What Cisco IOS XE command configures the domain value on the PTP?

  • ptp transport ipv4 udp
  • ptp vlan
  • ptp mode
  • ptp domain

Explanation: The ptp domain command is used in global configuration mode to define the domain value for the Precision Time Protocol (PTP). A PTP domain represents a logical grouping of clocks that synchronize with each other, allowing multiple independent clock distribution systems to share the same physical network medium.

By default, the PTP domain is set to 0, but the ptp domain command allows administrators to configure a specific value, typically within a range of 4 to 127. Other commands listed serve different functions: ptp mode selects the clock synchronization role (e.g., boundary or transparent), ptp vlan identifies the specific VLAN for PTP traffic on trunk ports, and ptp transport ipv4 udp specifies the Layer 3 transport method.
