Issue Description
when configuring the 1588 v2 ACR in CX600 (version V600R003), the device cannot work as ACR server, the topology is as follow:

the ptp-adpatative is configured between UPE1 (CX600-X8) as client and PE-AGG1 (CX600-X8) as server.

Handling Process
by changing the slot mode to PTP mode. the problem was sloved and the negotiation state become success.

[PE-AGG1]set service-mode slot 8 PTP-1-MODE

Root Cause
first, we checked the connectivity between the 2 devices and we found that's it's OK. after that, we looked in the PTP configuration and it was right.
by checking the working mode of slot, we found that the slot working mode is NetStream mode, so the slot cannot work as ACR server in this mode. To overcome this issue, the working mode of the slot must be changed to the PTP mode.
