RE: Netview PDU Packing Question

["Paul Maine Jr." <paulm@msicc.com>]

I have Netview NT and your suggested method does not appear to work for NT -
is there another means to set this for NT?

Thank You
Paul

Hi,

there is an option for snmpCollect:

  -m MaxMibPerPdu
       Collects values for the maximum number of MIB variables that can be
       requested for a PDU. To find out the default value, issue the
command
       snmpCollect ?.

Take a look at "man snmpCollect"

Kind regards
Oliver Bruchhaeuser

FWIW, my response is from an application program perspective.

How are you looking to perform this request?  With respect to the PDU as
declred in OVsnmpApi.h:
#define PDU_SIZE        (sizeof (OVsnmpPdu))

The PDU structure is only bounded by your memory contraints.  You could
declare a PDU with as many oids as you desire using 'OVsnmpVarBind
*variables'.

When you talk about 1500 bytes are you referring to ethernet packet size?
At the application layer multiple packets should have been re-assembled to
give you your entire request.



Hope this helps,

Subject: [NV-L] Netview PDU Packing Question


My question relates to the efficiency of how Netview performs SNMP
GetRequests during collection. I am aware that most SNMP agents today
support a maximum Protocol Data Unit (PDU) of 1500 bytes. Does Netview
support a PDU size of 1500 bytes?

If I enable Netview to collect 10 different MIB objects, will the SNMP
GetRequest include all 10 of the MIB objects in a single PDU or will
Netview
use 10 separate requests to obtain the information?

Thank You
Paul
