BFD 5Clearing BFD neighbor sessionsYou can clear all BFD neighbor sessions or a specified BFD neighbor session using the followingcommand.clear bfd neighborSyntax: clear bfd neighbor [ | ]• - Specifies the IPv4 address of a neighbor whose BFD session you want to clear.• - Specifies the IPv6 address of a neighbor whose BFD session you want toclear.Executing this command without specifying an IPv4 or IPv6 address clears the sessions of all BFDneighbors.BFD debug commandsThis section describes how to use diagnostic debug commands to monitor BFD environments.debug bfdSyntax: [no] debug bfd [application | hitless-upgrade | ipc-error | ipc-event | itc | pbif | timer]• application - Displays information about BFD applications.• hitless-upgrade - Displays information about hitless upgrade events.• ipc-error - Displays information about interprocess communication (IPC) errors.• ipc-event - Displays information about IPC events.• itc - Displays information about BFD inter-task communication (ITC) activity.• pbif - Enables debugging of BFD use of Peripheral Bus Interface FPGA (PBIF) Assist.• timer - Enables debugging of BFD timer operation on LP.debug bfd applicationSyntax: [no] debug bfd applicationThis command generates information about BFD application activity. When this command isenabled, output resembles the following example, which shows that the OSPF application wasdisabled, and then enabled.Brocade# debug bfd applicationapplication: debugging is onBFD/APP: Application: AppId: ospf App Subid: 0 DeRegistered with BFDBFD/APP: Application: AppId: ospf App Subid: 0 Registered with BFDdebug bfd hitless-upgradeSyntax: [no] debug bfd hitless-upgradeThis command displays information about BFD hitless upgrade events, as shown in the followingexample.Brocade MLX Series and Brocade NetIron XMR Diagnostic Guide 10953-1002426-02
