2.4.5 Typical SNMP Configuration Examples 
The IP address of the NMS is 1.1.1.5; the IP address of the switch (Agent) is 1.1.1.9. 
Scenario  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 1.1.1.5 
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  2:  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 enable 
Switch(config)#snmp-server host 1.1.1.5 v1 usertrap 
Switch(config)#snmp-server enable traps 
Scenario 3: NMS uses SNMP v3 to obtain information from the switch. 
The configuration on the switch is listed below: 
Switch(config)#snmp-server 
Switch(config)#snmp-server  user  tester  UserGroup  authPriv  auth  md5
