Description This command disables or enables a specific PTP peer. Shutting down a peer sends cancel
unicast negotiation messages on any established unicast sessions. When the peer is shut
down, all received packets from the peer are ignored.
If the clock-type is ordinary slave or boundary, and PTP is not shut down, the last enabled
peer cannot be shut down. This prevents the user from having PTP enabled without any peer
configured and enabled.

Description This command configures PTP over Ethernet on the physical port. The PTP process
transmits and receives PTP messages through the port using Ethernet encapsulation (as
opposed to UDP/IPv4 encapsulation).
The frames are transmitted with no VLAN tags even if the port is configured for dot1q or qinq
modes for encap-type. In addition, the received frames from the external PTP clock must
also be untagged.
There are two reserved multicast addresses allocated for PTP messages, as defined in IEEE
1588-2008 Annex F (see the address command for more information). Either address can be
configured for the PTP messages sent through this port.
This command applies only if the PTP profile is set to g8275dot1-2014.
Changing the encapsulation or the port type of the Ethernet port is not permitted when PTP
Ethernet multicast operation is configured on the port. To change the encapsulation or port
type, the physical port must be shut down.
The no form of this command deletes the specified PTP port.
