1958.0. "How to change Read Only community" by POBOX::ELARSON () Wed Feb 01 1995 18:04

    In the setup port for the Hub900, it's obvious how to change the
    Read/Write Community name.
    
    My customer has 14 Hub900's and would like to change the Read/Write
    Community but leave the Read Only as "public'.
    
    Can this be done... if so how?  Thanks in advance.

1958.1How to change or not change one of the communities?NETCAD::GALLAGHERWed Feb 01 1995 19:5032
I'm a little confused by your note.  Your title asks, "How to change 
Read Only community" yet the content of your note says your customer
wants to "change the Read/Write Community but leave the Read Only as 
"public'".  I'm just going to spew out some facts and hope I hit on
answering your question.

To change the read-only community you must set the 
"pcomSnmpAuthReadOnlyCommunity" object.  This object is in a MIB called,
"dec-hub900-hubmgr-mib-v1-1.txt".  The MIB is available via anonymous
ftp to gatekeeper.dec.com.  You can't use the console to change the
read-only community.  It was not deemed important or common enough to
warrant a menu item on the console.

To change the read-write community and leave the read-only community 
unchanged use the console to change the read-write community.  The read-only
community will remain unchanged.  Objects may still be read using
the read-only community ("public").  Sets may only be done using the
read-write community (whatever the customer selects).

Changing the read-only community without changing the read-write community
has no affect.  In other words, when the read-only community is "secret"
and the read-write community is "public" users will still be able to
(as the name implies) read and write using the community "public".
(Okay it has a subtle affect.  Users who use community "secret" will only 
be able to read.)

There is currently a bug in the Management Agent Module (MAM) which causes 
us to recommend that users reset the MAM after changing its read-write 
community.  (Note:  you don't have to reset a line-card after changing 
its read-write community - only the MAM.)  See note 1517.6 for more detail.

1958.2Spewed in the right direction...POBOX::ELARSONFri Feb 03 1995 14:319
    Shawn,
    
    Thanks for spewing out the facts.  You hit it right on the money.  My
    customer was concerned about intruders if he left the community name
    Read/Write as "public".  So all we do is change the community name via
    console port, and Read only stays public.  Exactly what the doctor
    ordered.  Thanks again.
