Enabling SNMPv3
The
snmpv3 enable
command allows the switch to: Receive SNMPv3 messages.
Configure initial users.
Restrict non-version 3 messages to "read only" (optional.)
IMPORTANT:
Restricting access to only version 3 messages makes the community named "public" inaccessible to network management applications (such as autodiscovery, traffic monitoring, SNMP trap generation, and threshold setting) from operating in the switch.
