swPortSecPortMaxLernAddr
Module: PORT-SECURITY-MIB
OID (symbolic): 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 value is the number of MAC addresses allowed to be learned and locked as static entries on this specific port, with N being the product-specific ceiling. Admins set it per port to control how many devices can be authenticated by MAC learning before the port stops accepting new addresses and starts dropping unknown traffic. Setting swPortSecPortMaxLernAddr to 1 on an access port restricts that port to only the first device it learns, blocking anyone who later plugs in a hub with additional devices.
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> 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> 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>
