Vyatta NOS documentation

Learn how to install, configure, and operate Vyatta Network Operating System (Vyatta NOS), which helps to drive our virtual networking and physical platforms portfolio.

Specifying trap destinations

To configure the destination of trap and inform notifications, specify the IP address (IPv4 or IPv6) of the SNMPv3 trap target and the name of the SNMPv3 user at the trap target. To authenticate the SNMPv3 user at the trap target, specify the service snmp v3 trap-target addr auth [ encrypted-key | plaintext-key ] passwd command. To encrypt the notifications at the trap target, specify the service snmp v3 trap-target addr privacy [ encrypted-key | plaintext-key ] passwd command.

By default, the vRouter sends inform notifications to trap targets.

The following table shows an example of the vRouter configured to send SNMP traps to the configured SNMP manager at 172.18.93.86.

To specify trap destinations, SNMPv3 user names at the trap target, and security keys, perform the following steps in configuration mode.
