TimeProvider 2300/2700 CLI Command Set
dscp
The Differentiated Services Code Point is an 6-bit field in
the 8-bit Differentiated Services (DS) field of the IP packet
header to specify what classes of traffic will be provided,
what guarantees are needed for each class, and how
much data will be sent for each class. When used with the
TP 2300/2700, it provides a way to prioritize packets for
PTP traffic.
dither
This is an advanced feature in which an intentionally
applied form of noise is used to randomize quantization
error, and thus to break up any undesirable synchronizing
effects with the network. With dither enabled, the TP
2300/2700 varies the T1 timestamp by a pseudo-random
sequence with peak variations of no more than +/- 800
sec.
announce-limit
Use to limit the minimum interval between announcements
(maximum rate) from the specified TP 2300/2700. This is a
way to restrict how network resources will be utilized.
The interval is 2
z
seconds, where z=
<announce-limit-value>.
sync-limit
Use to limit the minimum interval between synchronization
messages (maximum rate) from the specified TP
2300/2700 port. This is a way to restrict how network
resources will be utilized.
The interval is 2
z
seconds, where z= <sync-limit-value>.
delay-limit
Use to limit the minimum interval between between delay
requests for the specified TP 2300/2700 port. This is a way
to restrict how network resources will be utilized.
The interval is 2
z
seconds, where z= <delay-limit-value>.
unicast-negotiation
Use to enable or disable the Grandmaster’s ability to
dynamically negotiate with clients for service in Unicast
mode.
lease-limit
Sets the maximum duration of the lease for clients that
have dynamically negotiated for service in Unicast mode.
