Note: After making the changes on the Edit screen, you must click Apply on this screen for the changes to take effect. However, to not disrupt PTP service, you should make all changes first then click Apply only once. Each time you click Apply, the PTP card stops service for 30 seconds while it re-configures to its new settings. Click Refresh to update the display.
Each field of the module configuration screen is described in the table below.

Announce Msg Rate |
Indicates the PTP unicast Announce message rate, (2^y), in seconds. Range = -3 to 4. A value of -3, which means 8 per second. |
Delay Msg Rate |
Indicates the PTP unicast Delay message rate, (2^y), in seconds. Range = -7 to 7. A value of -6, which means 64 per second. |
PTP Port Attributes |
|
Clock ID |
The PTP Port Clock Identity (64-bit value). The format is 0Xaaaaaaaaaaaaaaaa. The “a” represents a hex value. The clockid format contains a prefix hex number token (0X) following up to 16 hex characters. |
Priority 1 |
Indicates the PTP Port Priority 1. Range = 0 to 255 |
Priority 2 |
Indicates the PTP Port Priority 2. Range = 0 to 255 |
Domain |
Indicates the PTP Domain. Range = 0 to 255 |
Time Scale |
Indicates the time scale, PTP or ARB (arbitrary) |
Max Clients |
Indicates the maximum
number of clients. Range =64 to 125
Note: SSU2000 6.2 can have up to 400 clients. |
PTP Unicast |
|
Max Dynamic Unicast Lease Interval |
Indicates the PTP maximum Dynamic Unicast Lease Interval. Range = 10 to 1000 seconds |
Negotiate State |
Indicates the PTP Unicast Negotiation state, Enabled or Disabled. |
Two Step State |
|
Two Step State |
Indicates whether the two-step clock operation is enabled. This panel is not displayed for legacy devices earlier than SSU 2000 6.3. |
PTP Profile |
|
Profile |
Identifies PTP profile to ITU_G8265_1 or TELCOM_2008 selection. This panel is not displayed for legacy devices earlier than SSU 2000 6.3. |
PTP SSM Option |
|
SSM Option |
This option is only available when PTP runs on ITU_G.8265.1. All the clock classes are defined according to the PQL (Priority Quality Level) value. Users are allowed to choose SSM Option 1 or Option 2 to determine the exact clock class. This panel is not displayed for legacy devices earlier than SSU 2000 6.3. |
