Syntax Definitions
echo-only
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
Specifies asynchronous mode with the echo function disabled.
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
