Create an SNMP group.
name:
 Enter the group name with 1 to 16 characters. The identifier of a group consists of a 
group name, security model and security level. Groups of the same identifier are recognized 
as being in the same group. 
v3: Configure the security mode for the group. v3 indicates SNMPv3, the most secure 
model.
noAuthNoPriv | authNoPriv | authPriv
: 
Choose a security level among noAuthNoPriv (no 
authorization and no encryption), authNoPriv (authorization and no encryption), authPriv 
(authorization and encryption). The default  is noAuthNoPriv. Please note that if you have 
chosen v1 or v2c as the security mode, the security level cannot be configured.
read-view: 
Set the view to be the Read view. Then the NMS can view parameters of the 
specified view.
write-view: 
Set the view to be the Write view. Then the NMS can modify parameters of the 
specified view. Please note that the view in the Write view should also be in the Read view. 
notify-view: 
Set the view to be the Notify view. Then the NMS can get notifications of the 
specified view from the agent. 
Step 3 show snmp-server group
Displays SNMP group entries.
Step 4 end
Return to Privileged EXEC Mode.
Step 5 copy running-config startup-config
Save the settings in the configuration file.
The following example shows how to create an SNMPv3 group with the group name as 
nms1, the security level as authPriv, and the Read and Notify view are both View1: 
Switch#configure
Switch(config)#snmp-server group nms1 smode v3 slev authPriv read View1 notify 
View1
Switch(config)#show snmp-server group
No.  Name   Sec-Mode  Sec-Lev  Read-View  Write-View  Notify-View
---  --------   ------------- ----------  ------------- ------------- --------------
1 nms1  v3  authPriv View1    View1
Switch(config)#end
Switch#copy running-config startup-config
