The value of tmnxOamBfdOnLspOperState indicates the operational state (with respect to the RFC 5884 LSP Ping procedures) of the BFD-on-LSP session identified by tmnxOamBfdOnLspLocalBfdDiscrim. Code Points 'bootstrapInProg(1)' - the session is being bootstrapped using LSP ping, as described in RFC 5884 Section 6. 'bootstrappedNoPeriodicVerif(2)' - the bootstrap completed successfully. This is the success state for a session which has periodic verification of the LSP (using LSP ping) disabled. Periodic verification is disabled by setting the session's LSP ping interval (e.g. TIMETRA-LDP-NG-MIB::vRtrLdpNgBfdOnLspPfxListPingIntv) to zero. 'bootstrappedSendingPeriodicVerif(3)' - the bootstrap completed successfully, and the session is sending LSP pings to periodically verify the LSP (as described in RFC 5884 Section 3.2). This is the success state for a session which has periodic verification of the session enabled. The BFD-level operational state of a BFD-on-LSP session is given by TIMETRA-BFD-MIB::tmnxBfdOnLspSessOperState.
