It is capable of adding dynamic, static and permanent MAC addresses in MAC
address table. For static or permanent MAC address, the relationship between MAC
address and port is fixed. This relationship will not stop until it is removed manually.

Restrict the Number of Port MAC Address
The capacity of switch MAC address is limited. When the number of the user in the
network reaches the limitation of the MAC address table, we can restrict the number
of the learnt MAC address that the port of the users with low priority is.
By restricting port MAC address, MAC address flooding which easily causes MAC
address table overflow can be avoided.

Port MAC Address Learning Protection
When abnormity of one port MAC address learning is found, the switch will protect
this port MAC address learning for a while. As soon as the port goes into protection
mode, it will not carry out any new MAC address learning; when the protection is
due, the port can implement MAC learning again.

The Filtering of Port Unknown MAC Address
In default mode, the filtering service of unknown MAC address of switch port is
disabled. The port does not filter unknown MAC address. If unknown MAC address
filtering service is configured on one port of the switch, the corresponding port will
discard and learn the packets with the unknown MAC address got by this port.

MAC Address Filtering
The data filtering in terms of MAC address consists of the following three modes:


ZTE Confidential Proprietary
Only match the source MAC address of the data, i.e. if the source MAC
address of the data is the set MAC address, then carries out the filtering.
Only match the destination MAC address of the data, i.e. if the destination
MAC address of the data is the set MAC address, then carries out the filtering.
