Release Information Statement introduced in Junos OS Release 12.1.
Statement introduced in Junos OS Release 12.2 for ACX Series Routers.
Description Configure the quality level for the timing source so that the router knows the best available
source with which to synchronize. The quality level specifies the accuracy level of the
clock.
Options prc—Timing quality of a primary reference clock (option-1 only).
prs—Clock traceable to a primary reference source (option-2 only).
sec—Timing quality of an SDH equipment clock (option-1 only).
smc— Clock traceable to a self-timed SONET (option-2 only).
ssu-a—Timing quality of a type I or IV slave clock (option-1 only).
ssu-b—Timing quality of a type VI slave clock (option-1 only).
st2—Clock traceable to Stratum 2 (option-2 only).
st3—Clock traceable to Stratum 3 (option-2 only).
st3e—Clock traceable to Stratum 3E (option-2 only).
st4—Clock traceable to Stratum 4 free-run (option-2 only).
stu—Clock traceable to an unknown quality (option-2 only).
tnc—Clock traceable to a transit node clock (option-2 only).
