inet-precedence (rewrite-name | default) protocol (inet-both | inet-outer | mpls);

[edit class-of-service interfaces interface-name unit logical-unit-number rewrite-rules]

Apply an IPv4 precedence rewrite rule.

`rewrite-name`	Name of a `rewrite-rules` mapping configured at the `[edit class-of-service rewrite-rules inet-precedence]` hierarchy level.
`default`	The default mapping. By default, IP precedence rewrite rules alter the first three bits on the type of service (ToS) byte while leaving the last three bits unchanged.
`protocol inet-both`	Rewrite the inet-precedence CoS value to both the inner and outer header for Unicast/Multicast IPv4 traffic. The first three bits of the CoS value are rewritten and the final six bits are taken from the incoming CoS value.
`protocol inet-outer`	Rewrite the inet-precedence CoS value to the outer header for Unicast/Multicast IPv4 traffic. The first three bits of the CoS value are rewritten and the final six bits are taken from the incoming CoS value.
`protocol mpls`	(Optional for ingress MPLS tunnel nodes) Rewrite the MPLS EXP bits in the MPLS header independently of the IPv4 DSCP value for IPv4 packets entering an MPLS tunnel.
