Hi, I found the BFD tx time is not correct.
vpp# show bfd sessions
Index Property Local value Remote value
0 IPv4 address 2.2.2.4 2.2.2.3
Session state Down Down
Diagnostic code No Diagnostic No Diagnostic
Detect multiplier 4 0
Required Min Rx Interval (usec) 3000000 1
Desired Min Tx Interval (usec) 2000000 0
Transmit interval 1000000
Last control frame tx 24456.97s ago
-------------------------------this time is wrong.
Min Echo Rx Interval (usec) 1 0
Demand mode no no
Poll state BFD_POLL_NOT_NEEDED
Number of configured BFD sessions: 1
I check the code found the get time API is not correct.
static u8 *
format_bfd_session_cli (u8 * s, va_list * args)
{
....
u64 now = clib_cpu_time_now (); --------------- this line , I think it should
be "vlib_time_now (vm)"
tmp = format (tmp, "%.2fs ago", (now - bs->last_tx_nsec) *
-------------- bs->last_tx_nsec is got by 'vlib_time_now'
91 vm->clib_time.seconds_per_clock);
92 s = format (s, "%10s %-32s %20v\n", "", "Last control frame tx", tmp);
