Scenario 4: NMS wants to receive the v3Trap messages sent by the switch. 
The configuration on the switch is listed below: 
Switch(config)#snmp-server enable 
Switch(config)#snmp-server host 10.1.1.2 v3 authpriv tester 
Switch(config)#snmp-server enable traps 
Scenario  5: The  IPv6 address  of the  NMS is 2004:1:2:3::2; the IPv6 address of the switch 
(Agent)  is  2004:1:2:3::1.  The  NMS  network  administrative  software  uses  SNMP  protocol  to 
obtain data from the switch.  
The configuration on the switch is listed below: 
Switch(config)#snmp-server enable 
Switch(config)#snmp-server community rw private 
Switch(config)#snmp-server community ro public 
Switch(config)#snmp-server securityip 2004:1:2:3::2 
The NMS can  use private as the community string  to access the switch with read-write 
permission,  or  use  public  as  the  community  string  to  access  the  switch  with  read-only 
permission. 
Scenario  6:  NMS  will  receive  Trap  messages  from  the  switch  (Note:  NMS  may  have 
community string verification for the Trap messages. In this scenario, the NMS uses a Trap 
verification community string of usertrap). 
The configuration on the switch is listed below: 
Switch(config)#snmp-server host 2004:1:2:3::2 v1 usertrap 
Switch(config)#snmp-server enable traps
