Ethernet Service Forward Mode Management

If native E-Line services are configured between two Ethernet ports on an EM6T, EM6F, EM6TA, or EM6FA board, the board can forward the services directly after Ethernet Service Forward Mode is set to Local. Then the native E-Line services can be transmitted using large bandwidths. For other types of services and services with ports in link aggregation groups (LAGs), the largest port bandwidth can only be 500 Mbit/s due to backplane bandwidth limitations.

In the NE Explorer, choose Configuration > Ethernet Service Forward Mode Management from the navigation tree.

Parameter Description

Parameter	Value	Description
NE Name	For example: NE102	Indicates the NE name.
Ethernet Service Forward Mode	Local, Center Default: Center	Indicates the Ethernet service forwarding mode of the NE. The options are as follows: Center: intra-board Native E-Line services must be forwarded through the packet switching unit of a system control board. Therefore, double backplane bandwidth resources of the system control board are consumed. Local: intra-board Native E-Line services are directly forwarded by the switching units of the board. However, this will restrict the functions of some packet switching units that depend on system control boards. The restrictions include: Intra-board Native E-Line services do not support the LM function of ETH-OAM. Therefore, the packet loss rate of the Native E-Line services could not be tested using meter-free tests. The source and sink ports of intra-board Native E-Line services do not support the LAG function. If the source or sink ports are configured with the LAG function, the forwarding mode is automatically switched to centralized mode. Other types of Ethernet services on an EM6T, EM6TA, EM6F, or EM6FA board and all types of Ethernet services on other types of Ethernet boards are forwarded in centralized mode.

Ethernet Service Forward Mode

Local, Center

Default: Center

Indicates the Ethernet service forwarding mode of the NE. The options are as follows:

Center: intra-board Native E-Line services must be forwarded through the packet switching unit of a system control board. Therefore, double backplane bandwidth resources of the system control board are consumed.
Local: intra-board Native E-Line services are directly forwarded by the switching units of the board. However, this will restrict the functions of some packet switching units that depend on system control boards. The restrictions include:
- Intra-board Native E-Line services do not support the LM function of ETH-OAM. Therefore, the packet loss rate of the Native E-Line services could not be tested using meter-free tests.
- The source and sink ports of intra-board Native E-Line services do not support the LAG function. If the source or sink ports are configured with the LAG function, the forwarding mode is automatically switched to centralized mode.

Other types of Ethernet services on an EM6T, EM6TA, EM6F, or EM6FA board and all types of Ethernet services on other types of Ethernet boards are forwarded in centralized mode.
