cmRoleChange
Module: COPPER-MOUNTAIN-NETWORKS-DSL-MIB
OID (symbolic): COPPER-MOUNTAIN-NETWORKS-DSL-MIB::cmRoleChange
OID (numeric): 1.3.6.1.4.1.1996.0.28
Node type: NOTIFICATION-TYPE
Description: This trap is sent whenever an SCM changes role from Primary to Secondary, or from Secondary to Primary. If this trap has a severity of 'information,' it can potentially clear an alarm in the system. When such a trap is received by the manager, the operator can query the cmTrapCriticalCount, cmTrapMajorAlarmCount, and cmTrapMinorAlarmCount objects to get the current system alarm status.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' COPPER-MOUNTAIN-NETWORKS-DSL-MIB::cmRoleChange snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.1996.0.28
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
Example snmptrapd log entry:
zoo11-linux.zoo [UDP: [192.168.30.111]:54188->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (447139756) 51 days, 18:03:17.56 SNMPv2-MIB::snmpTrapOID.0 = OID: COPPER-MOUNTAIN-NETWORKS-DSL-MIB::cmRoleChange
