Usage Guidelines

Usage Scenario

On an NBMA network, to enable a device to send poll Hello packets at a specified interval after the device's neighbor goes Down, run the dcn ospf timer poll 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

The interval value specified in the dcn ospf timer poll command must be at least four times as long as interval specified in the dcn ospf timer hello command.

If the dcn ospf timer poll command is run in the interface view, the interval at which poll Hello packets are sent is set for DCN interface.
If the dcn ospf timer poll 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 poll Hello packets every 130 seconds.
