7210 SAS-MXP, R6, R12, S, SX, T BASIC SYSTEM

CONFIGURATION GUIDE RELEASE 22.9.R1

System management

Description

This command configures a stable frequency reference obtained through one of the line references (SyncE

or bits) for the PTP clock. This is achieved by specifying ssu to be the frequency source for PTP. This

mode of operation where PTP is used only for time recovery, and SyncE or BITS is used for frequency

recovery, is known as PTP hybrid mode.

If the frequency reference is set to ssu, PTP is running in hybrid mode (if PTP is also in a no shutdown

state) using the recovered frequency provided by the central clock through either of the configured

references (SyncE or BITS, whichever is configured as a reference for the central clock). In this setting,

PTP cannot be configured as a reference in the ref-order. The CLI blocks this configuration. The reverse is

also true; that is, if PTP is configured under ref-order, this parameter cannot be set to ssu.

If the frequency reference is set to ptp, PTP runs in pure mode, potentially being configured as a frequency

reference in ref-order.

Note:

See Configuration guidelines and restrictions for PTP for more information about command

usage.

The no form of this command reverts to the default value.

Default

freq-source ptp

Parameters

freq-source

Specifies whether PTP is used for frequency and time recovery, or only for time recovery. If

ptp is specified, PTP is used for both frequency and time recovery. If ssu is specified, PTP

is used only for time recovery.

Values ptp, ssu

clock-type

Syntax
