tnIfSourceAddrLockAction
Module: TN-MGMT-MIB
OID (symbolic): TN-MGMT-MIB::tnIfSourceAddrLockAction
OID (numeric): 1.3.6.1.4.1.868.2.5.3.1.4.3.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The 'tnIfSourceAddrLock' when set to true(1) monitors for source MAC address change on this port. This MIB variable sets the action to be taken when such an event is detected. 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. The actions performed on encountering an unknown address : discard(1) - The frame will unknown MAC are discarded. This is the default value. discardAndNotify(2) - A trap is sent to notify the intrusion/SA change and the frame is discarded. shutdown(3) - This will shutdown the interface on receiving the frame. all(4) - All the above actions take place. The frame is discarded, a trap is sent and the port is shutdown to prevent intrusion attack.
What is tnIfSourceAddrLockAction?
This read-write setting determines what happens when tnIfSourceAddrLock detects a source-MAC change on this port: discard (drop offending frames, the default), discardAndNotify (drop and send an SNMP trap), shutdown (disable the port), or all (do all three). An admin securing a physically-exposed port would choose 'all' to both stop the traffic and get alerted immediately.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.3.1.4.3.1.2 snmpwalk -v2c -c public <target> TN-MGMT-MIB::tnIfSourceAddrLockAction
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.3.1.4.3.1.2.1 snmpget -v2c -c public <target> TN-MGMT-MIB::tnIfSourceAddrLockAction.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.868.2.5.3.1.4.3.1.2.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> tnIfSourceAddrLockAction.1
