SNMP Query Extreme-Stacking OIDs not found

[basti]

Hi,

actually i try to monitor the summit stack health for some of our x440-g2 switches in PRTG. For that i downloaded the 22.3.1.4_MIB file, splitted it up with the "Paessler MIB Splitting Tool" and extracted the Extreme-Stacking-MIB with the "Paessler MIB Importer" tool as OIDLIB-file. When i try to make an snmp-walk over this OIDLIB using "Paessler SNMP Tester", it only finds one accessible OID:

1.3.6.1.4.1.1916.1.33.1.0: EXTREME-STACKING-MIB|extreme stackable|extreme stack detection

But i would like to access 1.3.6.1.4.1.1916.1.33.2.1.3 (extremeStackMemberOperStatus). What am i doing wrong? Are there any additionally switch-side permissions to set?

1. SNMPv3-Credentials seem to be right (reading uptime and interface statistics is working perfectly)
2. Switch: X440-G2-48p-10G4
3. Image: 22.3.1.4
4. SNMP config:

code:

configure snmpv3 add user "SNMPv3User" engine-id 80:00:07:7c:03:02:04:96:9e:3f:fe authentication sha auth-encrypted localized-key xxx privacy aes 128 privacy-encrypted localized-key yyy
configure snmpv3 add group "v1v2cNotifyGroup" user "v1v2cNotifyUser1" sec-model snmpv2c
configure snmpv3 add group "v3group" user "SNMPv3User" sec-model usm
configure snmpv3 add access "v3group" sec-model usm sec-level priv read-view "defaultAdminView" write-view "defaultAdminView" notify-view "defaultAdminView"
configure snmpv3 add community "V2c-Trap" name "V2c-Trap" user "v1v2c_ro"
configure snmpv3 add community "private" name "private" user "v1v2c_rw"
configure snmpv3 add community "public" name "public" user "v1v2c_ro"
configure snmpv3 add community "v1v2cNotifyComm1" name "V2c-Trap" user "v1v2cNotifyUser1"
enable snmp access
disable snmp access snmp-v1v2c
enable snmp access snmpv3
disable snmpv3 default-group

Looks like a fake account..... or what did you realize exactly ?!
