Reference in use: Slave of 10.216.118.86
NetRef State: Maintain (last adj -0.217 ppm)
NetRef Masters:
10.216.118.73 Priority 1

10.216.118.90 Priority 3
10.216.118.88 Priority 4
Table 58 on page 144 describes the fields corresponding to the configured NetRef
nodes and synchronization details displayed in the output.

Field DescriptionField Name
Displays the IP address of the NetRef master node that is being referenced and used by the slave or
backup node.
Reference in use
Displays the NetRef state, such as Maintain, Aggressive, Starvation, or Wait. Also, this field displays
the number of packets per minute, which when reached, causes the clocking algorithm to change,
and which constrains the frequency adjustments to the adaptive clock.
If all the four master nodes goes down, the NetRef state remains in Starvation state and no switching
will take place. When the NetRef state of the slave node is Maintain and the primary master goes
down, the slave node is unable to receive the packets within the last 20 seconds. Therefore, the NetRef
state of the slave node moves from Maintain state to Starvation state and switching takes place.
When the NetRef state of the slave node is Aggressive and the primary master goes down, the slave
node is unable to receive the packets within the last 20 seconds. Therefore, the NetRef state of the
slave node transitions from Aggressive state to Starvation state and switching will take place.
