Command Usage
◆ To grant management access to an SNMPv3 user on a remote device, you must
first specify the engine identifier for the SNMP agent on the remote device
where the user resides. The remote engine ID is used to compute the security
digest for authentication and encryption of packets passed between the switch
and the remote user. (See “Specifying Trap Managers” on page 372 and
“Specifying a Remote Engine ID” on page 357.)
Parameters
These parameters are displayed:
◆ User Name – The name of user connecting to the SNMP agent.
(Range: 1-32 characters)
◆ Group Name – The name of the SNMP group to which the user is assigned.
(Range: 1-32 characters)
◆ Remote IP – The IPv4 address of the remote device where the user resides.
◆ Security Model – The user security model; SNMP v1, v2c or v3. (Default: v3)
◆ Security Level – The following security levels are only used for the groups
assigned to the SNMP security model:
■
noAuthNoPriv – There is no authentication or encryption used in SNMP
communications. (This is the default security level.)
■
AuthNoPriv – SNMP communications use authentication, but the data is
not encrypted.
■
AuthPriv – SNMP communications use both authentication and
encryption.
◆ Authentication Protocol – The method used for user authentication.
(Options: MD5, SHA; Default: MD5)
◆ Authentication Password – A minimum of eight plain text characters is
required.
◆ Privacy Protocol – The encryption algorithm used for data privacy:
■
3DES - Uses SNMPv3 with privacy with 3DES (168-bit) encryption.
■
AES128 - Uses SNMPv3 with privacy with AES128 encryption.
■
AES192 - Uses SNMPv3 with privacy with AES192 encryption.
■
AES256 - Uses SNMPv3 with privacy with AES256 encryption.
■
DES56 - Uses SNMPv3 with privacy with DES56 encryption.
◆ Privacy Password – A minimum of eight plain text characters is required.
