are two types of notification mechanisms supported by the Switch. 

• SNMP Notification - SNMP traps are sent to external SNMP management stations.
• Authentication Notification - Failed authentication attempts are logged by the Switch.

Use the SNMP Notification section of the SNMP Trap Station screen to enable the 
notification mechanisms. Click SNMP > Trap Station to view the screen as shown.

authenticate messages that are sent between the management station (the SNMP 

manager) and the device (the SNMP agent). The community string is included in 

every packet that is transmitted between the SNMP manager and the SNMP agent.
