AV Line of Fully Managed Switches M4250 Series Main User Manual 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.
