swL2DevAlarmNewRoot
Module: SW-DES3x50-L2MGMT-MIB
OID (symbolic): SW-DES3x50-L2MGMT-MIB::swL2DevAlarmNewRoot
OID (numeric): 1.3.6.1.4.1.171.11.2.1.3.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: When the device has become the new root of the Spanning Tree, this object decide whether to send a new root trap.
What is swL2DevAlarmNewRoot?
Controls whether the switch sends an SNMP trap when Spanning Tree elects it as the new root bridge; an admin enables(3) this to get alerted whenever a topology change promotes this switch to root, which often signals an unplanned STP recalculation elsewhere in the network.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.11.2.1.3.1 snmpwalk -v2c -c public <target> SW-DES3x50-L2MGMT-MIB::swL2DevAlarmNewRoot
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.11.2.1.3.1.1 snmpget -v2c -c public <target> SW-DES3x50-L2MGMT-MIB::swL2DevAlarmNewRoot.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.11.2.1.3.1.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> swL2DevAlarmNewRoot.1
