Synchronizing the System Time of the
96
7.3 Precison Time Protocol
Layer 2 Enhanced with Layer 2 Professional
Release 1.0 10/05
PTP SyncLowerBound
: Lower PTP synchronization threshold =
difference between reference time and local time, entry in
nanoseconds. If the difference between the local clock and the
reference clock exceeds the value for the lower PTP synchroni-
zation threshold, the local clock is considered to be synchronous
with the reference clock.
PTP SyncUpperBound
: Upper PTP synchronization threshold =
difference between the reference time and local time, entry in
nanoseconds. If the difference between the local clock and the
reference clock exceeds the value for the upper PTP synchroni-
zation threshold, the local clock is considered to be synchronous
with the reference clock.
PTP SubdomainName
: Name of the PTP subdomain which the
local clock belongs to. By selecting “Reinitialize”, you accept the
changes.
PTP PreferredMaster
: Defines the local clock as the Prefer-
red Master.
D
Status (display)
PTP is Synchronized
: The local clock runs synchronously
with the reference clock, compare
PTP SyncLowerBound
and
PTP SyncUpperBound
.
PTP OffsetFromMaster
: Amount of deviation between the
local time and the reference clock in nanoseconds.
PTP AbsMaxOffset
: Amount of maximum deviation between
the local clock and the reference clock in nanoseconds since the
local clock was last reinitialized. To reinitialize the local clock,
select “ReInitialize” in this dialog or else reset the Switch.
PTP OneWayDelay
: Simple signal runtime between the local
Switch and the reference clock in nanoseconds.
PTP GrandmasterUUID
: MAC address of the grandmaster
clock (Unique Universal Identifier).
PTP ParentUUID
: MAC address of the master clock with which
the local time is synchronized.
