Not sure what you are looking to tweak, but I think what you are looking for is:
Set clogsNotificationEnabled (220.127.116.11.18.104.22.168.22.214.171.124) to true by using the SNMP Set operation; for example, use the net-snmp set utility to set this OID to true from the linux command line using: snmpset -c -v2c 126.96.36.199.188.8.131.52.184.108.40.206.0 i 1
Set clogMaxSeverity (220.127.116.11.18.104.22.168.22.214.171.124) value by using the SNMP Set operation; for example, use the net-snmp set utility to set this OID value from the linux command line using: snmpset -c public -v2c 1 126.96.36.199.188.8.131.52.184.108.40.206.0 i
Enter a severity number for the setting. Severity values increase as severity decreases. A value of 1 (Emergency) indicates highest severity, and a value of 8 (Debug) indicates lowest severity. Syslog agent ignores any messages greater than the value that you specify; for example, to trap all syslog messages, use a value of 8.
Now, the above info is from the CUCM 7.1 Serviceability Admin guide. Which is a different document than 6.1 BUT, it is quite likely the above is applicable. For 6.1 and more information on how to configure the SNMP module then you should read through this:
