Configures gPTP Announce parameters on the specified ports. Announce messages are used to elect the grandmaster clock and determine the time-synchronous spanning tree.
| port_list | Specifies one or more of the switch's physical ports. |
| only | Apply change only to specified port, even if port is master of a load sharing group. |
| all | Specifies all of the switch's physical ports. |
| log_2_interval | The interval between Announce messages used by the switch on the port when the port is initialized or when the switch receives a message interval request TLV with announceInterval value 126. This value is in log 2 seconds. The valid range of values is -3 (2-3 = 0.125 seconds) to 17 (217 = 131072 seconds). |
| timeout_count | On a gPTP slave port, the number of announce intervals to wait without receiving an Announce message before assuming the master is no longer sending Announce messages. |
Use this command to configure gPTP Announce parameters on the specified ports. Announce messages are used to elect the grandmaster clock and determine the time-synchronous spanning tree. Announce selects the grandmaster in the network and establishes the tree from the grandmaster to all other time-aware systems in the network.
initial-interval corresponds to 802.1AS parameter initialLogAnnounceInterval.
receipt-timeout corresponds to 802.1AS parameter announceReceiptTimeout.

This command was first available in ExtremeXOS 15.3.
This command is available on Summit X450-G2, X460-G2, and X670-G2 switches if the AVB feature pack license is installed on the switch.
