udp-port port-number: Specifies the UDP port for SNMP notifications. If no UDP port is specified,
UDP port 162 is used.
vpn-instance vpn-instance-name: Specifies the VPN for the target host. The vpn-instance-name
argument specifies the name of the MPLS L3VPN, a case-sensitive string of 1 to 31 characters. If
this parameter is not specified, the target host is in the public network.
params securityname security-string: Specifies the authentication parameter. The security-string
argument specifies an SNMPv1 or SNMPv2c community name or an SNMPv3 username, a string of
1 to 32 characters.
v1: Specifies SNMPv1.
v2c: Specifies SNMPv2c.
v3: Specifies SNMPv3.
• authentication: Specifies the security model to be authentication without privacy. You must
specify the authentication key when you create the SNMPv3 user.
• privacy: Specifies the security model to be authentication with privacy. You must specify the
authentication key and privacy key when you create the SNMPv3 user.
Usage guidelines
You can specify a maximum of 20 SNMP notification target hosts.
Make sure the SNMP agent uses the same UDP port for SNMP notifications as the target host.
Typically, NMSs, for example, IMC and MIB Browser, use port 162 for SNMP notifications as defined
in the SNMP protocols.
If none of the keywords v1, v2c, or v3 is specified, SNMPv1 is used. Make sure the SNMP agent
uses the same SNMP version as the target host so the host can receive the notification.
If neither authentication nor privacy is specified, the security model is no authentication, no
privacy.
Examples
# Configure the SNMP agent to send SNMPv3 traps to 10.1.1.1 in the user public.
