How to stop SNMP trap notifications to NOC operators console ??

Hi, - we have 8900 LTMs running 11.4.1 code. The issue we are having is that we need to suppress ( stop LTM from generating) large number of traps from going to Operations console. None of the instructions seen on F5 websites seem very clear as to how to do this. The link "http://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/tmos-implementations-11-1-0/21.html" is not very clear at all. In some place it says to modify "/etc/alertd/alert.conf" ...but then this link says " NOT TO". Below are the list of TRAPS we need to stop coming from the LTMs....Would it be possible to provide us with an example of how to go about achieving this. Time is really of the essence here. Many Thanks in advance John "5": - bigipCpuFanSpeedLow "11": - bigipServiceUp "13": - bigipNodeUp "16": - bigipActiveActive "18": - bigipFeatureOnline "40": - bigipGtmPoolAvail "41": - bigipGtmPoolNotAvail "43": - bigipGtmPoolEnabled "44": - bigipGtmLinkAvail "47": - bigipGtmLinkEnabled "48": - bigipGtmWideIpAvail "51": - bigipGtmWideIpEnabled "52": - bigipGtmPoolMbrAvail "55": - bigipGtmPoolMbrEnabled "56": - bigipGtmServerAvail "59": - bigipGtmServerEnabled "60": - bigipGtmVsAvail "63": - bigipGtmVsEnabled "64": - bigipGtmDcAvail "67": - bigipGtmDcEnabled "68": - bigipHardDiskFailure "69": - bigipGtmAppObjAvail "71": - bigipGtmAppAvail "77": - bigipGtmBoxAvail "79": - bigipAsmFtpRequestBlocked "80": - bigipAsmFtpRequestViolation "85": - bigipAsmSmtpRequestBlocked "86": - bigipAsmSmtpRequestViolation "100": - bigipGtmProberPoolEnabled "104": - bigipGtmProberPoolMbrEnabled "106": - bigipAvrAlertsMetricSmtp "134": - bigipDosAttackStop "135": - bigipLtmVsAvail "137": - bigipLtmVsEnabled "146": - bigipTrafficGroupActivate "147": - bigipPsPowerOn
