Usage Guidelines

Usage Scenario

To set the interval at which DCN serial interfaces or sub-interfaces 4094 send hello packets, run the dcn ospf timer hello command.

Prerequisites

The DCN feature has been enabled globally using the dcn (interface view) command in the interface view, or DCN communication through sub-interfaces 4094 has been enabled using the dcn mode vlan command in the GE interface view.

Precautions

If the dcn ospf timer hello command is run in the interface view, the hello packet sending interval is set for DCN interface.

If the dcn ospf timer hello command is run in both the interface and DCN views, only the configuration in the interface view takes effect.

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

Example

# Configure the DCN serial interfaces of GE 0/1/0 to send Hello packets every 20 seconds.
