swPortSecSysMaxLernAddr
Module: PORT-SECURITY-MIB
OID (symbolic): PORT-SECURITY-MIB::swPortSecSysMaxLernAddr
OID (numeric): 1.3.6.1.4.1.171.12.63.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Indicates the maximum number of addresses to be authorized by port security on the system. The max entry range is (1..N). The value N means the max number and is determined by the project itself.
What is swPortSecSysMaxLernAddr?
This value is the system-wide maximum number of MAC addresses that port security is allowed to authorize across the switch, with the actual ceiling N determined by the product's hardware limits. Admins use it as a global cap on learned/secured addresses to prevent the address table from being exhausted. Setting swPortSecSysMaxLernAddr near the switch's hardware limit ensures port security doesn't starve other MAC-table consumers of space.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.63.1.2 snmpwalk -v2c -c public <target> PORT-SECURITY-MIB::swPortSecSysMaxLernAddr
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.63.1.2.1 snmpget -v2c -c public <target> PORT-SECURITY-MIB::swPortSecSysMaxLernAddr.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.12.63.1.2.1 i <value>
