Module: ES1000-MIB
OID (symbolic): ES1000-MIB::swPortCtrlLockState
OID (numeric): 1.3.6.1.4.1.326.2.20.1.2.2.2.24.3.2.1.8

Type: INTEGER
Access: read-write
Description: The state of this entry. When the swDevCtrlTableLockState object is enabled, the state is not changed. When swVlanInfoStatus is in MAC-Base VLAN mode, this object is always disabled. The meanings of the values are:
other(1) - this entry is currently in use but the conditions under which it will remain so are different from each of the following values. disable(2) - Port lock funtion disable. enable(3) - Locking a port. Once the port is locked, it will not learn new SA addresses, and drop unknown/moved-SA packets forwarding to/from such ports. This is a way to prevent undesired traffic from being received or transmmited on the port. Note that locking a port doesn't lock the MAC address entries associated with the locked port, i.e. the existing address entries of the locked port will be age out even though it is locked.
What is swPortCtrlLockState?
Locks or unlocks a specific port's MAC address learning. Setting it to "enable" stops the port from learning new source addresses and drops traffic from unknown or moved MAC addresses, a way to prevent unauthorized devices from using that port.
