UNICAST SERVICE CONFIGURATION
4.1.
MAC address management
MAC address management is a basic function of two-layer network management, including setting
MAC address aging time, limiting dynamic MAC address learning number and static MAC address.
4.1.1.
Dynamic MAC aging time
The aging dynamic MAC address can update the MAC address table in time, so that the system can
avoid not learning new MAC addresses, because of which the user data can not be forwarded.
After successfully configured MAC address aging time, the system will check the aging dynamic MAC
address. If at 1-2 times the aging time long range, there is no packet with the source MAC address,
the corresponding MAC address will be deleted from the MAC address table.
View the MAC address table entry:
OLT (config) # show mac-address
Note
:
The MAC address learning function is only for unicast MAC addresses and does not learn multicast
and broadcast MAC addresses.
MAC address table: the MAC address table saves in the system cache, whose table entries contain the
MAC address of the equipment connected to the system, the VLAN ID and the interface. When
forwarding data, query MAC address table according to the destination MAC address in the data
frame and the VLAN ID, the system can quickly locate the interface and thus to reduce the broadcast.
4.1.2.
Dynamic MAC Learn Number Limitation
Dynamic MAC address learning number of user ports or services can be set manually. When the MAC
address learned by the system reaches the configured maximum dynamic MAC address learning
number, the user port or service will not learn any other new MAC address. Restricting the number
of dynamic MAC address learning can limit the number of MAC addresses entering the network and
reduce the burden of network equipments. A dynamic MAC address can be aged, i.e., the system will
remove the MAC address table entries, if it does not send or receive messages within a specified
period of time from the equipment.
Configuration command:
GPON (config-xe1 / 1) # mac-address limit *
