mstNewRoot

OID (symbolic): PRVT-SPANNING-TREE-MIB::mstNewRoot

OID (numeric): 1.3.6.1.4.1.738.1.5.107.0.4

Node type: NOTIFICATION-TYPE

Description: The newRoot trap indicates that the sending agent has become the new root of the MSTP; 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. Implementation of this trap is optional.

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> '' PRVT-SPANNING-TREE-MIB::mstNewRoot
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.738.1.5.107.0.4

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]:58151->[192.168.30.10]:162]:
