Hi,


I have configured SNMP v3 in my Cisco 3560 switch and added it into OpManager monitoring tool (supported SNMP v3).But it's showing SNMP not enabled in that device.SNMP v1 working fine.

Please find my SNMP (v3) configuration and let me know if I missed anything.



Switch(config)# snmp-server group admins v3 auth read adminview write adminview

Switch(config)# snmp-server user root admins v3 auth md5 secrte12 priv des56 secrte21

Switch(config)# snmp-server context opmanager

Switch(config)# snmp-server host 10.138.75.136 root


10.138.75.136 - OpManager server IP


Regards,

som

You did not post the configuration for the view adminview. Additionally, make sure OpManager supports SNMPv3 authPriv. Many applications which support SNMPv3 only support SNMPv3 authNoPriv.

First, this view is not sufficient to manage a Cisco device. You should consider using the built-in view v1default which will grant you all required MIB access. Second, udp/162 is not the correct port for SNMP. The SNMP agent binds to udp/161 for manager requests, and uses udp/162 to send SNMP notifications (e.g. traps).
