| Rahul,
The customer that I refered to in .0, is the same customer that is
refered to in 1921.7. I was the one that gave him the mib compiler
that he has had some success with. This is a new problem. 1921.11
refers to a new cabletron mib, would this help his problem?

| Contacted customer, he told me of an experiment he ran.
He edited the mib, and added a new entry to the portSourceAddr object
type index.
As supplied:
INDEX { boardIndex, portIndex }
::={commonP 4}
As Edited:
INDEX { boardIndex, portIndex, portIndex }
::={commonP 4}
He then recompiled the MIB and he could enter another index to the
request via the SMNP access module. This allowed him to retrieve
addresses, however it broke the rest of the commonP attributes.
He backed out the change.

I re-read your original note and it looks like the cabletron agent
has a bug. The object portSourceAddr is defined as follows in their
mib :
portSourceAddr OBJECT-TYPE
SYNTAX OCTET STRING
ACCESS read-only
STATUS mandatory
DESCRIPTION
"A source address that has been seen on this port."
INDEX { boardIndex, portIndex }
::= { commonP 4 }
The object identifier for commonP is "1.3.6.1.4.1.52.1.2.2.4.1".
According to SMI, to do a get operation on this object, the object
identifier specified should be :
"1.3.6.1.4.1.52.1.2.2.4.1.4.boardIndex.portIndex"
which is precisely what DECmcc is sending out in their PDU. The
reason why other management stations work is because they are
probably starting at the top of the table and doing a GetNext
operation to get the "lexinext" object, in which case the management
station does not need to specify the instance data.
Following the same argument the DECmcc command :
MCC> show snmp entity_name cabletron commonp * all attr
should work, but
MCC> show snmp entity_name cabletron commonp (x,y) all attr
should not work.
Can you tell the customer to try out the above to either
prove or disprove the premise.
Rahul.

| Rahul,
As you asked I had the customer, Martin Marietta, do the 'show' commands
you asked for. The customer is using the SNMP compiler supplied for
his original SNMP problem. So I expected both commands to work, which in
fact they did.
Attached is a partial log file of the output as well as a section from
anal/image for the compiler.
