Hi,

I am getting below error configured SNMPV3 with password “wRlw1e8oCudR” (Raw 2.0.0p5 ). I tried both AES and CBC-DES also. SNMPv1 and SNMPV2c working fine. Only V3 showing error:

SNMP Error on : Error: passphrase chosen is below the length requirements of the USM (min=8).
snmpbulkwalk: (The supplied password length is too short.)
Error generating a key (Ku) from the supplied authentication

Hi Sharaf,

I thing the problem is in Your device you want to access check your snmpV3 settings in your device and verify the settings on the cli with:

snmpwalk -v3 -l authPriv -u -a <MD5|SHA> -A -x <AES|DES> -X

as example:

snmpwalk -v3 -l authPriv -u RO-USER -a SHA -A v3aut -x AES -X v3enc 10.125.xxx.xxx:161 1.3.6.1.2.1.1

Hi,

SNMPWalk is working fine. I can see the interface status also. Only Issue with SNMPV3 as you can see the image during the test

It would be good to see your real working SNMPwalk command.
You should also use snmpbulkwalk as this is used by CMK.

If it is only the test and all other things are working where is the real problem now?
