Description: When the device has become the new root of the Spanning Tree, this object decides whether to send a new root trap.
What is swL2DevAlarmNewRoot?
Controls whether the switch sends an SNMP trap when it becomes the new Spanning Tree root bridge. Enabling this lets admins get alerted immediately if an unexpected device wins root election, which often signals a misconfiguration or a rogue switch.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.11.105.2.2.1.3.1 snmpwalk -v2c -c public <target> DES3528P-L2MGMT-MIB::swL2DevAlarmNewRoot
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.11.105.2.2.1.3.1.1 snmpget -v2c -c public <target> DES3528P-L2MGMT-MIB::swL2DevAlarmNewRoot.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.11.105.2.2.1.3.1.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> swL2DevAlarmNewRoot.1
