Enabling Trap; Displaying And Maintaining Bfd - HPE FlexNetwork HSR6800 series Configuration Manual

•
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).
The tunnel interfaces of HSR6802/HSR6804/HSR6808 support BFD. If you do not specify a tunnel
template on the tunnel interface for receiving BFD packets with the service slot slot-number
command, the active main processing unit (MPU) of the device will receive and then discard BFD
packets, and the session state remains down. To avoid such cases, Hewlett Packard Enterprise
recommends specifying a tunnel template, rather than the active MPU, on the tunnel interface by
using the service slot slot-number command.

Enabling trap

When the trap function is enabled on the BFD module, the module will generate trap messages at
the notifications level to report the important events of the module. The generated trap messages are
sent to the device's information center, which determines the output rules for the trap messages
(whether to output the trap messages and the output destinations). For the information center
configuration, see Network Management and Monitoring Configuration Guide.
To enable BFD trap:
Step
1. Enter system view.
2. Enable BFD trap.
