Restrictions
IEEE 1588 end-to-end transparent mode cannot be enabled when there are flexible modules or transceiver ports in the system that do not support IEEE 1588. If a user attempts this, an error message like the following displays:
Port A1 does not support IEEE 1588 end-to-end transparent mode.
Use the commandshow ptp
to identify the unsupported ports.IEEE 1588 end-to-end transparent mode cannot be enabled on a stack. If the user attempts this, an error message like the following displays:
IEEE 1588 end-to-end transparent mode cannot be enabled when stacking is enabled.
IEEE 1588 end-to-end transparent mode must be enabled or disabled on all ports at the same time.
MACsec cannot be enabled when IEEE 1588 end-to-end transparent mode is enabled.
