What is swL2PortSecurityMaxLernAddr?
Sets how many source MAC addresses (0-16) port security may learn and lock on this port; once that many are learned, packets from any further new source address are dropped, per the table's own description. Admins use this to cap a port to a known number of devices, e.g. 1 for a single workstation, as a basic anti-spoofing/anti-hub control.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.11.70.3.2.7.1.1.2 snmpwalk -v2c -c public <target> DGS3450-L2MGMT-MIB::swL2PortSecurityMaxLernAddr
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.11.70.3.2.7.1.1.2.1 snmpget -v2c -c public <target> DGS3450-L2MGMT-MIB::swL2PortSecurityMaxLernAddr.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.11.70.3.2.7.1.1.2.1 i <value>
