Usage Guidelines

Usage Scenario

To specify the type and number of a source interface with a specific IP address used to send SNMP trap messages, run the snmp-agent trap source command.

Configuration Impact

Trap messages carry IP addresses of the outbound interfaces, and the receivers can identify the source addresses.

Precautions

The source interface that sends trap messages must have an IP address configured.

After the snmp-agent trap source command is run, the private VPN where the source interface resides is automatically bound to the interface.

Rules for a destination host to select a VPN

Rule 1: If the snmp-agent target-host trap command is run with a specified source interface-type interface-number, the private VPN bound to the source interface is used to send trap messages. Otherwise, refer to rule 2.
Rule 2: If the snmp-agent trap source command is run to specify the source interface for trap messages globally, the private VPN bound to the source interface is used to send trap messages. Otherwise, refer to rule 3.
Rule 3: If the snmp-agent target-host trap command is run with a specified public-net, the public network is used to send trap messages. Otherwise, refer to rule 4.
Rule 4: If the snmp-agent target-host trap command is run with a specified vpn-instance vpn-instance-name, the host VPN is used to send trap messages. Otherwise, refer to rule 5.
Rule 5: If the set net-manager vpn-instance command is run to configure a global VPN, the global VPN is used to send trap messages. Otherwise, refer to rule 6.
Rule 6: The public network is used to send trap messages.

Example

# Configure the IP address of the interface as the source address for trap messages.
