secondary	Unused front-panel secondary port dedicated to Hardware Assist.
loopback-port	Port to be configured as loopback.
port	Port number.
none	Unconfigures the port number and disables hardware assist if only the primary loopback port (or secondary loopback port) is configured.

None.

Usage Guidelines

The unused front panel port can be configured as a loopback port to enable BFD hardware assist mode. The primary or secondary loopback port must be configured for this feature. The loopback-port is not available for switching the user-data traffic, but is used internally by the BFD hardware to send control packets. This port must not be part of any This command is available on the ExtremeSwitching X440-G2, X450-G2, X460-G2, X465, X590, X620, X670-G2, X690, X695, X870, 5320, 5420, 5520 series switches. and should not be a trunk port. Use the none option to unconfigure the loopback port and disable hardware assist if only the primary loopback port (or secondary loopback port) is configured. Make sure that other applications have not already configured these ports as loopback ports. Use the show bfd command to view the configured loopback ports. Configuring "not-present" ports as loop-back ports is not supported.

Example

The following command configures port 10 as the primary loopback port for the BFD hardware assist feature:

configure bfd hardware-assist primary loopback-port 10

The following command configures port 11 as secondary loopback port for BFD hardware assist feature:

configure bfd hardware-assist secondary loopback-port 11

The following command unconfigures the primary loopback port:

configure bfd hardware-assist primary loopback-port none

The following command unconfigures the secondary loopback port:

configure bfd hardware-assist secondary loopback-port none
