swPortSecPortMaxLernAddr
Module: DLINK-PORT-SECURITY-MIB
OID (symbolic): DLINK-PORT-SECURITY-MIB::swPortSecPortMaxLernAddr
OID (numeric): 1.3.6.1.4.1.171.12.63.3.1.1.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Indicates the allowable number of addresses to be learned on this port. The max entry range is (0..N). The value N means the max number and is determined by the project itself.
What is swPortSecPortMaxLernAddr?
This per-port integer sets how many MAC addresses port security is allowed to learn and lock as static entries on that specific port. Once the port reaches this learned-address count, further unknown source MACs are handled per the port's violation action, making this the primary per-port knob for limiting how many devices can attach. An admin securing a desk port that should only ever see one PC and one VoIP phone would set swPortSecPortMaxLernAddr to 2 on that port.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.63.3.1.1.1.2 snmpwalk -v2c -c public <target> DLINK-PORT-SECURITY-MIB::swPortSecPortMaxLernAddr
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.63.3.1.1.1.2.1 snmpget -v2c -c public <target> DLINK-PORT-SECURITY-MIB::swPortSecPortMaxLernAddr.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.12.63.3.1.1.1.2.1 i <value>
