BFD for IPv6 interfaces is a demonstration feature on some products. For more information about feature support, see Fabric Engine Feature Support Matrix.

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

  1. In the navigation pane, expand Configuration > Edit.
  2. Select BFD.
  3. Select the Sessions tab.
  4. Optional: Select Filter.
  5. Optional: Select AddrType.
  6. Optional: In the AddrType field, specify a value for address type.

BFD Sessions Field Descriptions

Use the data in the following table to use the Sessions tab.

Name Description

Discriminator

Specifies the local discriminator that uniquely identifies the BFD session.

DesiredMinTxInterval

Specifies the preferred minimum interval for transmitting BFD control packets by the local system.

ReqMinTxInterval

Specifies the minimum interval for transmitting BFD control packets that the local system can support.

DestAddr

Specifies the destination IP address of the interface associated with the BFD session.

OldState

Specifies the old state of the BFD session.

App

Specifies the applications configured on the BFD session.
