Description 
Use the snmp-agent group command to configure a new SNMP group and specify its access right. 
Use the undo snmp-agent group command to delete a specified SNMP group. 
By default, SNMP groups configured by the snmp-agent group  v3  command use a 
no-authentication-no-privacy security model. 
An SNMP group defines security model, access right, and so on. A user in this SNMP group has all 
these public properties. 
Related commands: snmp-agent mib-view, snmp-agent usm-user
Examples 
# Create an SNMP group group1 on an SNMPv3 enabled device, no authentication, no privacy.

Default Level 
3: Manage level 
Parameters 
engineid: Engine ID, an even number of hexadecimal characters, in the range 10 to 64. Its length must 
not be an odd number, and the all-zero and all-F strings are invalid. 
Description 
Use the snmp-agent local-engineid command to configure a local engine ID for an SNMP entity. 
Use the undo snmp-agent local-engineid command to restore the default local engine ID. 
By default, the engine ID of a device is the combination of company ID and device ID. Device ID varies 
by product; it could be an IP address, a MAC address, or a self-defined string of hexadecimal numbers. 
An engine ID has two functions: 
For all devices managed by one NMS, each device needs a unique engine ID to identify the SNMP 
agent. By default, each device has an engine ID. The network administrator has to ensure that 
there is no repeated engine ID within an SNMP domain. 
In SNMPv3, the user name and cipher text password are associated with the engine ID. Therefore, 
if the engine ID changes, the user name and cipher text password configured under the engine ID 
become invalid. 
Typically, the device uses its default engine ID. For ease of remembrance, you can set engine IDs for 
the devices according to the network planning. For example, if both device 1 and device 2 are on the
