10.15.1 Port Locking
When a port is locked, the following conditions exist:
• Any existing addresses for the selected port are cleared from the Unicast Table.
• If a MAC address was not entered, then the first address received on the port is locked in and is
the only source address recognized on that port.
• If a MAC address was entered, then that MAC address becomes the locked port address.
• Locked Port MAC addresses are displayed with a Status of Lock Port in the Static Unicast
Address Table Configuration Menu.
• On the LM Screen under Network Monitor Menu Unicast Address Table, the lock port MAC
address entries are displayed with an L.
• Locked Ports are stored in NVRAM and are retained through board resets.
• Re-locking a locked port will clear existing entries and start the lock procedure again, either
taking the next MAC address if no MAC entry was entered, or using the entered MAC address.
10.15.2 Unlocking the Port
When a port is unlocked, the following conditions exist:
• All locked entries for that port are cleared.
• New MAC Address entries will show up normally.
• Re-unlocking an unlocked port will have no effect.
