CoS rewrite rules

Rewrite rules allow you to alter Class-of-Service (CoS) bit values in outgoing packet headers to match the policies of a targeted peer network. You benefit from this feature by ensuring that downstream devices correctly classify each packet into the appropriate service group, maintaining consistent CoS treatment across network boundaries. Each rewrite rule reads the current forwarding class and loss priority associated with a packet, locates the corresponding CoS value from a table, and writes that value into the packet header. You must explicitly assign a rewrite rule to an outbound interface for rewrites to take effect. The goal is to enable seamless CoS policy alignment between your network and neighboring networks.
