Description

On the MX Series, configure the G.8275.1 or the enhanced G.8275.1 PTP profile for applications that require accurate phase and time synchronization. This profile supports the architecture defined in ITU-T G.8275 to enable the distribution of phase and time with full timing support and is based on the second version of PTP defined in IEEE 1588.

On QFX Series switches that support the enterprise-profile feature, you can configure the enterprise profile, which supports IEEE 1588 PTPv2 transport over multicast IPv4. If you do not specify a profile, the IEEE 1588 default profile is enabled by default.

On QFX Series switches that support the G.8275.2 enhanced profile feature, you can configure the G.8275.2 enhanced profile, which supports telecom applications that require accurate phase and time synchronization for phase alignment and time of day synchronization over a wide area network. This profile supports PTP over IPv4 unicast, ordinary and boundary clocks, and unicast negotiation.

On QFX Series switches that support the media profile, you can configure the SMPTE, AES67, and the AES67+SMPTE profiles to support video applications for capture (for example, cameras), video edit, and playback to be used in professional broadcast environments. The standard allows multiple video sources to stay in synchronization across various equipment by providing time and frequency synchronization to all devices. This profile supports PTP over IPv4 multicast and ordinary and boundary clocks.

ACX 710 devices support G.8275.2 profile with node type T-BC-P (BC).

ACX5448, ACX5448-D, and ACX5448-M devices support ACX G.8275.2 enhanced profile. You can configure the G.8275.2 enhanced profile, which supports telecom applications that require accurate phase and time synchronization for phase alignment and time of day synchronization over a wide area network. This profile supports PTP over IPv4 and IPV6 unicast traffic.

ACX710, ACX2100, and ACX2200 devices support G.8275.1 telecome profile. This profile supports the architecture defined in ITU-T G.8275 to enable the distribution of phase and time with full timing support. This profile requires all devices in the network to operate in combined or hybrid modes, which means that PTP and Synchronous Ethernet are enabled on all devices.

Options

aes67

Enable the AES67 PTP profile.

aes67-smpte

Enable the AES67+SMPTE PTP profile.

enterprise-profile

Enable the enterprise profile. The enterprise profile supports IEEE 1588 PTPv2 transport over multicast IPv4. When the enterprise profile is enabled, no other profiles can be enabled. Also, unicast negotiation is disabled when you enable the enterprise profile.

g.8275.1

Enable the G.8275.1 PTP profile.

g.8275.1.enh

Enable the enhanced G.8275.1 PTP profile. This profile supports PTP over IPv4.

g.8275.2

Enable the G.8275.2 PTP profile.

g.8275.2.enh

Enable the enhanced G.8275.2 PTP profile.

smpte

Enable the SMPTE PTP profile.
