Problem To Generate alarm from Trap

[Souaize]

Hi Guys,

i struggle since few days to generate an alarm from a trap.

I didn't configure a Trap Filtering Rule.

I received a trap for Link UP / Link DOWN -> i create a Trap to Alarm Rule wit OID  :

1.3.6.1.6.3.1.1.5.2.0-> Link down

1.3.6.1.6.3.1.1.5.3.0-> Link up

For Cisco Cat 2960X: No Alarm Generate from the trap.

For Cisco Cat 3560: No Alarm Generate from the trap.

For Cisco  Cat 3560G : Alarm is generate from the trap automaticaly without create a Trap to Alarm Rule.

For Cisco  Nexus 5K : Alarm is generate from the trap after creating a Trap to Alarm Rule.

I don't really understand why i have this difference because i create the rule with the IOD received in the trap.

Impossible to find some information so if someone have a solution, i will be really glad ;)

Regards
