PurposeCommand or Action
Enabling PTP on the switch does not enable PTP
on each interface.
Note
Assigns 6 byte MAC address for PTP clock-identity. Default
clock identity is based on the MAC address of the switch.
switch(config-if) # ptp
clock-identity MAC Address
Step 3
The clock-identity is defined as per IEEE standard (MAC-48
Byte0 | MAC-48 Byte1 | MAC-48 Byte2 | FF | FE | MAC-48
Bytes3-5).
