The following table shows the instance-specific configuration options for the Freerun sync module. These must be in a section labeled with the instance name.

Table 1. Instance-specific Configuration Options for the Freerun Sync Module
Option Parameters Description
interface <interface-name> Specifies the name of the interface hosting the local reference clock.
priority <number>

Relative priority of sync module instance. 1 Smaller values have higher priority.

The default is 128.

  1. If the priority is specified in a generic section, outside of a specific (named) sync instance, the priority will apply to all sync modules of the same type. For example:
    sync_module freerun namedfreerun1 namedfreerun2
    
    [freerun] 
    // this applies to all freerun type sync module instances
    priority 128
    
    [namedfreerun1]
    // this applies only to this instance - and takes priority over any generic value
    priority 127
    
    [namedfreerun2]
    // this applies only to this instance - and takes priority over any generic value
    priority 126
