Followed this document to enable the snmp services for Vaap 14.4
https://techdocs.broadcom.com/us/en/symantec-security-software/identity-security/identity-suite/14-4/virtual-appliance/monitoring-virtual-appliance.html#concept.dita_623d8fec621bc878635f3ca9102edc2337ff98c7_MonitoringwithSNMP
Release : 14.4 (Centos8)
Component : IdentityMinder(Identity Manager)
The problem is because the procedure in documentation is for snmp v1 and v2.
Now Centos8 is delivered with snmp v3 that procedure is different.
14.4 onwards is using centos8 version.
Here is using SNMP Version 3(SNMPv3),
So the same configurations will not work as was disabled v1 and v2 SNMP configurations.
1) Stop snmpd service
service snmpd stop
2) Create a user to use for snmpv3, SHA is used for the authentication and AES for the encryption, for authentication you can use SHA|MD5 for encryption you can use AES|DES, please refer the snmpv3 documentation for more details.
net-snmp-create-v3-user -ro -A firewall -X firewall -a SHA -x AES snmpv3user
On successful creation of user, it will print something similar to this
adding the following line to /var/lib/net-snmp/snmpd.conf:
createUser snmpv3user SHA "firewall" AES "firewall"
adding the following line to /etc/snmp/snmpd.conf:
rouser snmpv3user
3)Start snmpd service
service snmpd start
4) Now use snmpwalk command to walk through the OID's and MIB's, Successful snmpwalk
should provide tons of output as follows
snmpwalk -u snmpv3user -A firewall -a SHA -X firewall -x AES -l authPriv 127.0.0.1 -v3
