Second problem is that CMTS is not sending all trap messages when cable modem goes offline
What we lack are the messages that the modem goes offline (which are more importantly), and as far as online reaches 99% of messages. Something that we observed is that for example in the first 10 modems that we reset CMTS send traps for three only (not consecutive).After ten messsage CMTS send all of them (the test is usually reset the modem 20-30). There is not any connection about the type of modem that sends the trap.
Suspicion fell on PRE card but the tests were tried on various (2 CMTS with pre2, 2 CMTS with pre4 and 1 CMTS pre5). and different IOS from the SCF3 - SCH1.
Config is :
interface Cable3/0
cable enable-trap cmonoff-notification
cable enable-trap cmonoff-interval 60
snmp-server trap-source Loopback0
snmp-server enable traps cable cm-onoff
snmp-server host xx.xx.xx.xx public-cmts
snmp-server host xx.xx.xx.xx public-cmts
Thanks
