SR6604-X/SR6608-X/SR6616-X
Yes
To use a ToD clock, you must configure ToD input or output:
•
ToD input
—The device obtains clock signals from an external ToD clock and synchronizes ToD to all
devices in the PTP network.
•
ToD output
—The device operates as a ToD clock to synchronize ToD to other devices.
To implement more accurate time synchronization, you can specify a delay correction value.
To configure ToD input or output:
Step Command
Remarks
1.
Enter system view.

Configure ToD input or output.
ptp
{
tod0
|
tod1
} {
input
[
delay
input-delay-time
] |
output
[

output-delay-time
] }
By default:
•
The device receives signals
from an external ToD clock.
•
The delay correction value for a
ToD clock is 0 nanoseconds.
