ACX7024 Device GNSS Conguraon
SUMMARY
IN THIS SECTION
Congure GNSS Receiver | 12
The ACX7024 device supports the G.8275.1 prole, Telecom Grand Master (T-GM) me management funconality for
all devices on the network on 10G and 25G ports. Addionally, the system supports the following funconalies:
– Compliance to ITU-T G.8272 (Unied funconal architecture for transport networks) PRTC Class A.
– Support for mulple constellaons such as GPS, GLONAS, QZSS and Galileo.
– Support for mulpath spoong, jamming, interference detecon and isolaon mechanisms.
Use the following commands to congure the T-GM funconality:
– set chassis synchronization gnss-receiver
<(0|1)> receiver-type <name>
– set chassis synchronization gnss-receiver <(0|1)> interface
Use the following commands to enable GM funconality:
– set protocols ptp clock-mode ordinary
– set protocols ptp profile-type g.8275.1
– set protocols ptp master interface
<interface-name> multicast-mode transport ieee-802.3
– ptp-mode
– gnss-receiver
– show chassis synchronization gnss-receiver extensive
– show chassis synchronization extensive
– show ptp lock-status detail
In T-GM mode router funcons as an ordinary clock and all PTP congured ports are in "Master only" state. Up to 512
master ports are supported on ACX7024.
NOTE: A synchronous Ethernet (SyncE) input is not allowed when system is funconing as a T-GM. Use the
following command to congure a wait-to-restore check for SyncE input:
set chassis synchronization source interfaces et-0/0/4 quality-level prc wait-to-restore 0
