Optional
Enabled by default.
NOTE:
To enable an interface to send linkUp/linkDown traps when its state changes, enable the trap function of
interface state changes on an interface and
g
lobally. To enable the trap function on an interface, use the
enable snmp trap updown command. To enable this function globally, use the snmp-agent trap enable
[ standard [ linkdown | linkup ] * ] command.
Configuring trap parameters
Configuration prerequisites
To send traps to the NMS, make the following preparations:
• Complete basic SNMP configurations. Specify the SNMP version and community name if SNMPv1
or SNMPv2c is adopted. Set the username and MIB view if SNMPv3 is adopted. Configuration of
these parameters must be the same as on the NMS.
• Make sure that the device and the NMS can reach each other.
Configuration procedure
• After receiving the traps, the SNMP module processes the traps in one of the following ways:
• Saves the traps in the trap queue. If a network problem occurs, the trap queue caches the traps until
the network recovers. Then, the system sends the traps in the trap queue in turn. You can set the size
of the queue and the holding time of the traps in the queue,
• Sends the traps to the specified destination host (usually the NMS).
Follow these steps to configure trap parameters:
