Module: TN-MGMT-MIB
OID (symbolic): TN-MGMT-MIB::tnIfSourceAddrLock

Description: The Source Address Lock when set to true(1) monitors for source MAC address change on this port. This feature is useful to detect if the device connected to this port has been changed and also for intrusion when unknown MAC address ingress this port.
What is tnIfSourceAddrLock?
This read-write boolean, when set to true, enables monitoring for a change in the source MAC address seen on this port. It helps detect both a legitimate device swap on the port and a potential intrusion attempt from an unexpected MAC address.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.3.1.4.3.1.1 snmpwalk -v2c -c public <target> TN-MGMT-MIB::tnIfSourceAddrLock
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.3.1.4.3.1.1.1 snmpget -v2c -c public <target> TN-MGMT-MIB::tnIfSourceAddrLock.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.868.2.5.3.1.4.3.1.1.1 s <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> tnIfSourceAddrLock.1
