ptp-clock transparent

Enables transparent clock (TC) mode for precision time protocol (PTP).
Syntax
ptp-clock transparent pkt-type ethernet option e2e step-type onestep
no ptp-clock transparent pkt-type ethernet option e2e step-type onestep
Command Default

The PTP-TC configuration is disabled by default on all interfaces.

Modes

Global configuration mode

Interface configuration mode

Usage Guidelines

The ICX7850-32Q, ICX7150-24(Non PoE) and ICX7150-12P devices support PTP packet prioritization and end to end transparent clock mode.

FastIron 08.0.95 supports the end-to-end PTP-TC mode of operation for standalone and stacking topologies.

The PTP-TC can be enabled globally. All the ports are configured for timestamping after the transparent clock is configured globally.

Enable each port individually if you want to enable or disable timestamping on an individual port or range of ports.

Examples

The following example enables the PTP transparent clock mode globally.

device# configure terminal
device(config)# ptp-clock transparent pkt-type ethernet option e2e step-type onestep
PTP Feature Enabled

The following example enables the PTP transparent clock mode on individual ports.

device# configure terminal
device(config)# interface ethernet 1/1/5
device(config-if-e25000-1/1/5)# ptp-clock transparent pkt-type ethernet option e2e step-type onestep
PTP Feature Enabled on port 1/1/5

The following example enables the PTP transparent clock on a range of ports.

device(config-if-e25000-1/1/5)# interface ethernet 1/1/10 to 1/1/15
device(config-mif-1/1/10-1/1/15)# ptp-clock transparent pkt-type ethernet option e2e step-type onestep
PTP Feature Enabled on port 1/1/10
PTP Feature Enabled on port 1/1/11
PTP Feature Enabled on port 1/1/12
PTP Feature Enabled on port 1/1/13
PTP Feature Enabled on port 1/1/14
PTP Feature Enabled on port 1/1/15
