SNMP GetBulk command

Question

hi all,

i would like to know whether i can use the getbulk command with SNMPv1. If yes please let me know its adv... in no then what are the drawbacks.

Thanks in advance.

Uday.

Answer 1

No. That is determined by the protocol stack (GET BULK was introduced in v2 stack), not by other factors.

If you want to use GET BULK, you have to use SNMP v2 and v3, not v1.

Answer 2

It's worth noting that GETBULK is in v2c, which is a minor upgrade to SNMPv1 and thus supported by nearly every device these days even if the vendor didn't go to the trouble of doing SNMPv3 entirely.

SNMPv1: uses communities with V1 PDUs SNMPv2c: uses communities with V2 PDUs SNMPv3: uses multiple security modules with V2 PDUs

And then the SMI version numbers (1 and 2) can be used with any protocol unless there are SMIv2 datatypes which can't be accessed with V1 PDUs (eg, counter64).
