transparent-transmission interface

Function

The transparent-transmission interface command configures DCN packet transparent transmission entries on an interface.

The undo transparent-transmission interface command deletes DCN packet transparent transmission entries from an interface.

By default, DCN packet transparent transmission entries are not configured on an interface.

Format

transparent-transmission interface { interface-type1 interface-number1 | interface-name1 } to { interface-type2 interface-number2 | interface-name2 }

undo transparent-transmission interface { interface-type1 interface-number1 | interface-name1 } to { interface-type2 interface-number2 | interface-name2 }

Usage Guidelines

Usage Scenario

If a DCN has a large number of NEs, the DCN must be split. If a cross-ring gateway network element (GNE) is connected to rings where a large number of NEs exist, the rings are negatively affected, and services on the rings cannot be protected. In this case, you can configure DCN packet transparent transmission to protect the services.

This command is supported only in transport node.

Precautions

In VS mode, this command is supported only by the admin VS.

Transparent transmission must be configured before DCN is enabled on an interface.
The inbound and outbound interfaces in a transparent transmission interface pair can reside on different boards but must both be Ethernet interfaces.
If bidirectional transparent transmission is configured between interfaces 1 and 2, only one transparent transmission entry is generated regardless of which interface is configured first.
DCN supports a maximum of five transparent transmission entries.

Example

# Configure DCN packet cross-board transparent transmission.
