 802.1AS Port Settings.

Select the ports to configure.

For information about how to select and configure one or more ports, see 

From the Admin Mode list, select Enable.

In the Pdelay Threshold field, specify the propagation delay threshold on 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 default value 
is 2500 nanoseconds. The range is 0–1,000,000,000 ns.

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.

In the Initial Sync Interval field, specify the desired 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.

In the Pdelay Interval field, specify the desired 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.
