NOC bilang ada high temperature yang disebabkan bahwa switch di RNC flapping. Memang sih ada flapping..
1554207: May 14 16:13:45 WIB: %SW_MATM-4-MACFLAP_NOTIF: Host xxxx.xx08.aa81 in vlan x00 is flapping between port VP3 and port Po1+Efpx00
1554208: May 14 16:13:45 WIB: %SW_MATM-4-MACFLAP_NOTIF: Host xxxx.xx09.5278 in vlan x00 is flapping between port VP3 and port Po1+Efpx00

kenapa bisa tau high utilization nya karena flapping?? katanya begini :
xxx-ME3600-xxx#sh processes cpu sorted
CPU utilization for five seconds: 93%/40%; one minute: 94%; five minutes: 94%

NOC said, " NLFM Learning Pr itu karena aktivitas MAC Learningnya"
Kenapa NOC berkata seperti itu? karena dia dapet info dari MSI like this :
MSI said, " di log ada flapping 1512929: May 13 09:40:01 WIB: %SW_MATM-4-MACFLAP_NOTIF: Host xxxx.xxc5.9b02 in vlan 900 is flapping between port Gi0/16+Efpx00 and port VP3".
Okey... lets see this..
xxx-ME3600-xxx#sh int des

Gi0/16 itu dalam kondisi down.. dan ... itu ga kekonect kemana-mana..
Lets see, what is the maksud of "NLFM Learn PR" based on
CSCtr82351
ME3600 crash after ospf configuration.
Router crashes when trying to change OSFP area/multipath parameters.
NLFM learning process causes CPU HOG and the router is forced to crash
by watchdog.
Workaround: None.
Yuk, sekarang terjemahnya dalam bahasa Indonesia versi google translate adalah (dengan sedikit modifikasi biar terjemahnya ga terlalu aneh):
CSCtr82351
ME3600 crash saat mencoba mengganti OSPF area/ parameter multipath nya. NLFM learning process menyebabkan CPU HOG dan router dipaksa untuk melakukan hal tersebut oleh watchdog.
Solusi: Tidak ada.
