Ethernet Distributed Link Aggregation Management

With the Ethernet cross-board link aggregation group (LAG), the Ethernet ports on two Ethernet boards are configured as a port aggregation group to establish links with an opposite NE. In this way, the Ethernet link protection is realized.The DLAG protection can work with the SW SNCP protection. Two independent electrical cross-connections must be configured between the main board of the DLAG protection and the working and the protection board of the SW SNCP protection respectively.

Navigation Path

In the NE Explorer, select the NE and choose Configuration > Ethernet Distributed Link Aggregation Management from the Function Tree.

NOTICE:

The DLAG protection cannot co-exist with the following functions or protection:

BPS protection
DBPS protection
Client-side 1+1 protection
LPT function
LAG function

In terms of configuring the DLAG services of the TBE board, note the following rules.

Other than the general configuration of dual fed and selective receiving function, the Ethernet interface attributes and Ethernet private line services need to be configured. (For how to configure the Ethernet interface attributes and Ethernet private line services, refer to Configuration Guide.)
The client-side service attributes (for example, working mode of the Ethernet) of the corresponding channels of active and standby boards must be the same.

Parameters

Field	Value	Description
LAG No.	1 to 64	Displays the LAG No.
LAG Name	For example, DLAG1	Displays the name of an LAG.
Load Sharing	Non-Sharing	Currently only non-sharing is supported.
Master Board	Equipment that supports the master and slave shelf management: shelf ID(shelf name)-slot number-board name Equipment that does not support the master and slave shelf management: slot number-board name	Displays the active board of an LAG.
Master Port	For example, PORT3	Displays the active port of an LAG.
Standby Board	Equipment that supports the master and slave shelf management: shelf ID(shelf name)-slot number-board name Equipment that does not support the master and slave shelf management: slot number-board name	Displays the standby board of an LAG.
Standby Port	For example, PORT3	Displays the standby port of an LAG.
Revertive Mode	Revertive, Non-Revertive Default: Revertive	The Revertive Mode (DLAG) parameter specifies whether to switch a service back to the main port that recovers from a fault.
LAG Status	For example, active	Displays the current status of an LAG.
Active Board	Equipment that supports the master and slave shelf management: shelf ID(shelf name)-slot number-board name Equipment that does not support the master and slave shelf management: slot number-board name	Displays the current working board of an LAG.
Active Port	For example, PORT3	Displays the current working port of an LAG.
LAG Priority	0 to 65535	Displays the priority of an LAG.
Master Port Priority	0-65535 Default: 32768	The Master Port Priority (DLAG) parameter specifies the priority of the main port in a distributed link aggregation group (DLAG). A port of higher priority is preferred to carry the services.
Standby Port Priority	0-65535 Default: 32768	The Standby Port Priority (DLAG) parameter specifies the priority of the Standby port in a DLAG. The priority is specified in the LACP. A port of higher priority is preferred to carry the services.
