The alarm correlation-suppress enable target-host command enables NMS-based correlative alarm suppression.
The undo alarm correlation-suppress enable target-host command disables NMS-based correlative alarm suppression.
By default, NMS-based correlative alarm suppression is enabled. The system does not report correlative alarms to any NMS.
alarm correlation-suppress enable target-host ip-address securityname { security-name | cipher security-string } [ vpn-instance vpn-instance-name ]
alarm correlation-suppress enable target-host ipv6 ip-address securityname { security-name | cipher security-string } [ vpn-instance vpn-instance-name ]
undo alarm correlation-suppress enable target-host ip-address securityname { security-name | cipher security-string } [ vpn-instance vpn-instance-name ]
undo alarm correlation-suppress enable target-host ipv6 ip-address securityname { security-name | cipher security-string } [ vpn-instance vpn-instance-name ]
| Parameter | Description | Value |
|---|---|---|
| ip-address |
Specifies the IPv4 address of an NMS. |
The value is in dotted decimal notation. |
| securityname security-name |
Specifies the name of an NMS. |
The value is a string of 1 to 32 characters, spaces not supported. When quotation marks are used around the string, spaces are allowed in the string. |
| cipher security-string |
Specifies the cipher name of an NMS. |
A simple text password is a string of 1 to 32 case-sensitive characters. A ciphertext password is a string of 32, 48, 56, 68, or 68 to 168 case-sensitive characters. When quotation marks are used around the string, spaces are allowed in the string. Ciphertext passwords with various lengths configured in an earlier version are also supported in the existing version. |
| vpn-instance vpn-instance-name |
Specifies the name of a virtual private network (VPN) instance. |
The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string. |
| ipv6 ip-address |
Specifies the IPv6 address of an NMS. |
32-bit hexadecimal number, the format is x:x:x:x:x. |
Usage Scenario
If a network or device is working unstably, the device generates many alarms and sends them to an NMS, which deteriorates NMS performance after the NMS receives the alarms. To suppress correlative alarms to be sent to the NMS, run the alarm correlation-suppress enable target-host command to enable NMS-based correlative alarm suppression.
Prerequisite
The correlation-analyze enable command has been used in the alarm view to enable alarm correlation analysis.
