bfd min-transmit-interval

Syntax

bfd min-transmit-interval没有bfd min-transmit-interval

Description

Sets the minimum time interval between transmitted BFD control packets on an interface.

The没有form of this command sets the minimum interval between transmitted BFD control packets to the default value of 3000 ms.

Command context

config-if

Parameters

Specifies the minimum transmit interval in milliseconds. Range:500 to 20000 (6300, 6400, 8360, 8400).50 to 20000 (8320, 8325). Default: 3000.

Authority

Administrators or local user group members with execution rights for this command.

Usage

  • If the minimum time interval is set between 500 ms and 1000 ms, thenbfd detect-multipliermust be set to at least 3.
  • Ifbfd detect-multiplieris set to 1, then the minimum transmit interval must be set to at least 3000 ms.
  • Whenever the minimum time interval is set to a value less than 1000 ms, BFD automatically adjusts the transmission interval to 1000 ms if any of the following conditions apply:

    • The session is operating in asynchronous mode and echo is enabled.

    • The session state is in any other state thanup.

    As described in RFC 5880, this behavior occurs because BFD echo provides quick detection which allows the BFD asynchronous session to lower its traffic/resource requirements.

Examples
