Adds an entry to the unicast master table for a PTP clock instance. This command is available for boundary and ordinary clocks.
| boundary | Boundary clock. |
| ordinary | Ordinary clock. |
| add unicast-master | IP addresses that are potential master to the local clock. |
| ipv4_address | IPv4 address. |
| query-interval | Mean interval between requests from a node for a unicast Announce message |
| seconds_log_base_2 | The log base 2 value in seconds of the mean interval between requests from a node for a unicast Announce message. For example, to specify 8 seconds between requests, use 3. The default value is 1, and the range is -2 to 4. |
| vlan_name | This command is available on the ExtremeSwitching X440-G2, X450-G2, X460-G2, X465, X590, X620, X670-G2, X690, X695, X870, 5320, 5420, 5520 series switches. name to which the command is to be applied. |
The default value of the query interval is log base 2 (1), or 2 seconds mean interval between requests from the node for a unicast Announce Message.
Use this command to add an entry to the unicast master table for a PTP clock instance. This command is available only for boundary clocks. The mean interval between requests from the node for a unicast Announce message can be configured from 1/4 second to 16 seconds, with a default of 2 seconds.
The following command adds a static unicast master entry to the PTP clock port lpbk-gm in the boundary clock:
# configure network-clock ptp boundary add unicast-master 192.168.1.1 query-interval 0 vlan lpbk-gm
The following command adds a static unicast master entry to the PTP clock port lpbk-master in the ordinary clock clock:
# configure network-clock ptp ordinary add unicast-master 192.168.15.10 vlan lpbk-master
This command was first available in ExtremeXOS 15.1.
This command is available on ExtremeSwitching X670-G2, and X460-G2 series switches.
Note
PTP commands can be used only with the Network Timing feature pack.
