Chapter 4: Using SNMP
353
SNMP Sets and Thresholds
Some objects can be configured from the SNMP manager using SNMP
set commands. Objects that can be configured have a MAX-ACCESS level
of "read-write" in the MIB.
These objects include threshold objects, which causes the BCM2 to
generate a warning and send an SNMP notification when certain
parameters are exceeded. See
Sensor Threshold Settings
(on page 576)
for a description of how thresholds work.
Note: When configuring the thresholds via SNMP set commands, ensure
the value of upper critical threshold is higher than that of upper warning
threshold.
Configuring NTP Server Settings
Using SNMP, you can change the following NTP server-related settings
in the unitConfigurationTable:
•
Enable or disable synchronization of the device's date and time with
NTP servers (synchronizeWithNTPServer)
• Enable or disable the use of DHCP-assigned NTP servers if
synchronization with NTP servers is enabled
(useDHCPProvidedNTPServer)
•
Manually assign the primary NTP server if the use of DHCP-assigned
NTP servers is disabled (primaryNTPServerAddressType and
primaryNTPServerAddress)
• Manually assign the secondary NTP server (optional)
(secondaryNTPServerAddressType and
secondaryNTPServerAddress)
Tip: To specify the time zone, use the CLI or web interface instead. For
the CLI, see
Setting the Time Zone
(on page 417). For the web interface,
see
Setting the Date and Time
(on page 226).
When using the SNMP SET command to specify or change NTP servers,
it is required that both the NTP server's address type and address be set
in the command line simultaneously.
For example, the SNMP command to change the primary NTP server's
address from IPv4 (192.168.84.84) to host name looks similar to the
following:
snmpset -v2c -c private 192.168.84.84
firstNTPServerAddressType = dns firstNTPServerAddress =
"angu.pep.com"
