1.4.5 Checking the Configuration

After the configuration of detecting a static LSP through a static BFD session, you can view the
BFD configuration, BFD session information, BFD statistics, and the status of the static LSP.
Prerequisite
The configurations of the static BFD for static LSP function are complete.

For example, assume that the values of parameters are as follows:
l On the local device, the interval for sending BFD packets is set to 200 ms, the interval
for receiving BFD packets is set to 300 ms, and the detection multiple is set to 4.
l On the peer device, the interval for sending BFD packets is 100 ms, the interval for
receiving BFD packets is 600 ms, and the detection multiple is 5.
Then,
l On the local device, the actual interval for sending BFD packets is 600 ms calculated
by using the formula max {200 ms, 600 ms}, the interval for receiving BFD packets is
300 ms calculated by using the formula max {100 ms, 300 ms}, and the detection period
is 1500 ms calculated by 300 ms multiplied by 5.
l On the peer device, the actual interval for sending local BFD packets is 300 ms obtained
by using the formula max {100 ms, 300 ms}, the interval for receiving BFD packets is
600 ms obtained by using the formula max {200 ms, 600 ms}, and the detection period
is 2400 ms obtained by 600 ms multiplied by 4.
Run the mpls bfd min-rx-interval interval command to adjust the minimum interval for
receiving BFD packets.
The minimum interval for receiving BFD packets is adjusted on the local device.
When the device is equipped with an FSU, by default, the value is 10 milliseconds;
otherwise, by default, the value is 1000 milliseconds.
If the backward link is an IP link, this parameter is not applicable.
Run the mpls bfd detect-multiplier multiplier command to adjust the local BFD detection
multiple.
The default value is 3.
Run the quit command to return to the system view.
Run the bfdcfg-name command to enter the BFD session view.
Run the display bfd configuration { all | static }command to check the BFD configuration.
Run the display bfd session { all | static } command to check information about the BFD
session.
