Hi
I was trying to test the trap. I think router should send trap every 10
sec. But in actually it is sending every 30 sec. Any idea why?
config: ip multicast heartbeat 225.1.1.1 1 2 10
*Jun 9 05:46:32.196: SNMP: V1 Trap, ent ciscoExperiment.2.3.1, addr
192.168.100.1, gentrap 6, spectrap 1
ciscoIpMRouteHeartBeatEntry.2.225.1.1.1 = 0.0.0.0
ciscoIpMRouteHeartBeatEntry.3.225.1.1.1 = 10
ciscoIpMRouteHeartBeatEntry.4.225.1.1.1 = 2
ciscoIpMRouteHeartBeatEntry.5.225.1.1.1 = 0
*Jun 9 05:47:02.196: SNMP: V1 Trap, ent ciscoExperiment.2.3.1, addr
192.168.100.1, gentrap 6, spectrap 1
ciscoIpMRouteHeartBeatEntry.2.225.1.1.1 = 0.0.0.0
ciscoIpMRouteHeartBeatEntry.3.225.1.1.1 = 10
ciscoIpMRouteHeartBeatEntry.4.225.1.1.1 = 2
ciscoIpMRouteHeartBeatEntry.5.225.1.1.1 = 0
thank you - Arif
