This operation configures the Trap IP address and alarm reporting parameters for an upper-layer network management system (NMS). After the configuration, alarms of eReplication can be reported to the upper-layer NMS.
Northbound trap reporting parameters are used for communication between the upper-layer NMS and current eReplication. When parameters on the upper-layer NMS are changed, modify the parameters on current eReplication accordingly.
Configuring SNMP authentication information allows alarm information to be securely sent to a third-party NMS. SNMP supports SNMPv1, SNMPv2c, and SNMPv3. Enabling SNMPv1 and SNMPv2c brings security risks. You are advised to use only the secure SNMPv3 protocol.


Protocol Type |
Parameter |
Description |
Value |
|---|---|---|---|
SNMPv1 and SNMPv2c |
Read Community |
Indicates the community name authentication. If the Get or GetNext operation is performed, the read community name is used for authentication. |
The password must meet the following requirements:
|
Confirm Read Community |
Confirm the parameter settings. |
||
Write Community |
Indicates the community name authentication. If the Get operation is performed, the write community name is used for authentication. |
||
Confirm Write Community |
Confirm the parameter settings. |
||
SNMPv3 |
Username |
Northbound Trap username used by the upper-layer NMS and eReplication 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:
|
- |
|
Authentication Protocol |
Protocol used for verifying messages. The parameter value can be HMACMD5, HMAC_SHA1, HMAC_SHA2 or no protocol. |
[Example] HMAC_SHA2 NOTE:
The default value is HMAC_SHA2. HMACMD5 or HMAC_SHA1 is an insecure protocol which may cause security risks. Therefore, HMAC_SHA2(SHA256) 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:
|
|
Data Encryption Protocol |
Encryption protocol used for encapsulating data. The value can be DES or AES, or no encryption.
|
[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 default password is the same as that of the eReplication Agent. |
The password complexity requirements are as follows:
|
For SNMPv3, if Authentication Password is set in Trap parameter settings, you need to enter the authentication password. If Authentication Password and Data Encryption Password are set in Trap parameter settings, you need to enter the authentication password and data encryption password.
