Explains how to implement Precision Time Protocol over Device Level Ring with transparent clock functionality and provides configuration guidance for VLAN changes in industrial network topologies.
Changing VLANs with PTP transparent clock
Describes the capability to change VLANs when using a Precision Time Protocol transparent clock, enabling redundant networks without time faults.
Precision time protocol over device level ring
Describes the integration of PTP and DLR that enables transparent clock VLAN changes on Device Level Ring networks.
How PTP over DLR works
Describes how PTP protocol synchronizes clocks over DLR networks using optimized grandmaster election and fault detection mechanisms.
PTP transparent clock
Describes a PTP clock mode that supports multiple VLANs on Cisco switches.
PTP over DLR topology and use cases
Describes common topologies and use cases for implementing PTP over DLR in network environments.
Restrictions for multiple VLAN support and PTP over DLR
Consider the limitations and restrictions when using multiple VLAN support and PTP over DLR.
Configuring PTP over DLR
Describes the process of configuring Precision Time Protocol (PTP) over Device Level Ring (DLR) networks to achieve time synchronization across industrial Ethernet devices in ring topology configurations.
Show CLI commands
Lists the show commands that you can use for PTP and provides examples of their output.
Feature history for changing VLANs with PTP transparent clock
Provides release and related information for features explained in this chapter.
