newRoot

OID (symbolic): CHIPDOT1D-MIB::newRoot

OID (numeric): 1.3.6.1.4.1.49.2.4.14.0.1

Node type: NOTIFICATION-TYPE

Description: The newRoot trap indicates that the sending agent has become the new root of the Spanning Tree; the trap is sent by a bridge soon after its election as the new root, e.g., upon expiration of the Topology Change Timer immediately subsequent to its election.

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> '' CHIPDOT1D-MIB::newRoot
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.49.2.4.14.0.1

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]:59353->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (146587097) 16 days, 23:11:10.97
  SNMPv2-MIB::snmpTrapOID.0 = OID: CHIPDOT1D-MIB::newRoot
