3 Functions
3.1 Basic service functions
3.1.1 MAC address management
ZXR10 5250 series fulfills the following MAC functions:

Convert dynamic MAC address into static one
On one hand, the administrator expects that the user is fixed only to a port; on the other
hand, he does not want to configure too many static addresses. The function can be used
to reach the goal.

Bind MAC address to a port
Dynamic, static or permanent MAC address can be added to MAC address table. The
correspondence relation between static or permanent MAC address and port is fixed, and
cannot be cancelled until the address is deleted manually.

Limit MAC address number of a port
MAC address table capacity of a switch is limited. When many users are available and
MAC address table will reach the capacity limit, the MAC address number of low-priority
user port will be restricted.
The restriction can prevent MAC address broadcast to drive MAC address table to
overflow the network attack.

Port MAC address learning protection
When abnormal MAC address learning of a port is checked out, the switch will protect the
MAC address learning for some time. New address learning cannot be done in the
protection. When the protection expires, the port will be in the state of MAC learning
again.

Unknown-source MAC address filtering of a port
Unknown-source MAC address filtering of a switch port is closed by default, and the port
does not filter the unknown-source MAC address. If a switch port is configured with
enabling the unknown-source MAC address filtering, relative port will discard the packet
of unknown-source MAC address received at the port and learn it.
