Configuring Class-of-Service Match Conditions

To configure CoS match conditions, include the from statement at the [edit services cos rule rule-name term term-name] hierarchy level:



[edit services cos rule rule-name term term-name]

from {

applications [ application-names ];

application-sets [ set-names ];

destination-address address;

source-address address;
}

You can use either the source address or the destination address as a match condition, in the same way that you would configure a firewall filter; for more information, see the JUNOS Policy Framework Configuration Guide.

If you omit the from term, the router accepts all traffic and the default protocol handlers take effect:

User Datagram Protocol (UDP), Transmission Control Protocol (TCP), and Internet Control Message Protocol (ICMP) create a bidirectional flow with a predicted reverse flow.
IP creates a unidirectional flow.

You can also include application protocol definitions that you have configured at the [edit applications] hierarchy level; for more information, see the JUNOS Services Interfaces Configuration Guide.

To apply one or more specific application protocol definitions, include the applications statement at the [edit services cos rule rule-name term term-name from] hierarchy level.

To apply one or more sets of application protocol definitions you have defined, include the application-sets statement at the [edit services cos rule rule-name term term-name from] hierarchy level.

Note: If you include a statement that specifies application protocols, the router derives port and protocol information from the corresponding configuration at the [edit applications] hierarchy level; you cannot specify these properties as match conditions.
