Displaying And Maintaining Bfd - HP A5830 series Configuration Manual

To do...
•
Configure the minimum
interval for receiving BFD
control packets
• Configure the detection time
multiplier
In Figure 41
Min RX Interval as 300 milliseconds, and Detect Mult as 5 on Router A, and configure the Desired Min
TX Interval as 150 milliseconds, Required Min RX Interval as 400 milliseconds, and Detect Mult as 10 on
Router B,
The actual transmitting interval on Router A is 400 milliseconds, which is the greater value between
•
the minimum interval for transmitting BFD control packets on Router A (100 milliseconds) and the
minimum interval for receiving BFD control packets on Router B (400 milliseconds).
The actual transmitting interval on Router B is 300 milliseconds, which is the greater value between
•
the minimum interval for transmitting BFD control packets on Router B (150 milliseconds) and the
minimum interval for receiving BFD control packets on Router A (300 milliseconds).
The actual detection time on Router A is 3000 milliseconds, which is 10 × 300 milliseconds (Detect
•
Mult on Router B × actual transmitting interval on Router B).
The actual detection time on Router B is 2000 milliseconds, which is 5 × 400 milliseconds (Detect
•
Mult on Router A × actual transmitting interval on Router A).

Displaying and maintaining BFD

To do...
• Display information about
BFD-enabled interfaces
• Display information about
enabled BFD debugging
• Display BFD session
information
•
Clear BFD session statistics
Use the command...
bfd min-receive-interval value
bfd detect-multiplier value
for example, if you configure the Desired Min TX Interval as 100 milliseconds, Required
Use the command...
display bfd interface [ verbose ] [ | { begin | exclude
| include } regular-expression ]
display bfd debugging-switches [ | { begin | exclude
| include } regular-expression ]
display bfd session [ slot slot-number [ all | verbose ]
| verbose ] [ | { begin | exclude | include } regular-
expression ]
reset bfd session statistics [ slot slot-number ]
