The display bfd link-bundle session command displays information about BFD for link-bundle sessions.
The actual command output varies according to the device. The command output here is only an example.

| State | Current status of the BFD session. |
| WTR Interval (ms) | WTR time. |
| Total Up/Down Main Session Number | Number of main sessions. |
| Total Up/Down Sub Session Number | Number of sub-sessions. |
| Session Detect Mode | The value is Asynchronous Mode Without Echo Function. |
| Sub Session Count | Number of sub-sessions for the main session. |
| Sub Session Number | Name of the sub-session for the main session. |
| Name | Name of the BFD session. |
| Local Discriminator | Local discriminator of the BFD session. |
| Local Detect Multi | Configured local detection multiplier. |
| Remote Discriminator | Remote discriminator of the BFD session. |
| Detect Interval (ms) | Detection interval. |
| BFD Bind Type | Binding type of the BFD session. The local Layer 3 Eth-Trunk interface bound to the BFD for link-bundle session is displayed. |
