So, assuming: - to get single value, the most beneficial is reguler SNMPGET (the lowest data traffic and the lowest proccessing load on agent). Is that right ?
SNMPGET = Get request SNMPWALK = GetNext SNMPBULKGET && SANPBULKWALK = GetBulk Thanks, czezz Dnia 24 maja 2012 10:43 Dave Shield <[email protected]> napisał(a): > On 24 May 2012 08:20, czezz <[email protected]> wrote: > > I am going to use SNMPBULKGET only. > > So, just to have a good understanding - in this case I will get no benefits > > comparing to regular SNMPGET, is this correct ? > > It doesn't really make sense to compare Get vs GetBulk. > They are doing two different tasks. > The more sensible comparison is between GetNext and GetBulk. > > > > With SNMPGET or SNMPBULKGET I request for specific OID > > and in my understanding I will always get singe value (eg. ifAdminStatus.1). > > Not quite. > > With the SNMP Get request, you ask for a list of (one or more) OIDs, > and receive the corresponding values - the same number as requested OIDs > (and for those precise OIDs).
