    Hi all, 

    i am new on aruba and i have a model that is not the same like 6300m, i configured snmpv3 enable

    the i add ip authorized-manager 10.10.10.10 access manager

    also snmpv3 user user1 auth sha pass priv aes256 pass

    and snmpv3 group managerpriv user "user1" sec-model ver3.

    for snmp3 do i need community?  the vrf context should be the default i dont use the oobm.

    did i forget something?

    Thanks alot.

    This is what I have on a 2930F, it probably is the same/similar on 2920 (PVOS/AOS-S):

    snmpv3 enable
    snmpv3 only
    snmpv3 restricted-access
    snmpv3 group managerpriv user "airwave" sec-model ver3
    snmpv3 user "airwave" auth sha "removed" priv aes "removed"
    

    Note that aes-256 is a 'non standardized' encryption for SNMPv3, there are different incompatible (vendor) versions of aes-256; so that may be a reason that it doesn't work. In that case try aes, which is aes-128 and see if that works.

    This is from my test 2920 managed via central.

    snmpv3 enable
    snmpv3 group managerpriv user "user-inform" sec-model ver3
    snmpv3 notify "name_xxxxxxxx" tagvalue "tag_xxxxxxxx"
    snmpv3 targetaddress "target_xxxxxxxx" params "param_xxxxxxxx" xx.xx.xx.xx taglist "tag_xxxxxxxx"
    snmpv3 params "param_10100055" user "user-inform" sec-model ver3 message-processing ver3 priv
    snmpv3 user "user-inform" auth sha "" priv aes ""

    As I'm aware only SHA-1 and AES-128 are supported.

    Best, Gorazd
