About this task
BFD provides a failure-detection mechanism between two systems. Use the following procedure to display information about BFD sessions. You can optionally display BFD session information for IPv4 or IPv6 interfaces.
Procedure
- In the navigation pane, expand .
- Select BFD.
- Select the Sessions tab.
- Optional: Select Filter.
- Optional: Select AddrType.
- Optional: In the AddrType field, specify a value for address type.
