Chapter 35 Managing and Monitoring Using the CLI
Monitoring System Health and Status Using SNMP
•
For SNMPv1 and SNMPv2, you must specify a network from which SNMP GET requests are
accepted.

To use traps, an SNMP manager (not included in AsyncOS) must be running and its IP address
entered as the trap target. (You can use a hostname, but if you do, traps will only work if DNS is
working.)
entered as the trap target. (You can use a hostname, but if you do, traps will only work if DNS is
working.)
Use the
snmpconfig
command to enable and configure SNMP monitoring for the appliance. After you
choose and configure values for an interface, the appliance responds to SNMPv3 GET requests. These
version 3 requests must include a matching passphrase. By default, version 1 and 2 requests are rejected.
If enabled, version 1 and 2 requests must have a matching community string.

It is a good idea to poll for the hardware status and identify possible hardware failures before they
become critical. Temperatures within 10 per cent of the critical value may be a cause for concern.

Hardware Traps
Status change traps are sent when the status changes. Fan Failure and high temperature traps are sent
every 5 seconds. The other traps are failure condition alarm traps — they are sent once when the state
changes (healthy to failure).

changes (healthy to failure).
For example, on C170 appliances, traps are sent if the following thresholds are reached:
To see the available traps and threshold values on your appliance, run the
snmpconfig
command from
