After you globally enable a trap function for a module, whether the module generates traps also depends
on the configuration of the module. For more information, see the sections for each module.
To enable the trap function:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable traps globally.
snmp-agent trap enable [ configuration | flash |
standard [ authentication | coldstart | linkdown |
linkup | warmstart ] * | system | wlan ]
Optional.
By default, all the traps
are enabled.
3. Enter interface view. interface interface-type interface-number N/A
4. Enable link state
traps.
enable snmp trap updown
Optional.
By default, the link state
traps are enabled.
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 check 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.
• 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 | ipv6
ipv6-address } [ udp-port port-number ]
params securityname security-string
[ v1 | v2c | v3 [ authentication |
privacy ] ]
If the trap destination is a host. The
ip-address argument must be the IP
address of the host.
3. Configure the source
address for traps. snmp-agent trap source interface-type
interface-number
Optional.
4. Extend the standard
linkUp/linkDown traps.
snmp-agent trap if-mib link extended
Optional.
By default, standard
linkUp/linkDown traps are used.
Extended linkUp/linkDown traps
add interface description and
interface type to standard
linkUp/linkDown traps. If the NMS
does not support extended SNMP
messages, use standard
linkUp/linkDown traps.
