Using the CLI to enable SNMP
Enter the following CLI command to enable SNMP:

Alternatively, you can use the set snmp on/off command and show snmp to show the current status of SNMP:

SNMP engine ID

The SNMP engine ID identifies the agent in the device and is a security feature of SNMPv3. Each SNMP packet
contains two engine IDs. One is used to identify security information – user name, key location. The second one
specifies where the packet payload is coming from and going to. The engine ID is automatically generated by the
system and is a product of the enterprise number of Network Critical (by IANA) and the MAC address of the
SmartNA-X ethernet interface, thus it is not user configurable.

Configuring SNMP notifications

You can enable SNMP notifications for health, SNMP, and system. When health notifications are enabled, traps or
informs, depending on how notifications have been configured, will be sent for the power, fan, and temperature
conditions. When SNMP notifications are enabled, traps or informs will be sent for SNMP cold or warm starts,
and SNMP authentication failures. For system notifications, traps or informs will be sent for link changes, TAP
module in/out, and traffic over or under a specified threshold level.
Using the web UI to configure SNMP notifications
Select the SNMP tab. Under "Send notifications", choose the notifications to send, or clear all notifications not
1.
to send any notifications. The following notifications are available (SNMP notification name in brackets):
Health
• System temperature over threshold (nctapNotifySysTemperature)
• TAP module temperature over threshold (nctapNotifyTemperature)
• Power on/off (nctapNotifyPower)
• Fan on/off (nctapNotifyFan)
SNMP
• System power up/down (coldStart)
• System restart (warmStart)
• SNMP authentication failure (authenticationFailure)
System
• Link up (linkUp)
• Link down (linkDown)
• Traffic high (nctapNotifyXSTrafficOver)
for information on the snmp enable agent command.
