To enable SNMP v2c on a managed FortiSwitch, the essential requirement involves configuring the SNMP agent and community strings:
Configure SNMP Agent and Communities (D):
SNMP Agent: Activating the SNMP agent on FortiSwitch allows it to respond to SNMP requests.
Community Strings: SNMP v2c uses community strings for authentication. These strings function as passwords to grant read-only or read-write access to the SNMP data.
Understanding Other Options:
Create an SNMP user (A) is necessary for SNMP v3, not v2c, as it involves user-based authentication and encryption.
Specify an SNMP host (B) is typically a part of SNMP configuration but not a requirement just to enable SNMP.
Enable SNMP v3 (C) is not related to enabling SNMP v2c.
