The bfd-detect command enables dynamic BFD for PW in a PW template and adjusts the sending interval, receiving interval, and local detection multiplier of BFD detection packet.
The undo bfd-detect command restores the default configuration.
By default, dynamic BFD for PW is not enabled in a PW template.

Parameter |
Description |
Value |
|---|---|---|
min-tx-interval tx-interval |
Specifies the interval at which BFD packets are sent. |
The value ranges from 100 to 1000, in milliseconds. By default, the value is 1000. After the set service-mode enhanced command is configured on the S5720-HI, S5731-H, S5731S-H, S5730-HI, and S6720-HI, the value ranges from 3 to 1000. After the set service-mode enhanced-bfd command is configured on the S5732-H, S6730S-H, and S6730-H, the value ranges from 3 to 1000. |
min-rx-interval rx-interval |
Specifies the interval at which BFD packets are received. |
The value ranges from 100 to 1000, in milliseconds. By default, the value is 1000. After the set service-mode enhanced command is configured on the S5720-HI, S5731-H, S5731S-H, S5730-HI, and S6720-HI, the value ranges from 3 to 1000. After the set service-mode enhanced-bfd command is configured on the S5732-H, S6730S-H, and S6730-H, the value ranges from 3 to 1000. |
detect-multiplier multiplier |
Specifies the local detection multiplier value of a BFD session. |
An integer ranging from 3 to 50. The value is 3 by default. |
If the BFD session is found to be Down, the system automatically adjusts the receiving interval and sending interval of the local end to a random value ranging from 1000 ms to 3000 ms to reduce system resource utilization. When the BFD session restores the Up state, the user-defined interval is used again.
