newRoot
Module: LANART-AGENT
OID (symbolic): LANART-AGENT::newRoot
OID (numeric): 1.3.6.1.2.1.17.0.1
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> '' LANART-AGENT::newRoot snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.17.0.1
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
