SNMP
3. Restart SNMP agent
Method 2:
Use the 'snmpusm' utility from a Redhat* Linux* host which has net-snmp packet install. You can
find the usage under http://www.net-snmp.org.
17.4 SNMP Trap Utility
The SNMP trap utility is utilized by the CMM Management software to send SNMP trap messages
to a remote application regarding any abnormal system events. When enabled, the CMM will issue
SNMP v1 traps on port 162. The CMM can also be configured to issue SNMP v3 traps. The SNMP
trap port can also be configured.
Note: If the “snmptrapversion” value is not in the cmm.cfg file or if the cmm.cfg file doesn't exist the
firmware will default to Trap Version 3.
17.4.1 Configuring the SNMP Trap Port
To configure the SNMP Trap Port to a different port number, issue the command:
cmmset -l cmm -d SNMPTrapPort -v [Port Number]
Where Port Number is the desired SNMP Trap Port number.
17.4.2 Configuring the CMM to Send SNMP v3 Traps
To configure the CMM to send SNMP v3 Traps, issue the command:
cmmset -l cmm -d SNMPTrapVersion -v v3
17.4.3 Configuring the CMM to Send SNMP v1 Traps
To configure the CMM to send SNMP v1 Traps, issue the command:
cmmset -l cmm -d SNMPTrapVersion -v v1
17.5 Configuring and Enabling SNMP Trap Addresses
The CMM allows up to five SNMP trap addresses destinations, SNMPTrapAddress1-5. In
redundant CMM systems, SNMP Trap Address 1 MUST be set to a valid IP address on the
network that the CMM can ping. This is used as a test of network connectivity as well as being
the first SNMP Trap Address.
When the CMM is configured to send SNMP v3 traps, it is recommended that only one
SNMPTrapAddress is configured due to the large amount of traps that can be generated on a loaded
system.
