  • Devices support external time source backup if BITS1 ports on the active and standby MPUs are connected to the same time source.
  • Ports that do not have 1588v2 enabled transparently forward received MAC-encapsulated 1588v2 packets.
  • For the CE12800E, the ports obtained after port splitting do not support 1588v2.
  • When a CE12800E equipped with ED-E/EG-E/EGA-E series cards is upgraded from V200R005C00 to V200R005C10 or a later version, the existing 1588v2 configuration is not affected, but the 1588v2 configuration cannot be added or modified.
