PurposeCommand or Action
The switch uses this value to
determine whether the source clock
is traceable. If the clock class value
from all the peers is higher than the
clock class threshold value, the
BMCA may change all the port state
to listening.
Note
Specify the values for domain and clock
accuracy threshold
switch(config) # [no] ptp domain value
clock-accuracy-threshold value
Step 6
The range for the domain value is from 0 to
127.
The range for the clock-accuracy-threshold
value is from 0 to 255.

Example
The following example displays the PTP clock information:
switch(config-if)# show ptp clock
PTP Device Type: Boundary clock

Clock Domain: 5
Number of PTP ports: 2
Priority1 : 129
Priority2 : 255
Clock Quality:
Class : 248
Accuracy : 254
Offset (log variance) : 65535
Offset From Master : 0
Mean Path Delay : 391
Steps removed : 1

switch(config-if)#
Configuring PTP Cost Interface
You can configure interface cost on each PTP enabled port on a Cisco Nexus 3500 switch. The cost applies
to each PTP enabled port if the switch has more than one path to grandmaster clock.
