By default, SNMP notification
logging is disabled.
Configuring SNMP notifications
The SNMP Agent sends notifications (traps and informs) to inform the NMS of significant events, such as
link state changes and user logins or logouts. Unless otherwise stated, the trap keyword in the command
line includes both traps and informs.
Enabling SNMP notifications
Enable an SNMP notification only if necessary. SNMP notifications are memory-intensive and might
affect device performance.
To generate linkUp or linkDown notifications when the link state of an interface changes, you must
enable linkUp or linkDown notification globally by using the snmp-agent trap enable standard
[ linkdown | linkup ] * command and on the interface by using the enable snmp trap updown
command.
After you enable notifications for a module, whether the module generates notifications also depends on
the configuration of the module. For more information, see the configuration guide for each module.

By default, SNMP
configuration notifications,
standard notifications, and

SNMP notifications are
enabled varies with
modules.

4. Enable link state
notifications.
enable snmp trap updown
By default, link state
notifications are enabled.
Configuring the SNMP agent to send notifications to a host
You can configure the SNMP agent to send notifications as traps or informs to a host, typically an NMS,
for analysis and management. Traps are less reliable and use fewer resources than informs, because an
NMS does not send an acknowledgement when it receives a trap.
