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.
client-timeout Sets the client timeout value. If less than several hundred
delay request messages have been received from a client
before the specified client timeout value, the Grandmaster
removes that client from the client list. If delay requests are
sent at a slow rate, then the client-timeout value must be
increased.
Applies to Default (Multicast) ptp profile.
announce-receipt-timeout Sets the announce timeout value for Multicast. This should
be set to a consistent value in the PTP domain.
vlanid Sets the VLAN ID for the Grandmaster in Multicast (default)
profile. A VLAN ID of 0 is used to specify that no VLAN is
being used. Only one VLAN will be supported in this
profiles.

how often to send announce messages to clients on the
specified port. Applies to Default (Multicast) PTP profiles

Grandmaster, how often to send synchronization messages
to clients on the specified port. Applies to Default (Multicast)
PTP profiles.
