swPortSecVLANMaxLernAddr
Module: PORT-SECURITY-MIB
OID (symbolic): PORT-SECURITY-MIB::swPortSecVLANMaxLernAddr
OID (numeric): 1.3.6.1.4.1.171.12.63.3.2.1.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Indicates allowable number of addresses to be learned on this VLAN. A value of -1 means no-limit. The default value is no-limit.
The max entry range is (0..N). The value N means the max number and is determined by the project itself.
What is swPortSecVLANMaxLernAddr?
This value is the number of MAC addresses allowed to be learned on this VLAN under port security, where -1 (the default) means no limit and N is the product-specific ceiling otherwise. Admins set a finite value here to cap address learning VLAN-wide rather than per port, useful in shared or trunked VLAN environments. Setting swPortSecVLANMaxLernAddr to 50 on a guest VLAN caps the total number of devices that VLAN will ever learn addresses for.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.63.3.2.1.1.2 snmpwalk -v2c -c public <target> PORT-SECURITY-MIB::swPortSecVLANMaxLernAddr
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.63.3.2.1.1.2.1 snmpget -v2c -c public <target> PORT-SECURITY-MIB::swPortSecVLANMaxLernAddr.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.12.63.3.2.1.1.2.1 i <value>
