3.1.3.1 GET/SET of MIB.
Response the request of PDU (Protocol Data Unit) corresponding to SNMPv3.
3.1.3.2 Send Trap
iPASOLINK can send SNMPv2-Trap and InformRequest initiatively to UDP Port
162. IP address of SNMP entity, security level, and user name are required to set the
Trap.
Authentic method and authentic password are required when the security level is
authNoPriv or authPriv. Encryption algorithm and encrypted password are required
when the security level is authPriv.
3.1.3.3 Security (user authentication, session management and
encryption)
SNMPv3 PDU is not authenticated by the community name as v1, v2c., but by the
user name, which requires the user registrations beforehand.
User authentication is carried out when the security level of the sent SNMP request is
authNoPriv or authPriv. The cryptographic hash function of the password is
selectable between MD5 and SHA.
Ciphered communication is enabled by the user authentication when the security
level of the sent SNMP request is authPriv. The cipher algorithm is selectable
between DES and AES. For the ciphered communication, a password must be set
when registering users.
User can also specify an SNMP Engine ID for each NE, which should be 16-byte
long and unique within the network.
