In the Advanced Path Settings, the system provides the following built-in groups of parameters for you to customize the values of QoS parameters for the source device before calculating a path, including QoS, Protocol, URL, and Application.

If you want to customize the parameter fields displayed in the GUI, do the following:

1. In the Domain Management page, navigate to Operations > Domain Settings > Path Parameters Settings. By default, the system defines four groups of parameters in JSON as follows:

[
    {"name":"group1", "type":"group", "label":"QoS", "value":"", "enable":true},
    {"name":"CoS", "type":"int", "label":"CoS Value", "value":"", "enable":true},
    {"name":"DSCP","type":"string", "label":"DSCP Value", "value":"", "enable":true},
    {"name":"Precedence", "type":"int", "label":"Precedence Value", "value":"", "enable":true},
    {"name":"QoS-Group", "type":"int", "label":"QoS-Group Value", "value":"", "enable":true},

    {"name":"group2", "type":"group", "label":"Protocol", "value":"", "enable":true},
    {"name":"Protocol", "type":"string", "label":"Protocol Value", "value":"", "desc":"Identify the protocol is IPinIP or IP", "enable":true},

    {"name":"group3", "type":"group", "label":"URL", "value":"", "enable":true},
    {"name":"URL", "type":"string", "label":"URL Value", "value":"", "desc":"Identify the url", "enable":true},

    {"name":"group4", "type":"group", "label":"Application", "value":"", "enable":true},
    {"name":"Application", "type":"string", "label":"Application Value", "value":"", "desc":"Identify the application", "enable":true}
]
