hwMstpiBridgeLostRootPrimary

Module: HUAWEI-MSTP-MIB

OID (symbolic): HUAWEI-MSTP-MIB::hwMstpiBridgeLostRootPrimary

OID (numeric): 1.3.6.1.4.1.2011.5.25.42.4.2.3

Node type: NOTIFICATION-TYPE

Description: The SNMP trap that is generated when the bridge is no longer the root bridge of the instance. Another switch with higher priority has already been the root bridge of the instance.

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> '' HUAWEI-MSTP-MIB::hwMstpiBridgeLostRootPrimary
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.2011.5.25.42.4.2.3

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]:58666->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (138836778) 16 days, 1:39:27.78
  SNMPv2-MIB::snmpTrapOID.0 = OID: HUAWEI-MSTP-MIB::hwMstpiBridgeLostRootPrimary
