVRAM. Resetting to factory
    settings would reset it back to the default state of off.

    Just a nit but you don't need HUBwatch for this.  Any SNMP NMS will do.

1973.8How to re-set custom settings in swapped modules?ROMEOS::HARRIS_MASales Executive IIWed Feb 08 1995 20:038
    one related question:
    	OK, the IP Fragmentation switch has now been enabled via Hubwatch,
    stored inside the module using NV ram, and the card fails...
    
    Field Service replaces the card. Can IP Fragmentation (or any setting
    for that matter) get re-set into the module AUTOMATICALLY?

If you painted your module blue, then it broke, then field service replaced
it with a new module, you would need to paint your module blue again.

Unless...

In an upcoming release of HUBwatch, there is a backup-and-restore function,
which does SNMP backups of device configurations, which can be restored at
a later date.  Coming soon.
