bsnMLTHealthFailure

Module: BAY-STACK-NOTIFICATIONS-MIB

OID (symbolic): BAY-STACK-NOTIFICATIONS-MIB::bsnMLTHealthFailure

OID (numeric): 1.3.6.1.4.1.45.5.2.2.0.7

Node type: NOTIFICATION-TYPE

Description: This notification is generated when a receiving switch does not receive an expected number of autotopology frames on an MLT in a given time interval from the sending switch(es) on the other end of the MLT. Once notification has been sent, further notifications may be sent, but it is suggested these be at least 5 minutes apart. The ifAdminStatus object reflects the state of the port. The port may be partitioned by the switch or still be active depending on the detection algorithm's control parameters.

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> '' BAY-STACK-NOTIFICATIONS-MIB::bsnMLTHealthFailure
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.45.5.2.2.0.7

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]:55840->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (277358624) 32 days, 2:26:26.24
  SNMPv2-MIB::snmpTrapOID.0 = OID: BAY-STACK-NOTIFICATIONS-MIB::bsnMLTHealthFailure
