mlxIBCARemoval

Module: MELLANOX-MIB

OID (symbolic): MELLANOX-MIB::mlxIBCARemoval

OID (numeric): 1.3.6.1.4.1.33049.2.5.5.3

Node type: NOTIFICATION-TYPE

Description: A channel adapter has been removed from the system. Removal of a CA means all its ports have also been removed (separate port removal events are not generated). SNMPv1 trap for this has mlxIBNotifications as the enterprise and 3 as the specific trap.

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> '' MELLANOX-MIB::mlxIBCARemoval
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.33049.2.5.5.3

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]:55474->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (379142834) 43 days, 21:10:28.34
