Port Clock
Figure 10-6 Advanced Config Page: Synchronization
– SyncE Port Clock
For Electrical 10/100/1000 ports (RJ45) the clock config can be set.
The port clock config is relevant only for SyncE configuration.
The Port Clock determines the clock flow direction (relevant only when carrying Sync E
over 1000BaseT).
When using fibers (SFP), SFPs clock is carried independently and the clock configuration
is not available.
The ports’ default is Auto (clock direction determined by the auto-neg protocol).
The relevant Ethernet standards define that two RJ45 ports connected between them
MUST be configured to one of the automatic modes (auto or synce) or should be
configured manually one to master and second to slave.
When using SyncE over RJ45, the Ethernet port’s Clock must be set manually as per one
of the following options:
1.
Option 1: Clock=synce. In this configuration, the clock direction is selected
automatically by the SyncE SSMs.
2.
Option 2: Clock=Master/Slave. Manually set Clock=Slave on the port that
receives the SyncE clock and Clock=Master on the port that transmits the SyncE
clock. This mode must be used when no SSMs are used on the network.
Configuring the port clock using the CLI:
set eth eth1 clock {auto | master | slave | synce}]
