Flow Of Configuring Ethernet Services - Huawei OptiX OSN 550 Configuration Manual

4 Configuring Ethernet Services
MAC Address Table
The entries in the MAC address table reflect the corresponding relations between MAC addresses
and ports. The MAC address table contains the following entries:
l
l
l
NOTE
l If a routing entry is not updated within a specific period of time, that is, if the MAC address fails to be learnt
because the new data frame from the MAC address is not received, this routing entry is deleted automatically.
This mechanism is considered as aging, and this period of time is considered as the aging time. The aging
time of the MAC address table is five minutes by default and can be set by using the U2000.
l A limited number of MAC addresses can be learnt at a time.
Hub/Spoke
Generally, the central station and non-central stations can access each other, but the non-central
stations cannot access each other in the case of convergence services. Therefore, the ports
mounted to the bridge need to be defined as Hub or Spoke ports.

The mounted ports are Hub ports by default.

4.3 Flow of Configuring Ethernet Services

This topic describes the configuration processes related to Ethernet services. Before you
configure Ethernet services according to the flow, you need to complete the basic configurations
of the NEs according to the flow of creating a network.
4.3.1 Flow of Configuring EPL Services
The EPL services feature simplicity, transparent transmission, and dedicated bandwidth. The
configuration flow differs depending on whether Ethernet transparent transmission boards or
Ethernet switching boards are configured.
4.3.2 Flow of Configuring EVPL Services
In the case of EVPL services, services of different users share the bandwidth. Hence, the VLAN
ID or other schemes need to be used for differentiating the services of different users. If the

Dynamic entry
Indicates the entry that the bridge obtains by adopting the SVL/IVL learning mode. The
dynamic entry ages and is even lost after the Ethernet switching board is reset.
Static entry
Indicates the entry corresponding to the MAC address and the port that the network
administrator manually adds in the MAC address table on the U2000. A static entry is a
unicast entry. The static entry does not age and is not lost after the Ethernet switching board
is reset.
Blackhole entry
Indicates the entry used to discard the data frame that contains the specified destination
MAC address, and is also referred to as the MAC address disable entry. The blackhole entry
is configured by the network administrator. This entry does not age and is not lost after the
Ethernet switching board is reset.
Hub port
Hub ports can access each other. Hub ports and Spoke ports can also access each other.
Spoke port
Spoke ports cannot access each other. Hub ports and Spoke ports can access each other.
