switchNewRoot

OID (symbolic): SWITCH-BRIDGE-MIB::switchNewRoot

OID (numeric): 1.3.6.1.4.1.207.8.9.2.2.5.6.0.1

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. 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> '' SWITCH-BRIDGE-MIB::switchNewRoot
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.207.8.9.2.2.5.6.0.1

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]:61709->[192.168.30.10]:162]:

  SNMPv2-MIB::snmpTrapOID.0 = OID: SWITCH-BRIDGE-MIB::switchNewRoot

Start monitoring vendor-specific managed Ethernet switch, multi-VLAN bridge instances (per-VLAN STP status) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the SWITCH-BRIDGE-MIB::switchNewRoot OID value, configure state conditions and alerts, and monitor any vendor-specific managed Ethernet switch, multi-VLAN bridge instances (per-VLAN STP status) from a single console.
