This command enables or disables the IEEE 1588 Precision Timing Protocol on the system.

This protocol must be enabled on the system if clock synchronization across the network is required for circuit emulation or if the application requires access to a high quality clock, and one is not physically available.

From the Global Config Mode at both the Remote end and Hub end, enter ptp-1588-protocol.

Configure the specified ptp-1588 mode, master or slave, on the system.. The ptp-1588 mode {master | slave} command specifies the mode. The master mode must be enabled on the system that has access to a high-precision clock. The 1588 component derives timing from the system clock that is configured in "timing-source system" command. The slave mode should be used on a remote system that does not have access to high-precision clock source.

From the Global Config Mode at the Hub end, enter ptp-1588 mode master.

From the Global Config Mode at the Remote end, enter ptp-1588 mode slave.

The primary and backup ports for 1588 must be configured to participate in the vlanid specified in the command. This was configured earlier using the command vlan participation. When this command is not specified, 1588 traffic is sent untagged.

Specify the VLAN id over which the 1588 protocol packets are transmitted.

From the Global Config Mode at both the Remote and Hub end, enter ptp-1588 vlan <vlan id>, where vlan-id is in the range 1-3965.

Example: ptp-1588 vlan 10.

Specify the port(s) over which 1588 protocol packets are transmitted and received. There are 2 ports specified for the 1588 packet transmission/reception. These are the Primary and Backup ports. When the primary port fails, the packets are transmitted/received on the Backup port. When the Primary port recovers after a failure, the 1588 protocol packets transmission/reception is not reverted to the Primary port.

From the Global Config Mode at both the Remote and Hub end, enter ptp-1588 port primary <primary port> backup <backup port> where primary-port is the initial port used to send/receive 1588 packets and the backup port is the backup to send/receive packets. The ports are Ethernet ports in the range d{1-2}-{1-2}.

Example: ptp-1588 port primary d1-1 backup d1-1.

Important!

This is a mandatory parameter. It must be configured in both directions for the 1588 protocol messages to be exchanged. The primary-port and backup-port may be the same port.

Important!

Use this command only if two 1588 Masters are deployed at the Hub end. Use this command only on a system which runs the 1588 protocol in Master mode.

Use this command to specify the Priority1 or Priority2 parameter of the 1588 protocol. It is used only in the Master mode while sending the 1588 protocol messages. Change the default only if two 1588 Masters are deployed.

From the Global Config Mode at one of the Hub end nodes, enter ptp-1588 priority1 <priority> where priority is in the range of 0-255, default 255.

From the Global Config Mode at the other Hub end node, enter ptp-1588 priority2 <priority> where priority is in the range of 0-255, default 255.

Example: ptp-1588 priority1 200.

The following is a list of optional commands that may be performed at the Hub end. For more information on these commands, refer to the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Command Line Interface Guide.

• ptp-1588 domain <domain-number> — Specifies the PTP domain value of the 1588 protocol.

  Example: ptp-1588 domain 1

• ptp-1588 log-mean-sync-interval <mean-sync-interval-value> — Specifies the log-mean-sync-interval parameter of the 1588 protocol.

  Example: ptp-1588 log-mean-sync-interval 0

• ptp-1588 log-mean-announce-interval <interval> — Specifies the log-mean-announce-interval parameter of the 1588 protocol.

  Example: ptp-1588 log-mean-announce-interval 1.

• ptp-1588 multicast <MAC-address> — Specifies the Multicast MAC address on which to send the 1588 protocol messages.

The following is a list of optional commands that may be performed at the Remote end. For more information on these commands, refer to the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Command Line Interface Guide.

• ptp-1588 log-min-mean-delay-req-interval <interval> — Specifies the log-min-mean-delay-req-interval parameter of the 1588 protocol.

  Example: ptp-1588 log-min-mean-delay-req-interval 5

• ptp-1588 log-mean-announce-interval <interval> — Specifies the log-mean-announce-interval parameter of the 1588 protocol.

  Example: ptp-1588 log-mean-announce-interval 1

• ptp-1588 announce-receipt-timeout <timeout-value> — Specifies the announce-receipt-timeout parameter of the 1588 protocol.

  Example: ptp-1588 announce-receipt-timeout 2.

• ptp-1588 multicast <MAC-address> — Specifies the Multicast MAC address on which to listen for the 1588 protocol messages.
