In addition, SNMP managers can also be required to authenticate with agents before 
conducting SNMP management sessions.

SNMP v3 is enabled when you create SNMP groups and users. Once SNMP 
v3 is enabled, you must configure unique SNMP communities for SNMP v1 
and/or SNMP v2c access. 

The SNMP Engine ID is a unique identifier that identifies agents to the managers. The default 
SNMP Engine ID is the MAC address of the agent. You can change this. Use the SNMP 
EngineID screen to specify the Engine ID for the Switch.
Click SNMP > EngineID in the navigation panel to view the screen as shown.

You can also choose to have all managers in a group authenticate with agents. Use the SNMP 
Group screen to create SNMP groups. Click SNMP > Group to view the screen as shown.
