swPortSecPortLockAddrMode
Module: PORT-SECURITY-MIB
OID (symbolic): PORT-SECURITY-MIB::swPortSecPortLockAddrMode
OID (numeric): 1.3.6.1.4.1.171.12.63.3.1.1.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Indicates the mode of locking address. In deleteOnTimeout(2) mode, the locked addresses can be aged out after the aging timer expires. In this mode, when the locked address is aged out, the number of addresses that can be learned has to be increased by one. In deleteOnReset (3) mode, locked addresses never age out unless the system restarts which will prevent port movement or intrusion.
What is swPortSecPortLockAddrMode?
This setting controls how locked MAC addresses on this port age out: permanent addresses never expire, deleteOnTimeout addresses age out after the aging timer and free a learning slot, and deleteOnReset addresses persist until the switch restarts. Admins choose the mode based on whether they want locked addresses to adapt over time or stay fixed for tighter security. Setting swPortSecPortLockAddrMode to deleteOnReset(3) on a secure server port ensures a learned address can't be replaced by an attacker's MAC without a full switch reboot.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.63.3.1.1.1.3 snmpwalk -v2c -c public <target> PORT-SECURITY-MIB::swPortSecPortLockAddrMode
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.63.3.1.1.1.3.1 snmpget -v2c -c public <target> PORT-SECURITY-MIB::swPortSecPortLockAddrMode.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.12.63.3.1.1.1.3.1 i <value>
