Hi LSA,

The two commands have different functions.

As wissal said, the snmp-agent community command is used to configure the SNMPv1 / SNMPv2c.

The implementation of SNMP v3 is different from that of v1/v2c. Instead of using the community, SNMP v3 adds encryption and authentication functions.

The snmp-agent group command can be used to configure the encryption and authentication modes. 

And the snmp-agent usm-user command can be used to configure the algorithm and password.

Hello,

Function

The snmp-agent community command configures the SNMPv1 or SNMPv2c read-write community name.

Function

The snmp-agent group command creates an SNMP group by mapping SNMP users to SNMP views.


if we have community is read-only & snmp-agent group is read & write both ,,,, 

Then NMS will read only means actually read write function depend on what community.

Thanks

@LSA hi,
I think, snmp-agent community assigns the detailed actions while the snmp-group assigns the SNMP view.
It feels like the snmp-agent community indicates how to do, and the snmp-group indicates where to do.
