• System Location (optional): For example, Thornton (could be a site location name, city name, etc.)

• System contact and email: For example, John Kennedy jkennedy@yourdomain.com

• System description (optional): For example, Avaya ASP 130 R6.0.x – (host FQDN)

• Do you want to enable SNMPv1/SNMPv2c access? y/n: n

• Do you want to enable SNMPv3 access? y/n: y

• Do you want to add/change an SNMPv3 user y/n: y

• Enter the SNMPv3 username, for example: Test1v3

• Enter the index of the authentication hash type: (0=SHA, 1=SHA-224, etc…) e.g. 1

  Note:

  SHA/SHA1 is considered deprecated and, therefore, vulnerable to security scanners.

• Enter the Authentication PassPhrase, for example: avaya123

  Note:

  This field is mandatory and requires a minimum of 8 characters.

• Re-enter the Authentication PassPhrase, for example: avaya123

• Enter the index of the Encryption algorithm: (0=AES, 1= AES-192, etc…) e.g. 0

• Enter the Encryption PassPhrase, for example: avaya123

  Note:

  This field is mandatory and requires a minimum of 8 characters.

• Re-enter the Encryption PassPhrase, for example: avaya123

• Do you want to add/change an SNMPv3 user y/n (optional): n

  Note:

  In this example, a single SNMPv3 will be configured but multiple users can be configured at the same time.

• Do you want to add SNMPv1 trap receivers? y/n: (n) n

• Do you want to add SNMPv2c trap2 receivers? y/n: (n) n

• Do you want to add SNMPv2c inform receivers? y/n: (n) n

• Do you want to add SNMPv3 trap receivers? y/n: (n) y

  #### System will display Existing SNMPv3 users previously created e.g: Test1v3 ####

• Enter the IP/FQDN of the host receiving the traps: e.g. 192.168.10.254

• Enter the optional host port where to send the traps: 162 is the default value and will be used in this example.

• Do you want to add another SNMPv3 trap receiver? y/n (optional): n

  Note:

  In this example a single trap receiver will be configured, however, multiple trap receivers can be configured at the same time.

• Do you want to add SNMPv3 inform receivers? y/n: (n) (optional)

  Note:

  In this example inform receivers are not configured. SNMP inform traps require the SNMP manager (NMS Tool) to send an acknowledgment that it received the inform trap (get-response), therefore providing more reliability. If the manager does not acknowledge the inform trap, the agent will retry sending the inform trap a certain number of times. Both inform trap and snmp trap carry the same information.
