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. 8. In the Announce Interval field, specify the desired 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. 9. Configure the SyncRx Timeout. This value sets the number of SYNC intervals that have to pass without receipt of SYNC information before considering that the master is no longer transmitting.. 10. Configure the AnnounceRx Timeout. This value sets the number of ANNOUNCE intervals that have to pass without receipt of ANNOUNCE PDU before considering that the master is no longer transmitting. 11. Click the Apply button.

The possible roles are as follows: • Disabled (default) • Master • Slave • Passive The mean propagation delay on the interface Indicates whether the interface is receiving PDELAY response messages from other end of the link. Indicates whether the interface is 802.1AS capable. By default, the interface is not 802.1AS capable. An estimated ratio of the frequency of the local clock entity of the time-aware system at the other end of the link attached to this port, to the frequency of the local clock entity of this time-aware system.

802.1AS port settings
Field
Description
Port Role
The 802.1AS role of the interface. The possible roles are as follows:
Disabled (default)
Master
Slave
Passive
Propagation Delay
The mean propagation delay on the interface
Measuring Pdelay
Indicates whether the interface is receiving PDELAY response
messages from other end of the link.
802.1AS Capable
Indicates whether the interface is 802.1AS capable. By default, the
interface is not 802.1AS capable.
Neighbor Rate Ratio
An estimated ratio of the frequency of the local clock entity of the
time-aware system at the other end of the link attached to this port, to
the frequency of the local clock entity of this time-aware system.
Current Sync Interval
The current mean time interval between successive SYNC messages
sent over a link, in logarithm to base 2 format.
