Configuring Alarm Reporting to the Upper-Layer NMS

Procedure

1. On the menu bar, select Settings.
2. In the navigation tree, choose Layered NMS > Trap Settings.
3. Configure the northbound Trap reporting parameters for the upper-layer NMS and UltraVR communicate with each other.

   If the northbound Trap reporting parameters of the upper-layer NMS are changed, those of UltraVR must be changed accordingly.

   1. In the Trap Parameters area, configure the northbound Trap reporting parameters for the upper-layer NMS and UltraVR communicate with each other. Table 1 describes related parameters.
      

      Table 1 Northbound Trap reporting parameters

      Parameter	Description	Value
      Username	Northbound Trap username used by the upper-layer NMS and UltraVR communicate with each other.	[Value range] The name contains 1 to 64 characters. [Example] user
      Environment Name	Name of the environment engine.	[Value range] The name contains 1 to 64 characters. [Example] sa
      Environment Engine ID	Unique identifier of an SNMP engine. This ID is used together with the environment name to determine an environment that uniquely identifies an SNMP entity. An SNMP message packet is processed only when the environments of the sender terminal and the recipient terminal are the same. Otherwise, the SNMP message packet will be discarded. This parameter supports two input modes: Hexadecimal input mode: The ID must be in the format of #**.**.**. The validity verification involves the value length and each hexadecimal value. The maximum length is 97 characters, including pound signs (#). Non-hexadecimal input mode: Enter the ID directly. The validity verification involves only the length. The maximum length is 32 characters.	-
      Authentication Protocol	Protocol used for verifying messages. The parameter value can be HMACMD5 or HMAC_SHA or no protocol.	[Example] HMAC_SHA NOTE: The default value is HMAC_SHA. HMACMD5 is an insecure protocol which may cause security risks. Therefore, HMAC_SHA is recommended.
      Authentication Password	If the authentication protocol is used to verify messages, you need to set the authentication password.	The password complexity requirements are as follows: Contains 8 to 64 characters. Must contain special characters, including !"#$%&'()*+,-./:;<=>?@[\]^`{_|}~ and spaces. Must contain upper-case letters, lower-case letters, and digits. Cannot be the same as the username or the mirror writing of the username.
      Data Encryption Protocol	Encryption protocol used for encapsulating data. The value can be DES or AES, or no encryption. DES: an international universal encryption algorithm. The key length is 56 bytes. AES: an advanced encryption standard. There are three types of key length: 128 bytes, 192 bytes, and 256 bytes. Different lengths provide different-level security protection.	[Example] AES NOTE: The default value is AES. DES is an insecure protocol which may cause security risks. Therefore, AES is recommended.
      Data Encryption Password	If the encryption algorithm is used for encapsulating data, you need to set the data encryption password.	The password complexity requirements are as follows: Contains 8 to 64 characters. Must contain special characters, including !"#$%&'()*+,-./:;<=>?@[\]^`{_|}~ and spaces. Must contain upper-case letters, lower-case letters, and digits. Cannot be the same as the username or the mirror writing of the username.

   2. Click OK.

4. Add the Trap IP address of the upper-layer NMS.
   1. In the Trap IP Address area, click Add.
   2. Configure IP Address and Port for the upper-layer NMS to receive alarms.
   3. Click OK.
