Predefined user roles network-admin Parameters value: Specifies a single-hop detection time multiplier in the range of 3 to 50. Usage guidelines The detection time multiplier determines the maximum number of concurrent BFD packets (including control packets and echo packets) that can be discarded. Table 30 Detection interval calculation method Mode Detection interval Echo packet mode Detection time multiplier of the sender × actual packet sending interval of the sender Control packet mode BFD session in Detection time multiplier of the receiver × actual asynchronous mode packet sending interval of the receiver Control packet mode BFD session in demand Detection time multiplier of the sender × actual mode packet sending interval of the sender Examples # Configure the single-hop detection time multiplier as 6 on VLAN-interface 11. system-view [Sysname] interface vlan-interface 11 [Sysname-Vlan-interface11] bfd detect-multiplier 6 bfd echo enable Use bfd echo enable to enable the echo packet mode. Use undo bfd echo enable to restore the default. Syntax bfd echo enable undo bfd echo enable Default The echo packet mode is disabled. Views Interface view Predefined user roles network-admin Usage guidelines If you enable the echo packet mode for a BFD session in which control packets are sent and the session comes up, BFD periodically sends echo packets to detect link connectivity and decreases the control packet receiving rate at the same time. 102
