Adjusting the BFD Detection Time
Context
When you set up a BFD session, you can adjust the minimum interval for sending BFD packets, minimum interval for receiving BFD packets, and local detection multiplier based on the network situation and performance requirements.
To reduce usage of system resources, when a BFD session is detected in Down state, the system adjusts the minimum interval for receiving BFD packets and the minimum interval for sending BFD packets to random values greater than 1000 ms. When the BFD session becomes Up, the configured intervals are restored.
Procedure
- Run system-view
The system view is displayed.
- Run bfd session-name
The BFD session view is displayed.
- Run min-tx-interval interval
The minimum interval for sending BFD packets is set.
By default, the minimum interval for sending BFD packets is 1000 ms.
- Run min-rx-interval interval
The minimum interval for receiving BFD packets is set.

When the BFD session becomes Up, the configured intervals are restored.
By default, the minimum interval for receiving BFD packets is 1000 ms.
- Run detect-multiplier multiplier
The local detection multiplier is set.
By default, the local detection multiplier is 3.
