port
Syntax port port-id [create]
no port port-id
Context config>system>ptp>clock
Description This command configures PTP over Ethernet on the physical port, so that PTP messages are
sent and received over the port using Ethernet encapsulation. There are two reserved
multicast addresses allocated for PTP messages (see Annex F of IEEE Std 1588- 2008 and
the address command). Either address can be configured for the PTP messages sent
through this port.
The adapter card, module, or fixed platform containing the specified port cannot be
deprovisioned while the port is configured for PTP. A port configured for dot1q or qinq
encapsulation can be configured as the physical port for PTP over Ethernet. The
encapsulation type and the Ethernet port type cannot be changed when PTP Ethernet
multicast operation is configured on the port.
This command is only available when the clock-id parameter is defined as csm.
Default n/a
Parameters port-id — specifies the physical port in the format slot/mda/port
address
Syntax address {01:1b:19:00:00:00 | 01:80:c2:00:00:0e}
no address
Context config>system>ptp>clock>port
Description This command configures the MAC address to be used as the multicast destination MAC
address for transmitted PTP messages. The IEEE Std 1588-2008 Annex F defines the two
reserved addresses for PTP messages as:
• 01-1B-19-00-00-00 for all messages except peer delay messages
• 01-80-C2-00-00-0E for peer delay messages
The system will accept PTP messages received using either destination MAC address,
regardless of the address configured by this command.
The no form of this command returns the address to the default value.
Default 01:1b:19:00:00:00
