Item Description
User Name Specifies the name of the SNMP user being added for the User-based
Security Model (USM). Each user name must be unique within the
SNMP agent user list. A user name cannot contain any leading or
embedded blanks.
Group Name A SNMP group is a group to which hosts running the SNMP service
belong. A group name parameter is simply the name of that group by
which SNMP communities are identified. The use of a group name
provides some security and context for agents receiving requests and
initiating traps and does the same for management systems and their
tasks. An SNMP agent won't respond to a request from a manage-
ment system outside its configured group, but an agent can be a
member of multiple groups at the same time. This allows for commu-
nications with SNMP managers from different groups.
Engine ID Each SNMPv3 agent has an engine ID that uniquely identifies the
agent in the device. If given this entry will be used only for packets
whose engine id is this. This field takes an hexadecimal string in the
form 0102030405.
Authentication Specifies the authentication protocol to be used on authenticated
messages on behalf of the specified user.

SHA: SHA protocol will be used.

MD5: MD5 protocol will be used.

None: No authentication will be used for this user.
Privacy Specifies the privacy protocol to be used on encrypted messages on
behalf of the specified user. This parameter is only valid if the Authen-
tication method parameter is not NONE.

DES: DES protocol will be used.

None: No privacy protocol will be used.
