CoS revert and direction awareness on services interfaces

More Information:

CoS revert and direction awareness on services interfaces

You can configure a services interface CoS rule to store the DSCP and forwarding class of a packet that is received in the match direction of the rule and then apply that DSCP and forwarding class to packets that are received in the reverse direction of the same session. You can also configure a services interface CoS rule to create a CoS session if a packet is first received in the wrong match direction, resulting in the CoS rule values being applied as soon as a packet in the correct match direction is received. To apply the stored DSCP and forwarding class to packets in the reverse direction, include the revert statement at the [edit services cos rule rule-name term term-name then] hierarchy level. If you use the revert statement, you cannot use the reflexive or reverse statements. To create the CoS session if a packet is first received in the wrong match direction, include the match-rules-on-reverse-flow statement at the [edit services service-set service-set-name cos options] hierarchy level.
