Configuring the SNMP agent to send traps to a host
The SNMP module buffers the traps received from a module in a trap queue. You can set the size of the
queue, the duration that the queue holds a trap, and trap target (destination) hosts, typically the NMS.
To successfully send traps, you must also perform the following tasks:
•
Complete the basic SNMP settings and verify that they are the same as on the NMS. If SNMPv1 or
SNMPv2c is used, you must configure a community name. If SNMPv3 is used, you must configure
an SNMPv3 user and MIB view.
•
Make sure the device and the NMS can reach each other.
To configure the SNMP agent to send traps to a host:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Configure a target
host.
snmp-agent target-host trap
address udp-domain ip-address
[ udp-port port-number ]
[ vpn-instance
vpn-instance-name ] params
securityname security-string [ v1
| v2c | v3 [ authentication |
privacy ] ]
To send traps to a host, you must perform this
step to specify its IP address.
The vpn-instance keyword is applicable in an
IPv4 network.
3.
Configure the source
address for traps.
snmp-agent trap source
interface-type { interface-number
| interface-number.subnumber }
Optional.
By default, SNMP chooses the IP address of an
interface to be the source IP address of traps.
