Specifies echo only mode.

demand echo enable

Specifies demand mode with the echo function enabled.

demand echo disable

Specifies demand mode with the echo function disabled.

asynchronous echo enable

Specifies asynchronous mode with the echo function enabled.

asynchronous echo disable

Defaults

By default, BFD is set to globally operate in demand mode with the echo function enabled.

Platforms Supported

OmniSwitch 6400, 6850, 6855, 9000, 9000E

Usage Guidelines

• The global operational mode and echo status is also configurable at the BFD interface level. Note that

configuring the global value with the ip bfd-std mode command does not override the value set for the
interface using the ip bfd-std interface mode command.

• The global operational mode and echo status serves as the default mode and status for a BFD interface.

The default mode and status is overridden when a specific value is configured for the interface.

Examples

-> ip bfd-std mode echo-only

-> ip bfd-std mode demand echo enable
