8. From the Admin Mode menu, select Enable or Disable.
For the 802.1AS settings to take effect on the interface, select Enable. The default
is Disable.
9. In the Pdelay Threshold field, specify the propagation delay threshold for the
interface.
The threshold determines whether the port is capable of participating in the 802.1AS
protocol. If the propagation delay on the interface is above the threshold you
configure, the interface is not considered capable of participating in the 802.1AS
protocol. The peer delay must be less than the threshold value configured on the
interface. The range is from 0 to 1,000,000,000 nanoseconds (ns). The default is
2500 ns.
10. In the Allowed Lost Responses field, specify the allowed loss response value.
If the interface does not receive valid responses to PDELAY_REQ messages above
the value of the allowed lost responses, a port is considered to not be exchanging
peer delay messages with its neighbor. The range is from 0 to 65,535. The default
is 3.
11. In the Initial Sync Interval field, specify the transmission rate of SYNC messages.
This value is the logarithm to the base 2 of the mean-time interval between successive
SYNC messages sent on this interface. The configured initial interval becomes the
current interval only after the port is initialized or re-initialized for 802.1AS operation.
The range is from –5 to 5. The default is –3.
12. In the Initial Pdelay Interval field, specify the transmission rate of PDELAY_REQ
messages.
This value is the logarithm to the base 2 of the mean time interval between successive
PDELAY_REQ messages sent on this interface. The configured initial interval becomes
the current interval only after the port is initialized or re-initialized for 802.1AS
operation. The range is from –5 to 5. The default is –3.
13. In the Initial Announce Interval field, specify the transmission rate of ANNOUNCE
messages.
This value is the logarithm to the base 2 of the mean time interval between successive
ANNOUNCE messages sent on this interface. The configured initial interval becomes
the current interval only after the port is initialized or re-initialized for 802.1AS
operation. The range is from –5 to 5. The default is –3.
14. In the SyncRx Timeout field, specify the number of SYNC intervals.
This value sets the number of SYNC intervals that must pass without receipt of SYNC
information before the switch detects that the master clock is no longer transmitting.
15. n the AnnounceRx Timeout field, specify the number of ANNOUNCE intervals.
